OCR PDF — Scanned PDF to Text
OCR PDF extracts the text from scanned documents — PDFs that are really just photographs of pages, where normal text extraction returns nothing. Each page is rendered to an image and recognized by the Tesseract OCR engine running locally via WebAssembly, with progress shown per page. Copy the result or download it as a text file. Sensitive scans never leave your device.

To OCR a scanned PDF, open it here — each page is rendered and run through the Tesseract OCR engine compiled to WebAssembly, entirely in your browser. You get the recognized text per page, ready to copy or download as a .txt file. Because nothing is uploaded, it's safe for contracts, statements and IDs.

- Choose a scanned PDF (a few pages works best — OCR is compute-heavy).
- Pick the document's language and start recognition; progress is shown per page.

Perguntas frequentes
How do I extract text from a scanned PDF for free?
Open the PDF on this page and run OCR — the recognition happens in your browser at no cost, with no page limits or sign-up. If your PDF already has selectable text, the faster PDF to Text tool reads it directly.
Why is it slow on long documents?
OCR is genuinely compute-intensive, and here it runs on your device rather than a server farm — that's the privacy trade-off. Expect a few seconds per page; very long scans are better processed in chunks (split the PDF first).
Which languages are supported?
English, Spanish, French, German, Portuguese, Italian and Hindi are offered in the picker; the underlying engine downloads the language model on first use.
How accurate is it?
On clean 300-DPI scans of printed text, accuracy is high. Skewed, low-resolution or handwritten pages recognize poorly — no OCR engine handles handwriting reliably.
Is my PDF uploaded?
No — rendering and recognition run entirely in your browser. The engine and language data download once; your document never leaves your device.
