OCR PDF — Convert Scanned PDF to Searchable Text
Unlock text locked inside scanned PDFs, book scans, photographed documents, and image-only files. Optical Character Recognition (OCR) analyzes each page, recognizes letters and words, and produces a searchable PDF where you can find, highlight, and copy text. The recognition engine runs directly in your browser via Web Workers — your scanned documents are never uploaded anywhere, keeping private scans completely confidential.

Frequently Asked Questions
What does OCR PDF do?
OCR (Optical Character Recognition) detects letters and words in scanned or photographed PDFs and creates a searchable PDF with an invisible text layer. You can then select, copy, and search text that was previously locked inside images.
Are my scanned documents uploaded to any remote server?
No. The OCR engine runs entirely in your browser using Web Workers. Your scans never leave your device, ensuring complete privacy for confidential documents like medical records or legal filings.
Can I copy text from the output PDF?
Yes. The resulting PDF contains a full text layer with selectable, copyable, searchable text that works in Adobe Reader, Chrome, and any standard PDF viewer.
How accurate is the text recognition?
Accuracy is excellent for clean, high-resolution scans with standard fonts. Handwriting, decorative fonts, very low-resolution images, or skewed pages may produce some errors — for best results, use straight, well-lit scans at 300 DPI or higher.
Which languages does OCR support?
The engine supports English and many other Latin-script languages. Recognition quality is best for printed text in common fonts.
