How to OCR a Scanned PDF in Your Browser (Free)
Turn a scanned PDF into selectable text with free browser OCR. Step-by-step using AllToolHub’s OCR PDF tool—no account required.
What OCR does
Optical character recognition (OCR) reads text from images—like a phone scan of a paper form—so you can search, select, and copy words instead of staring at a flat picture of a page.

Privacy
Scans often contain the most sensitive data you handle. Browser-local OCR is a strong default compared with uploading tax packets to unknown servers. Background: privacy-first tools.
FAQ
Does OCR work on every language?
Accuracy depends on language data and image quality. English is the common default; check the tool UI for language options if you need others.
Can OCR fix a blurry photo?
No tool invents missing pixels perfectly. Reshoot or rescan when possible.
