TL;DR
This guide compares the eight best annotation tools for creative and marketing teams across four asset types: documents and PDFs, designs, video and audio, and live websites. Every tool was assessed for file-type coverage, annotation depth, collaboration and external reviewer access, and pricing relative to value.
Why annotation matters for creative and marketing teams
Feedback is where good creative work either gets sharper or falls apart. When comments live in email threads, Slack messages, and screenshots, the version everyone is working from stops being clear, and small misunderstandings turn into extra review rounds.
Microsoft reports that employees in the highest “ping” volume group are interrupted every two minutes during core work hours by meetings, emails, or chats. For a marketing team juggling campaign assets, that constant context switching is exactly what pulls feedback away from the file it belongs to.
Annotation tools fix that by keeping comments attached to the asset, so you collect feedback right where the work lives. Reviewers can highlight a line, draw on a design, or mark an exact frame in a video, so the person making changes knows precisely what needs to happen and where.
This guide covers the eight best annotation tools for creative and marketing work in 2026, spanning documents and PDFs, designs, video and audio, and live websites. For each one, you’ll get an honest read on what it does well and where it falls short, plus current pricing.
How we evaluated these tools
We compared each tool on four things that matter for creative and marketing review: how many file types it covers, how deep its annotation and markup features go, how easily clients and external stakeholders can join without friction, and how the price stacks up against what you actually get.
Note: Filestage is our own product. We’ve applied the same evaluation criteria here as to every other tool on this list. We didn’t test each platform hands-on, so we cross-referenced live feature pages and current vendor pricing to build this comparison. All pricing was checked in July 2026 and may change, so confirm on each vendor’s own page before you buy.

The eight best online annotation tools for images, videos, PDFs 2026
Here’s the closer look, starting with the platform built to pull all your feedback into one approval process.
1. Filestage – best for review and approval across every file type
Filestage is a review and approval platform that lets your team and clients annotate documents, designs, videos, and other marketing assets in one place. Reviewers can draw on a file, highlight text, or leave in-context comments, and every piece of feedback stays tied to the exact version it belongs to.
Why we chose it
Most tools on this list handle one type of annotation well. Filestage is here because it treats annotation as one step inside a structured review process, with reviewer groups, due dates, version control, and clear approval statuses across every file type. If your bottleneck is chasing sign-off rather than marking up a single PDF, that workflow layer is where it pays off. For a quick one-off markup, a lighter tool will get you there faster.
Key features
- In-context annotation on documents, images, videos, audio, and live websites, all in the same platform
- Side-by-side version comparison so reviewers can compare a new version against the last and see what changed
- Automated review stages with due dates and reminders, so approvals move without manual chasing
- Reviewer groups that route each file to the right people at the right stage
- Unlimited reviewers who can comment without creating an account
Pros
- Covers every common creative file type, so you’re not switching tools between a PDF and a video
- No login needed for external reviewers, which removes friction for clients
- AES 256-bit encryption and a clear audit trail of who said what
- Free plan available for freelancers and smaller teams
Cons
- More than you need for a quick, one-off markup where a lightweight tool would do
- Browser-based, so there’s no offline desktop app for marking up files without a connection
Pricing
Free plan available (one active project, two reviewer groups, unlimited reviewers). Paid plans start at $199/month for the Starter plan, $329/month for the Business plan. 14-day free trial.
“Our content approvals are now much more precise as you can be more specific about the content’s details and make your comment on-the-spot.”

2. Adobe Acrobat – best for document and PDF annotation
Adobe Acrobat is the long-standing benchmark for PDF annotation. It gives you a deep markup toolkit, from highlights and stamps to redaction and OCR, plus the ability to edit and convert PDF files at a level most other tools can’t match.
Why we chose it
When your work lives in PDFs and you need real editing power alongside your markup, Acrobat is hard to beat. What sets it apart is the sheer depth of its document tools, not its collaboration, which is where a review platform pulls ahead. If your team’s real need is gathering feedback from clients across many file types, you’ll find Acrobat’s review workflow more fiddly than a purpose-built approval tool.
Key features
- Extensive markup tools, including highlight, strikethrough, custom stamps, and freehand drawing
- Redaction and OCR to convert scanned documents into searchable, editable text
- Real-time commenting through Adobe Document Cloud
- Deep integration with the rest of Adobe Creative Cloud
Pros
- The most comprehensive PDF editing and markup set available
- Excellent OCR for turning scanned files into workable documents
- Trusted, industry-standard format support that clients rarely question
- Available on both desktop and mobile, so you can mark up on any device
Cons
- Collaboration is clunkier than a dedicated review platform, especially with external clients
Pricing
No free plan, but there’s a 7-day free trial. Acrobat Standard for individuals starts at $14.99/month, Acrobat Pro at $19.99/month, on an annual plan.
3. Frame.io – best for audio and video annotation
Frame.io, part of Adobe, is built for video teams that need precise, frame-accurate feedback. Reviewers can drop a comment on an exact frame, sketch on the video, and see notes sync straight into their editing software.
Why we chose it
For video annotation, the difference between “somewhere near the end” and a comment pinned to frame 1,204 is the difference between one revision and three. Frame.io stands out here because its comments are frame-accurate and flow directly into Premiere Pro and Final Cut Pro, which keeps editors in their workflow. If you’re mostly reviewing documents and designs rather than footage, its video-first focus will feel narrow.
Key features
- Frame-accurate and range-based comments pinned to exact moments
- Annotations you can draw directly on a frame
- Camera to Cloud, so footage uploads the moment a shoot wraps
- Integrations with Premiere Pro, Final Cut Pro, and other editing tools
Pros
- Best-in-class precision for video feedback
- Comments sync into the editor, so notes don’t get lost in translation
- Handles large video files smoothly, where general-purpose tools tend to choke
- Free plan for individuals and small teams
Cons
- Focused on video and audio, so it’s a poor fit as your only tool if you review a lot of documents and designs
Pricing
Free plan available, with two members and 2 GB storage. The Pro plan starts at $15/member per month on an annual plan.

4. Markup.io – best for annotating any file type at a flat team rate
Markup.io is a visual feedback tool that lets you comment on websites, images, PDFs, and videos, with support for more than 30 file types. Its pitch is simple: one flat monthly price, no matter how many people you add.
Why we chose it
For teams that hate per-seat math, Markup.io’s flat rate is the draw. You pay one price and add as many users, clients, and stakeholders as you like, which makes it easy to scale reviews without watching the bill climb. That pricing model, paired with broad file-type support, is the real reason to pick it over a similar tool. The catch is that the entry price is high for a small studio, since a two-person team pays the same as a twelve-person one.
Key features
- Support for 30+ file types, including websites, images, PDFs, and video
- Unlimited users on every plan
- Contextual commenting with threaded replies
- Integrations with project management and design tools
Pros
- Flat pricing that doesn’t punish you for adding reviewers
- Broad file-type coverage in a single tool, simple enough for non-technical clients
Cons
- No ongoing free plan since 2025, only a 14-day trial
- The flat $79/month is steep for solo freelancers or very small teams
Pricing
No free plan. The Pro plan is $79/month with unlimited users, and there’s a 14-day free trial. Enterprise pricing is quote-based.
5. Pastel – best for website and marketing asset feedback
Pastel lets you drop comments straight onto a live website by pasting in a URL, with no code to install. It also handles PDFs, images, and other marketing assets, which makes it a handy pick for smaller teams reviewing client work.
Why we chose it
Pastel makes website feedback almost frictionless: share a link, and clients can annotate the live site without an account or a plugin. Compared to a heavier review platform, its draw is that simplicity plus a low entry price for small teams. If you need to route feedback into a developer’s workflow with technical detail attached, a bug-focused tool will serve you better, which is exactly where the next pick comes in.
Key features
- Comment directly on live websites using Pastel’s proxy, with no code required
- Support for PDFs, images, and other digital assets
- Unlimited guest reviewers on every plan
- Export comments to CSV, and to tools like Trello, Asana, Jira, and Zapier on higher tiers
Pros
- No-code setup for website feedback, which non-technical clients love
- Free Forever plan for solo users
- Affordable entry point for small teams
- Handles live sites and static assets in one place, not just web pages
Cons
- Per-user pricing on paid plans adds up as your team grows
- Lighter on technical detail than a dedicated bug-reporting tool
Pricing
Free Forever plan available for one user with one active canvas. The Pro plan starts at $29/month for two users, billed annually. There’s a 14-day trial on paid plans.

6. Marker.io – best for website feedback that hands off to developers
Marker.io is a website feedback and bug-reporting tool that captures visual annotations along with the technical metadata developers need to reproduce an issue. It turns a marked-up screenshot into a ready-to-action task in Jira, GitHub, or your issue tracker of choice.
Why we chose it
Where Pastel keeps things simple for clients, Marker.io is built for the handoff to a dev team. Each report bundles the annotation with browser, OS, and console details, so a developer can reproduce the issue without a follow-up email. That developer-focused workflow is what separates it from the other website tools here. It does lean more toward product and QA teams than pure creative review, so weigh that against how your team is structured.
Key features
- Visual annotation on any webpage via a widget or browser extension
- Automatic capture of technical metadata with every report
- Two-way integrations with Jira, GitHub, Trello, Asana, and ClickUp
- Free, unlimited reporters who can submit feedback without an account
Pros
- Bridges the gap between marketing feedback and developer action
- Rich technical context speeds up bug fixes
- Unlimited reporters keep client and stakeholder input free
- Deep two-way sync with issue trackers, so nothing is retyped by hand
Cons
- Aimed more at dev and QA workflows than creative review
- No ongoing free plan, only a 15-day trial
Pricing
No free plan. The Starter plan is $39/month billed annually for three users, with a 15-day free trial. Business pricing is quote-based.
7. GoVisually – best for design proofing for creative agencies
GoVisually is a proofing and approval tool aimed at creative agencies and marketing teams. It lets you mark up designs, PDFs, and videos, then collect feedback from clients and stakeholders as files move through review.
Why we chose it
GoVisually keeps design proofing simple, which is its strength for agencies that want feedback and sign-off without a learning curve. What it offers over a broader tool is ease of use and an agency-friendly setup with unlimited reviewers. If you need a free tier to try it indefinitely, note that GoVisually only offers a short trial rather than a lasting free plan.
Key features
- Markup tools for designs, PDFs, images, and video
- Unlimited external reviewers on every plan
- Straightforward approval routing that keeps client sign-off moving
- Adobe, Slack, and Zapier integrations on higher tiers
Pros
- Clean, simple interface that clients pick up quickly
- Unlimited reviewers keep external feedback free
- Built specifically around agency proofing workflows
- Version comparison makes it easy to see what changed between proofs
Cons
- No free plan, only a 7-day trial before you commit
Pricing
No free plan. The Lite plan starts at $16/user per month on an annual plan, and the Pro plan is $33/user per month. There’s a 7-day free trial.
8. PDF Annotator – best for solo PDF markup on Windows desktop
PDF Annotator is a Windows desktop application for marking up PDFs by hand. It’s built for individuals who want to highlight and stamp on documents with a stylus or mouse, then save everything back into the original PDF.
Why we chose it
Not every job needs a cloud platform. PDF Annotator is here for the person who wants fast, offline PDF markup on a Windows machine and would rather pay once than subscribe. Nothing else on this list is a desktop app with a one-time license, which is the whole reason it makes the cut. Just be clear on what it isn’t: there’s no collaboration or cloud sync, and no version tracking, so it’s a solo tool rather than a team one.
Key features
- Full handwritten markup with pen, highlighter, and stamps
- Works entirely offline as a desktop application
- Saves annotations straight back into the source PDF
- One-time perpetual license rather than a subscription
Pros
- Pay once and own it, with no recurring fee
- Fast, offline markup that doesn’t need an account
Cons
- Windows only, with no Mac or web version
- No collaboration or cloud sync, so it can’t support team review
Pricing
No free plan, but there’s a 30-day free trial. A single perpetual license is $79.95 as a one-time purchase.
How to choose the best annotation tool for your needs
Start with the file types you review most. If your work is mostly documents and PDFs, Adobe Acrobat or PDF Annotator give you the deepest markup, while Frame.io is the clear pick if video is your main asset. If you review a bit of everything, from campaign briefs to social videos, a platform that covers all file types in one place will save you from switching tools mid-project.
Then factor in team size and how much of your feedback comes from outside. Tools like Pastel, Filestage, and GoVisually keep external reviewers free, which matters when clients and stakeholders make up most of your reviewers. If you’d rather not count seats at all, Markup.io’s flat rate scales cleanly as you add people. For teams that need feedback to turn into developer tasks, Marker.io is built for that handoff.
Finally, weigh how structured your process needs to be. A lightweight commenting tool is fine for the occasional markup. But if your real challenge is moving work from draft to approved without losing track of who signed off, Filestage connects annotation to a full review and approval workflow across every file type, which is where most creative and marketing teams get their time back.o allows project managers to have all feedback comments in one place, making execution easier.
Final thoughts
The right annotation tool depends less on which has the longest feature list and more on how your team actually works. Match the tool to your file types and the way your team actually reviews work, and you’ll cut revision rounds and get clean sign-off faster.

FAQ
What is an annotation tool?
An annotation tool is software that lets you add comments, highlights, drawings, and notes directly onto content like documents, images, videos, or live websites. Instead of describing a change in a separate email or message, you mark it on the file itself, so whoever picks up the work knows exactly what to do and where. Creative and marketing teams rely on them for design review, video feedback, website proofing, and document sign-off.
How do I annotate a PDF?
Upload your PDF to an annotation tool, then use the markup tools to highlight text, draw on the page, or leave a comment tied to a specific spot. Tools like Adobe Acrobat and Filestage let you add notes in context, so whoever makes the edits knows exactly what to change. For a full walkthrough, see our guide to PDF annotation software.
Which annotation tool is best for video feedback?
For frame-accurate video feedback, Frame.io is the strongest pick because comments pin to an exact frame and sync into editing software like Premiere Pro. Filestage is a good alternative if you review video alongside other file types and want it all in one review workflow.
Can I annotate a website with these tools?
Yes. Pastel lets you comment directly on a live website by pasting in a URL, with no code to install, which makes it easy for clients to join. Marker.io does the same but adds technical metadata for developers, and Filestage also supports live website review inside its approval process.
Are there free annotation tools for marketing teams?
Several tools offer a genuine free plan rather than just a trial. Filestage, Frame.io, and Pastel all have free tiers suited to freelancers and smaller teams. Check the limits on files, storage, and reviewers before you rely on one, since free plans are capped.
What’s the difference between an annotation tool and a review and approval platform?
A basic annotation tool lets you mark up a file and leave comments. A review and approval platform like Filestage adds the workflow around it: reviewer groups, due dates, version control, and clear approval statuses, so feedback turns into a signed-off decision. If your team runs regular review cycles across many file types, that structure is what saves time.
