OCR a scanned PDF to searchable text — free
Guide · 4 min read
A scanned PDF is really just photos of pages — you can't search it, copy
from it, or let screen readers read it. OCR (optical character recognition)
fixes that by adding an invisible text layer under each page image. The scan
still looks identical, but now Ctrl+F works.
Open OCR PDF — free
Step by step
- Open the OCR PDF tool.
- Drop in your scanned PDF.
- Run it and download the result — same-looking pages, now searchable.
- Test it: open the PDF and search for a word you can see on the page.
Getting the best OCR results
- Resolution matters. 300 DPI scans OCR beautifully;
blurry phone photos of pages won't.
- Straighten first. Skewed pages confuse OCR — fix rotation
with Rotate PDF before running OCR.
- Print, not handwriting. Printed text converts
accurately; cursive handwriting mostly doesn't.
- Photos of two pages? Split them first with
Scanner Image Split.
After OCR, you can pull the text out entirely with
PDF to Text — or convert the scan to an
editable document with
PDF to Word.
Frequently asked questions
- What does OCR do to a scanned PDF?
- It reads each page image and adds an invisible text layer — the document looks identical but becomes searchable and copyable.
- Can OCR read handwriting?
- Printed text works very well. Handwriting is hit-or-miss — neat block letters may come through, cursive usually doesn't.
- Is it free?
- Yes — free with no sign-up and no watermark.
