A scanned PDF is just a stack of images — you can't search inside it, copy text from it, or get a screen reader to read it aloud. OCR (Optical Character Recognition) fixes that by recognising the printed text in those images and adding a searchable text layer to the PDF.
The OCR PDF tool extracts text from any scanned PDF in seconds. Here's how.
Step-by-step: how to use OCR PDF
- Open the tool. Visit ilovepdf.cyou/ocr-pdf.
- Upload the scanned PDF. Drop your image-based PDF. The tool detects whether OCR is needed automatically.
- Process. Each page is analysed and text is extracted using OCR.
- Download. The result saves as
ILovePDF-ocr.pdf— a searchable PDF with the extracted text. - Search and copy. Open the OCR'd PDF in any reader and use Ctrl+F to search for text.
Why use OCR PDF?
- Searchable scans. Find any word in a 200-page scan instantly with a single text search.
- Copy-paste enabled. Select and copy text directly from a previously image-only PDF.
- Accessibility. Screen readers can finally narrate scanned documents for visually impaired users.
- Powers other tools. OCR'd PDFs work better with Translate, AI Summarizer and PDF to Word.

Pro tips for the best results
1. Higher scan resolution = better OCR
300 DPI scans typically OCR more accurately than 150 DPI scans.
2. Rotate first if needed
OCR works best on upright pages. Use Rotate PDF first if any pages are sideways.
3. Crop borders
Use Crop PDF to trim scan margins before OCR for cleaner text extraction.
4. Combine with AI Summarizer
After OCR, run AI Summarizer to extract key points from the recovered text.
Frequently asked questions
How accurate is the OCR?
Typically 95%+ on clean scans of standard fonts. Handwriting and stylised fonts may have lower accuracy.
What languages are supported?
English is the default. Multi-language support is on the roadmap.
Will it modify my original PDF?
No. The OCR'd copy is a new file with an added text layer.
Is the text 100% editable?
OCR adds an invisible text layer over images — for full editing convert to Word with PDF to Word.
