Mark up and redact a screenshot
Annotations turn a screenshot into a clear explanation. An arrow points to the button you mean, a box highlights the area that matters, a text label names a feature, and a blur hides an email or a card number before you share. It's everything you need for bug reports, tutorials, feedback, and support replies.
This tool gives you all four directly on the preview. Pick a tool and a colour, then drag on the image to draw. You can stack as many annotations as you like, undo the last one, or clear them all — and you can still add a frame and background around the marked-up screenshot before exporting.
How to annotate a screenshot
- Open your screenshot. Drag it in, paste it, or choose a file.
- Pick an annotation tool. Choose arrow, box, blur, or text, then a colour.
- Draw on the preview. Drag to place arrows and boxes, drag over a region to blur it, or click to drop a text label.
- Download. Export the annotated screenshot as PNG, JPG, or WebP.
Blur before you share
Before posting a screenshot publicly, drag the blur tool over anything private — names, email addresses, account numbers, API keys. The blurred region is pixelated in the exported image, so the hidden text can't be read back.

Annotate screenshot tips
- Annotations are stored in screenshot-space coordinates, so they stay locked to the exact pixels they were drawn on even after you add a frame, padding, or a tilt around the image.
- Use the blur tool to redact anything private — names, email addresses, account numbers, API keys — before sharing; it pixelates that region in the exported file, so the hidden text cannot be read back.
- Drag to draw arrows and boxes or to cover a region with blur; click to drop a text label, which gets a dark chip behind it so it stays legible over any background.
- Line thickness, arrowheads, and text size scale with the screenshot width, so markup on a large capture stays proportional rather than turning into hairlines.

Frequently asked questions
What annotations can I add?
Arrows to point things out, rectangles to highlight an area, blur regions to redact sensitive parts, and text labels. Each can be a different colour.
Does the blur actually hide the information?
Yes. The blur pixelates the selected region in the exported image, so the underlying text isn't recoverable from the saved file.
Can I undo an annotation?
Yes. Use 'undo last' to remove the most recent annotation, or Clear to remove them all.
Where is my image processed?
