Reading the text

Every page, no cap

Your processor is doing this, so there is no per-page cost for us to limit. Most free OCR stops at 50 pages because every page costs the site server time.

Languages in this document

Language sizes load with the page. Nothing is downloaded until you start.

What you get

The pictures stay exactly as they are. The text is added underneath them, invisible but selectable, so the page looks identical and can now be searched.

A word the reader is not sure of is left out rather than guessed at, and stays in the picture. A page that is mostly unclear keeps no text at all and is named in the summary. A search that finds the wrong document is worse than one that finds nothing.

Add a file first. These settings are used when you start.

Questions

Is there a page limit?

No. Most free OCR tools stop at 50 pages or 15 MB because every page costs them server time. The reading here happens on your own processor, so a 400-page scan costs us nothing and is not capped. It will take longer, and the progress bar tells you honestly how long.

What if the PDF already has text in it?

The tool checks first and tells you. Running OCR over a PDF that already has a text layer replaces good text with worse text, and every other tool does it silently. If yours is already searchable you will be told, and you can stop.

How accurate is it?

Good on clean printed text, weaker on faint photocopies, unusual fonts and handwriting. Low-confidence regions are kept as the original image rather than replaced with a guess, because a wrong word in a searchable document is worse than no word.

Does the page still look the same?

Yes. The recognised text is added as an invisible layer behind the picture of the page, so the document looks exactly as it did and is now searchable.
