OCR a scanned PDF

Turn a scanned PDF into a searchable one: the text is read in your browser and added as an invisible layer, so you can search, select and copy it. Nothing is uploaded.

How it works

OCR a scanned PDF in 3 steps

1

Choose a scanned PDF

Drop a scan or a photo saved as PDF — it opens on your device.

2

Pick the language

English, Spanish, French, German, Portuguese or Italian. The pages are read one by one in your browser.

3

Download

Save the searchable PDF, or open it in the editor to change the text.

How the text is read

Each scanned page is drawn at 300 dpi and read by Tesseract, the open-source OCR engine, running inside your browser tab. Its files are served from this site, so your document is never sent anywhere — not even to a text-recognition service.

The first time you use it, your browser downloads the reader and one language model (about 7 MB); after that it's cached. Pages are read one at a time, a few seconds each on a laptop, slower on phones.

What you get back

The same PDF with the recognized words added as invisible text exactly over the printed ones: search finds them, you can select and copy them, and screen readers can read them. Pages that already had real text are left untouched.

Text is only added where the reader is confident. Lines it can't read reliably — a page scanned upside down or sideways, handwriting, heavy noise — are left out rather than filled with wrong words, and you'll be told when a page had no readable text.

FAQ

Common questions

How accurate is it?

Accuracy depends on the scan. Sharp, straight scans usually come out almost word-for-word; blurry photos, handwriting, tiny print or pages scanned at an angle come out worse. Words the reader isn't sure about are left out rather than guessed.

Which languages can it read?

English, Spanish, French, German, Portuguese and Italian. Pick the document's language before you start.

Will the scan look different?

No. The page image stays exactly as it was. The recognized text is added as an invisible layer on top, the way Adobe's OCR does it.

Are my files uploaded?

No. The conversion runs entirely in your browser using JavaScript — your file never leaves your device, so it's safe even for sensitive documents.

Is it free?

Yes — completely free, no signup, no watermark, and no daily limits.

My scan is sideways or upside down — what now?

Rotate it upright first (for example with your scanner or phone app), then run OCR again. The reader expects text the right way up.

Can I edit the text after OCR?

Yes — choose “Open in editor” when it's done. The recognized lines become editable like any PDF text. Editing is free; downloading an edited document is a one-time $1.97.
