How it works

Four calm steps.

  1. 01

    Drop your file

    Drag the PDF you want translated onto the upload card, or click to pick it from your device. You can also paste a link to a file hosted online.

  2. 02

    Pick source and target languages

    Auto-detect the source if you are not sure. Fine-tune with a glossary of terms to leave untouched (brand names, code, etc.).

  3. 03

    Let us do the work

    Our engine translates paragraph by paragraph while preserving styling in a few seconds. Nothing leaves the encrypted pipeline while it runs.

  4. 04

    Download the result

    Save the translated PDF to your device, share a temporary link, or send it straight to Google Drive or Dropbox. Files are wiped from our servers within one hour.

Why Translate PDF

Built to be the last translate pdf tool you try.

Quality that holds up

Layout preservation keeps footnotes, tables and captions where they belong – not shoved into a plain text file.

Glossary support

Protect names, product SKUs and code snippets from being translated.

Private by default

Uploads travel over TLS, files are encrypted at rest, and every trace is deleted within 60 minutes. We do not read, index, or train on your documents.

Fast on any device

The heavy lifting happens on our servers, so a Chromebook, an old laptop, or a phone all finish the job in about the same time.

FAQ

Questions people ask.

How many languages?

Over 50, including all EU languages, CJK, Arabic, Hindi and Ukrainian.

Does it work on scanned PDFs?

Yes – OCR runs first, then translation, then re-layout.

Is PDF Books Lib really free?

Yes. The free tier covers everyday use – you can translate several files per hour without an account. Pro unlocks larger uploads and batch jobs.

What happens to my files?

They live in an encrypted staging area for at most one hour, then they are permanently deleted. Nobody on our team can browse them.

Do I need to install anything?

No. Everything runs in your browser against our servers – Windows, macOS, Linux, iOS and Android are all supported.

Is Glossary support free to use?

Yes. Glossary support is free on the no-signup tier with no watermark added to your files. A paid plan only lifts batch and file-size limits for heavy users.

Do I need to install software or create an account for Glossary support?

No. Glossary support runs entirely in your browser - there is nothing to download and no account is required to get started.

Are my files private when I use Glossary support?

Yes. Uploads travel over an encrypted connection, are processed in an isolated pipeline, and are permanently deleted from our servers within 60 minutes. We never read, index or train on your documents.

What is the largest file Glossary support can handle?

On the free tier Glossary support accepts files up to 100 MB. Larger documents are supported on the paid plan, or you can split a big file first.

Does Glossary support work on mobile and every browser?

Yes - Glossary support is fully responsive and works in Chrome, Safari, Edge and Firefox across Windows, macOS, Linux, iOS and Android.

How accurate is Glossary support?

Glossary support uses a modern language model tuned for documents. Results are high quality for most files; always review the output for critical work.
