PDF OCR

PDF OCR

Turn scanned PDFs into searchable, selectable text.

Run optical character recognition on scans, faxes and image-only PDFs. The output is a normal PDF that looks identical to the original, but with an invisible text layer you can search, copy and index.

Files auto-deleted within 1 hour · no signup for basic use

How it works

Four calm steps.

  1. 01

    Drop your file

    Drag the scanned PDF 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 the language

    Choose one or several languages so recognition matches the alphabet and diacritics. 30+ languages supported.

  3. 03

    Let us do the work

    Our engine recognises text and injects an invisible layer behind the page images in a few seconds. Nothing leaves the encrypted pipeline while it runs.

  4. 04

    Download the result

    Save the searchable 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 PDF OCR

Built to be the last pdf ocr tool you try.

Quality that holds up

Character accuracy on clean scans reaches 99 %+, even on tightly-set documents.

Multi-language

Latin, Cyrillic, Greek, Arabic, Hebrew and CJK scripts recognised, mixable on the same page.

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.

What is a searchable PDF?

A PDF where you can Ctrl+F to find text, even though the visible layer is an image scan.

Can I extract the recognised text?

Yes – use the Extract Text tool afterwards, or open the OCR'd PDF in any reader and copy-paste.

Is PDF Books Lib really free?

Yes. The free tier covers everyday use – you can OCR 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 Multi-language free to use?

Yes. Multi-language 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 Multi-language?

No. Multi-language 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 Multi-language?

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 Multi-language can handle?

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

Does Multi-language work on mobile and every browser?

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

How accurate is Multi-language?

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