AI PDF OCR (Scanned PDF Searchable) is a free, browser-based tool for scanned documents with no text layer. It runs OCR on every page and adds an invisible, precisely-positioned text layer on top of the original page image — so the PDF looks identical, but the text becomes selectable, searchable and copyable.
How to use the AI PDF OCR (Scanned PDF Searchable)
- Upload your scanned PDF.
- Choose the document's language for best OCR accuracy.
- The tool renders each page, runs OCR, and adds an invisible text layer at the correct position.

Frequently asked questions
Will this change how my PDF looks?
No — the original page images are preserved exactly; the OCR text layer is invisible and only affects text selection/search, not appearance.
How accurate is the OCR?
Very good on clear, well-scanned printed text; lower resolution scans, skewed pages, or handwriting will reduce accuracy.
Does this work on already-searchable PDFs?
It will still run and add a text layer, but it's designed for scanned/image-only PDFs that have no existing text.
Is this tool free to use?
Yes, completely free on FreeToolsNets, with no sign-up and no limits.
Is my data sent to a server?
No. Everything runs locally in your browser using JavaScript — nothing you enter is uploaded anywhere.
Does it work on mobile?
Yes, the widget is fully responsive and works on phones, tablets and desktops.
