Browser-based screenshot annotation
Annotate screenshots online and make every change obvious
Turn a raw screenshot into a clear instruction without installing another desktop app. Screenshot Annotator gives you one focused browser workspace for pointing to a pixel, explaining the change, hiding sensitive details, and exporting the result.
Why annotate the handoff
- Point to the exact detail — Use arrows, shapes, text, and highlights so the reader knows exactly where to look.
- Protect sensitive context — Blur private information before a screenshot is added to a ticket, document, or support reply.
- Keep annotations editable — Move, resize, restyle, undo, and refine every element before you export the final image.
From screenshot to clear next step
- 1. Upload your screenshot — Choose a PNG, JPEG, or WebP image and open it in the browser editor.
- 2. Add clear annotations — Place arrows, callouts, shapes, highlights, and text around the details that matter.
- 3. Export and share — Download a PNG on the Free plan or use a paid plan for more formats and export controls.
A faster alternative to explaining a screenshot in paragraphs
A screenshot already contains most of the context a teammate needs. Annotation adds the missing instruction: what is wrong, where the change belongs, and what the expected result should be.
That makes an annotated screenshot useful for bug reports, design feedback, customer support, product documentation, and release communication. The same marked-up image can move through the workflow without the meaning being rewritten in every tool.
What you can add to a screenshot
Choose the smallest annotation that communicates the point clearly. A few precise marks are easier to scan than a crowded image.
- Arrows for direction and exact targets
- Text for concise context or expected behaviour
- Rectangles and shapes for grouping an interface area
- Highlights for drawing attention without hiding content
- Blur for redacting names, account details, or private values
