Remove Highlight from Image Seamlessly with AI-Powered Technology in seconds

Remove Highlight from Image is a free online AI tool that removes highlighter colour from scans and photos of printed pages, for students and researchers who want clean copies. Use it when old highlighting makes a page hard to read or share. It is not reliable when highlighter has bled through the text itself; very dark marks may leave traces.

Highlighting is a universal study and review tool. Students annotate textbooks with yellow and pink highlighter. Professionals mark up printed contracts and reports. Researchers circle and highlight key passages in academic papers. But when these highlighted documents need to be scanned and distributed digitally — or when the highlighted copy needs to be cleaned for reprinting — the colored marks create a problem.

Highlighter marks are semi-transparent: the yellow or pink or green tint sits over the text, tinting the underlying content without fully obscuring it. This semi-transparent nature makes highlighter marks particularly tricky to remove with traditional tools. They're not fully opaque (so simple masking doesn't work), but they're not invisible either (the color distortion is obvious in scans). Photoshop's healing brush and clone stamp struggle with the semi-transparent color overlay, often leaving a visible color cast even after editing.

Our AI diffusion model handles the semi-transparent nature of highlighter marks specifically. The model identifies the color overlay of the highlight — yellow, pink, green, orange, and other common highlighter colors — and removes the color tint while reconstructing the underlying text and paper background to their original un-highlighted state. The text that was highlighted becomes fully readable and the paper background returns to clean white or cream.

This is particularly valuable for document professionals: legal teams that receive highlighted contracts need clean versions, archivists digitizing annotated historical documents want highlight-free scans, teachers who receive highlighted worksheets need clean copies for redistribution, and businesses that circulate printed documents for review need the ability to clean annotation marks before final distribution.

Highlighter removal from standard document scans produces consistently clean results. The tool handles most common highlighter colors and works well for documents with standard white or cream paper backgrounds. Processing takes about 10 seconds. No Photoshop, no design skills, no signup required.
