Turn Scanned PDFs Into Searchable, Editable Text

Have a scanned PDF that you can't copy text from? PDFino uses Tesseract.js — a powerful open-source OCR engine — to recognize and extract text from scanned documents directly in your browser. No cloud processing, no API calls to external services. Your scanned documents stay completely private on your device while the OCR engine identifies and extracts every word.
