How it works (3 steps)

Upload a scanned PDF

Clear, upright scans work best. The language model downloads on first use (one-time).

Local OCR

Each page is rendered and recognized in your browser with visible per-page progress.

Download text or searchable PDF

Export plain .txt, or a searchable PDF with an invisible text layer over the original scan.

FAQ

Is my document uploaded for OCR?

No. Recognition runs in your browser via WebAssembly (tesseract.js). The language model is fetched from a CDN once; your file never leaves your device.

How accurate is it?

Good scans of printed Simplified/Traditional Chinese typically recognize well; handwriting and low-quality scans are hit-or-miss. Always proofread. Failed runs refund your quota automatically.

What is a searchable PDF?

Your original scan with an invisible text layer on top — it looks identical but you can select, copy and search the text.
