How to OCR a scanned PDF into text

To OCR a scanned PDF, open OCR PDF to Text and select your file. The tool processes the document page by page in your browser, showing the page count and progress so you can confirm the right file and watch it work. When OCR finishes, the combined text is ready to copy or download as a single TXT file.

Because everything runs locally, the source PDF never leaves your device. That makes the tool a safe choice for receipts, contracts, and other personal or work documents that you would rather not send to a remote server just to read the text.

  • Open OCR PDF to Text and select one scanned PDF
  • Let the browser run OCR page by page
  • Review the combined recognized text
  • Copy the text or download it as one TXT file

When to use OCR instead of direct extraction

A scanned PDF is a different job from a simple image OCR pass. People often have a multi-page receipt bundle, exported scanner output, or photo-based document PDF and need all the text out without rebuilding the document itself. OCR PDF to Text is built for exactly those image-based files.

If a PDF already contains selectable text, OCR is usually slower than a direct text extraction, so a plain PDF-to-text tool is the better choice there. Reach for OCR when the pages are scans or images with no selectable text underneath.

  • Scanned PDFs that need editable text
  • Receipt and admin document bundles exported as PDF
  • Image-based reports or forms with no selectable text
  • Quick extraction for notes, archives, and document cleanup
Tips

Getting a better result out of OCR PDF to Text

Specific settings and thresholds, not general advice.

  • Use this when plain extraction returns nothing: OCR reads the pixels, which is the only option for a scanned PDF.
  • The engine recognizes English. Other alphabets will produce nonsense rather than an error, which is the confusing part.
  • Scan quality decides accuracy far more than anything you can set here. 300 DPI, straight, well-lit pages recognize well; a phone photo of a page at an angle does not.
  • OCR is slow because it is doing real work per page. A long document takes minutes, and that is normal.
  • Always proofread numbers. OCR confuses 0 with O and 1 with l, and those are exactly the characters you least want wrong.
Limits

What OCR PDF to Text does not do

The honest boundary, so you do not lose time finding it yourself.

  • It recognizes English only.
  • It does not preserve layout, columns or tables.
  • Accuracy depends on the scan; poor scans give poor text.
  • Handwriting is not reliably recognized.

Files & formatsSearchable PDFA searchable PDF is a scanned document that has a hidden, selectable text layer added by OCR (optical character recognition) beneath the page image. You see the original scan, but you can search, select, and copy the recognized text — unlike a plain image-only scan.General

FAQ

Common questions

Short answers for the questions people usually have before trying a utility like this.

Is OCR PDF to Text free?

Yes. OCR PDF to Text is completely free, with no signup, and the OCR runs entirely in your browser.

Does this upload my PDF to a server?

No. OCR PDF to Text runs the recognition locally in your browser, so the source PDF stays on your device during processing.

Which PDFs work best for OCR here?

Scanned or image-based PDFs work best. If the PDF already contains selectable text, a direct PDF-to-text extraction is usually faster than OCR.

Can I copy or download the text after OCR finishes?

Yes. Once OCR completes you can review the combined text, then copy it to your clipboard or download it as a TXT file.

Does it work on mobile?

Yes. OCR PDF to Text runs in any modern browser, including on phones and tablets, with nothing to install.

What languages does the OCR support?

English. The recognition engine is loaded with the English model, so other alphabets produce plausible-looking nonsense rather than an error, which is worth knowing before you trust the output.

Why is the OCR so slow?

Because it is recognizing every character on every page, in your browser. A long scan takes minutes; that is the work, not a stall.

How can I improve the accuracy?

Improve the scan. A straight, well-lit page at around 300 DPI recognizes well. A skewed phone photo does not, and no setting compensates for it.

Why are the numbers wrong?

OCR confuses 0 with O and 1 with l. Always proofread digits: they are the characters where a mistake costs most and looks least obvious.

Do I need OCR at all?

Only if the PDF is a scan. Try the plain text extractor first: if it returns text, that text is exact, and OCR would only introduce errors.

Is my scan uploaded to an OCR service?

No. The recognition engine runs in your browser, which is unusual for OCR and matters for documents you should not be sending anywhere.
