Highlight parts of an image

Draw translucent highlights over the important parts of an image, then export as PNG or JPG. Everything runs in your browser and stays private.

Privacy-first: every image is processed locally in your browser. Nothing is uploaded, stored or transmitted to any server.

A marker pen for images

The highlight tool draws translucent color over the image — the digital equivalent of running a marker across a printout. The underlying text or detail stays fully readable, which is the crucial difference from boxes and arrows: highlighting says “read exactly this part” without hiding anything.

Documents, receipts, terms and screenshots

Highlight the clause in the contract screenshot, the line item on the receipt, the error in the log. Multiple highlights in different colors distinguish topics; each stays movable and resizable until export. Combine with arrows or blur from the same toolkit, then download as PNG or JPG — all locally.

Frequently asked questions

Is my image uploaded?
No. Every edit is applied on a canvas in your browser; your image is never sent anywhere.
What editing can I do?
Crop, rotate 90° left/right, flip horizontally or vertically, and add text (with font, color and size), arrows, boxes, ellipses and highlights. You can also blur or pixelate regions.
Can I hide sensitive information?
Yes. Use the Blur or Pixelate tools to permanently obscure faces, personal details or private data before sharing.
Can I move and edit things after adding them?
Yes. Switch to Select to move, resize or recolor any annotation; double-click text to edit it. Ctrl+Z / Ctrl+Shift+Z undo and redo, including crops and rotations.
Which formats can I export?
PNG (lossless, keeps transparency) or JPG.
