How to OCR a scanned PDF

Upload a scanned PDF and choose the OCR language. SnapKit renders each page at high resolution, runs Tesseract OCR in a Web Worker, and shows editable text beside the original page preview.

All processing runs locally in your browser. Your documents never leave your device.

Why choose SnapKit? Our tools are 100% Private, No Server Upload, Instant Browser-Based, with No File Size Limit.
