Highlight part of an image online
Highlight text in a screenshot or draw attention to part of a photo, like a marker pen. Drag over the area, pick a colour, and save. It runs entirely in your browser, with nothing uploaded. The highlight blends like a real highlighter, so text underneath stays readable.
How to highlight part of an image
- Paste with Ctrl+V, or drag-and-drop / load your image.
- The highlight tool is ready in soft yellow. Drag a box over the text or area to mark.
- Change the colour from the swatch, or the strength with the Opacity control.
- Copy with Ctrl+C, or save as PNG.
Highlight text in a screenshot
Drag the marker across a line of text to call it out. Because the highlight uses a multiply blend, the words underneath stay crisp and readable instead of being washed out, just like running a highlighter over a printed page.
Highlight an area of a photo
Mark a region of a photo or diagram to draw the eye to it. Pick a bold colour for contrast, or lower the opacity for a subtle tint, and add as many marks as you need.
Highlight vs. boxes and arrows
A translucent highlight emphasises without hiding what is underneath. To point at something instead, add an arrow or a box; to cover a detail for good, use a solid redaction box or a blur.
Private, on-device highlighting
Many online editors upload your image to a server first. This one composites the highlight locally and bakes it into the export, so the image never leaves your device.
FAQ
Will the text under the highlight stay readable?
Yes. The marker uses a multiply blend, so it tints the background while keeping dark text crisp.
Is my image uploaded?
No. Highlighting runs locally in your browser, and the image never leaves your device.
Which formats can I export?
Copy as PNG, or save as PNG, JPEG, or WebP.
