Free image annotation tool: mark up any image, right on the canvas.
Upload a photo, draw over it with the freehand pen, and surround it with captions, comments, and sticky notes. Every markup stays with the image on an infinite canvas, so feedback lives next to the work instead of in a separate email.
Add your image
Drop a JPG, PNG, or WebP onto the canvas and start marking it up in seconds.

How it works
How to annotate an image online.
Three steps from raw image to clear, shareable feedback.
1
Upload your image
Start a free board and add the screenshots or photos under review. JPG, PNG, and WebP all drop straight in, and one board can hold the whole set.
2
Mark it up
Draw over the image with the pen tool, circle what matters, and add captions, comments, and sticky notes around it to explain your thinking.
3
Share for feedback
Send a view-only link so clients and teammates see the annotated board exactly as you left it, or export it as an image or PDF.

Give design feedback people can actually follow.
"Make the logo bigger" means nothing without a picture. Circle the element, draw the change, and pin a note explaining why, so every comment points at the exact pixels it is about.
Direct shoots with marked-up references.
Annotate the references in your photoshoot brief: draw the crop you want, arrow the light source, note what to avoid. The photographer gets direction on the image itself instead of a paragraph describing it.
Sketch camera moves and blocking over frames.
Storyboards come alive when you can draw on them. Arrow a pan across a frame, trace an actor's path, or mark the focal point, and the whole crew reads the shot the same way.
Run visual reviews in one shared place.
Put every asset under review on one board, annotate each one, and let comments collect where the work is. One view-only link replaces the thread of attachments, and nothing gets lost between versions.
Markup, captions, and comments on one canvas.
Storyflow lets you annotate JPG, PNG, and WebP images directly on a visual canvas. Draw over a photo with the freehand pen, add captions under it, pin comments to the discussion, and surround it with sticky notes that carry the context. Use it for design reviews, photo direction, bug reports, storyboard notes, or any moment where words alone will not land.
Annotate and share images online, free.
Marking up images happens entirely in the browser. Drop your images on a board, draw what needs saying, then share a view-only link or export the result as an image or PDF.
Annotations live where the project lives.
Because annotation happens on an infinite canvas, the marked-up image sits next to everything it relates to: briefs, moodboards, tables, and kanban boards. Fix the image itself while you are there with one-click Crop, Remove BG, and Upscale, and the review board becomes the working board.

“Storyflow has sped up my workflow by at least 3x, which means more flow state and more projects I can actually ship. It truly changed the way me and my team create.”

“One prompt gets me a structured board. But the tactics are my favorite. I run my YouTube scripts through them and my intros and retention got better. It's amazing.”

“I used to juggle five apps to plan a project. Now I describe what I am making and get boards, lists, and a schedule. All in one place.”

Frequently asked questions.
Pens, comments, exports, and who can see what.
Upload the image to a board, then draw over it with the freehand pen tool, add captions, and place comments and sticky notes around it. Everything stays anchored to the canvas, so your markup and the image travel together.
Not yet. Storyflow is paid-only during early access, with plans from $7.99 a month billed annually ($9.99 monthly).
