Run OCR on scanned PDFs. Make them text-searchable, or extract plain text. Supports 11 languages.
Recognizes text in scanned/image PDFs. Searchable mode keeps the page image and adds an invisible text layer so you can copy & Ctrl+F search the result. PaddleOCR (PP-OCRv5) is more accurate on Latin / Korean / Cyrillic / Arabic / Devanagari / Tamil / Telugu / Japanese; Tesseract is used for Chinese, Bengali, Urdu, Punjabi, and Gujarati where Paddle's mobile models aren't available.

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.
