How to OCR a scanned PDF — 3 steps
- 1
Add your scanned PDF
Drop the scan into the box above — a photographed contract, an old archive document, a book chapter, a fax.
- 2
Run text recognition
OCR runs in your browser and reads the text on each page image. Clearer scans give better results, but even phone photos usually recognize well.

Turn scans into documents you can actually use
A scanned PDF is just a stack of photographs — you can read it, but you can't search it, copy a paragraph from it, or find it later by its contents. OCR (optical character recognition) reads the pictures and reconstructs the text, turning a static scan into a document that behaves like it was born digital.
That unlocks the everyday tasks scans block: quoting a clause from a photographed contract without retyping it, making years of archived paperwork searchable, extracting tables from printed reports, or making course readings copy-paste-able for notes. Recognition quality depends mostly on the scan — flat, well-lit, 300-DPI-ish pages recognize nearly perfectly; skewed phone photos still do surprisingly well.
OCR is also where privacy matters most, because the documents people OCR are overwhelmingly the sensitive kind: contracts, IDs, medical records, old letters. Most online OCR services process files on their servers. Here, the recognition engine itself is downloaded into your browser and the reading happens on your device — the scan never goes anywhere.
Your files never leave your device
The OCR engine runs inside your browser, so the contents of your scans are read by your own device — and nothing else.
Most online PDF sites upload your document to their servers, process it there, and keep a copy for minutes, hours, or longer. PilotPDF works differently: the page downloads a small processing engine into your browser, and your file is opened and edited in your device's memory using WebAssembly. Nothing is transmitted, so there is nothing for a server to store, leak, or scan. You can even disconnect from the internet after the page loads and the tool keeps working.
