Features

Powerful, layout-aware, privacy-first document translation

Layout fidelity

Dual-engine architecture: direct text-stream editing plus a vision pipeline. Tables, formulas and superscripts survive.

Text inside images

Scans, slides and embedded charts: erase original text and refill in place without breaking the layout.

Searchable output

Image-based pages get an invisible text layer, so translations stay searchable and copyable.

Multilingual

zh · en · ja · ko · fr · de · es · ru, with automatic source detection.

Glossaries

Pin your terminology for consistent long documents; bulk import supported.

Privacy first

Files are used only for this translation, cleaned up on schedule, never used for training.

Which formats are supported?＋

PDF (digital & scanned), DOCX, PPTX, XLSX, TXT and images (JPG/PNG). One entry point; routing is automatic.

Can it translate scans and images?＋

Yes. Pages without a usable text layer go through OCR + in-place refill, with a searchable text layer added.

Do I need an account?＋

No. Guests get a monthly free quota; signing up adds more quota, glossaries and email notifications.

How does the watermark work?＋

Free users get 5 watermark-free files per day; further files carry a light watermark. Paid plans are watermark-free.

How long does it take?＋

Digital PDFs run at seconds per page; scanned pages take a bit longer. Queue position and progress are shown live.

Is my file safe?＋

Encrypted direct upload to private storage with scheduled cleanup; only you can download the results.
