Run OCR on scanned PDFs in your browser via Tesseract.js to make them searchable or extract plain text. 11 languages, hidden text layer keeps the look. Free.
Extract PDF Text only works on digital PDFs that already have a text layer (created from Word, Pages, etc.). OCR PDF works on scanned/image PDFs that are just pixels — it recognizes text from the page images.
No. Tesseract.js runs entirely in your browser. The PDF and the recognized text never leave your device.
Roughly 5-15 seconds per page on a modern laptop. Larger or busier pages take longer. The first page after picking a language is slower because the language pack downloads on first run.
OCR accuracy depends on scan quality, contrast, language, and font. Cleaner scans + the right language pack give the best results. Low-confidence words are filtered out of the searchable layer.
