How to Make a Scanned PDF Searchable with OCR
Turn a scanned, image-only PDF into a searchable, copyable document using OCR — in a few clicks, in your language.
Short answer: Open the OCR tool, upload your scan, select the document language, and download a PDF you can search and copy from. Pages that already contain text are skipped automatically.
A scanned PDF is really just a picture of a page — you can't select the text or find anything with Ctrl+F. OCR fixes that by recognizing the characters and adding a searchable text layer behind the image.
How to OCR a PDF
- Upload your scanned PDF to the OCR tool.
- Choose the language of the document for the best accuracy — or select the automatic option if you're unsure.
- Download the searchable PDF.
Why choosing the right language matters
OCR engines use language-specific models to recognize letters and words. Selecting the correct language:
- improves accuracy on accented characters (ç, ş, ü, é, ñ…),
- reduces misread words,
- and is faster than running every language at once.
If a document mixes languages, the automatic option runs all installed languages together.
What OCR does — and doesn't do
- ✅ Makes scanned/photographed PDFs searchable and copyable.
- ✅ Keeps the page looking exactly the same.
- ✅ Skips pages that already have real text.
- ❌ Does not convert the PDF into an editable Word file — use a PDF-to-Word tool for that.
Good scans give better results
For the sharpest text recognition, scan at 300 DPI, keep pages straight, and avoid shadows. The cleaner the image, the fewer mistakes OCR makes.
