OCR workflow
When a PDF needs OCR
If Ctrl+F finds nothing, text selection is impossible, or copy-paste returns empty text, the PDF is likely a scan and needs OCR.
OCR workflow
How PDF pages are read
PDF.js renders each page into a temporary canvas in the browser. Tesseract.js reads that image and returns text page by page.

Limits to understand
Very large PDFs can be slow because every page is processed on your own machine. That keeps files private but shifts the work to your browser.

FAQ
FAQ about Unlimited OCR
Can I OCR a multi-page PDF?
Yes. Pages are processed sequentially so progress remains visible and failures can be traced to the exact file.
Does this create a final searchable PDF?
The current browser tool extracts text. Use the searchable PDF page for the output workflow and production limitations.
