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.
