This online screenshot editor is simple yet powerful. Here's how to get started:
Click the upload area to select an image file, or drag and drop an image. Even easier: press Ctrl+V (Mac: Cmd+V) to paste a screenshot directly from your clipboard. Supports JPEG, PNG, WebP, GIF, BMP, and more.
Before drawing, use the color picker, stroke width slider, and font size dropdown in the toolbar. Stroke width ranges from 1-20px, font sizes from 14-48px. Common colors: red for emphasis, yellow for highlights, blue and green for notes.
Click Undo (or press Ctrl+Z) to revert your last annotation. Click Clear to remove all annotations while keeping the original screenshot intact.
Bug Reports & Tech Support: Annotate screenshots with arrows pointing to issues and text describing the problem. Send clear, professional bug reports to your development team or support staff.
Tutorials & Documentation: Create step-by-step guides by highlighting buttons with rectangles, indicating flow with arrows, and adding explanatory text. Export high-quality annotated screenshots for documentation, blog posts, or presentations.
Privacy Protection: Before sharing screenshots, use the Blur tool to obscure phone numbers, ID numbers, bank details, home addresses, and other sensitive personal information. The mosaic effect ensures information cannot be recovered.
Design Reviews & Feedback: Designers and product managers can mark up screenshots with specific feedback — arrows pointing to elements, text describing changes needed. Much more efficient than text-only communication.
No. This tool renders annotations as an overlay on the original image at full resolution. Export as PNG (lossless) or JPEG (adjustable quality).
All browser-supported formats: JPEG, PNG, WebP, GIF, BMP, and more. You can also paste screenshots directly from your clipboard (Ctrl+V).
