Search & Highlight

Find and highlight text in PDF. Right in your browser. 100% free, privacy protected.

Search & Highlight finds every occurrence of a word or phrase across a PDF and highlights them all in one pass. Instead of stepping through matches manually with the reader's find box, you get a document where every mention of a clause, a product name or a defined term is already marked for whoever reads it next. Case sensitivity and whole-word matching keep the results tight, and you can run several terms in different colours. Searching and highlighting both run in your browser.

Frequently Asked Questions

Can I highlight several different terms at once?

Yes, and you can assign a different colour to each, which is how you visually separate categories of term in a long document.

Does it work on scanned PDFs?

Only if the scan has a text layer. Run it through OCR first — that adds searchable text under the image, after which highlighting works normally.

Are the highlights permanent?

They are added as standard PDF highlight annotations, so any reader displays them and they can be removed later by an annotation-aware tool.

Can I match whole words only?

Yes. Whole-word and case-sensitive options are both available, which avoids matching your term inside longer unrelated words.
