First use downloads the OCR engine and language packs (the Chinese packs are large — tens of MB). They are cached by your browser for future visits.
📄 Click to choose PDF files — or drop them anywhere on this page.
Multiple files supported. Everything is processed locally in your browser.

OCR on: every exported page is re-rendered at 200 DPI and paired with an invisible, selectable text layer — the result is searchable and copy-able, ideal for scans and photographed documents. OCR off: pages are copied losslessly from the original file, which is instant and preserves vector quality. Tip: PDFs that already contain digital text (e.g. exported from Word) are best exported with OCR off. The first OCR run downloads the engine and language data; afterwards it is cached and starts immediately. All processing happens on your device — nothing is ever uploaded.
