Frequently asked questions
Which languages does the OCR support?
English, French, German, Spanish, Italian, Portuguese, Arabic, Russian, Chinese (Simplified), and Japanese. Select your language before running for best accuracy.
My PDF already has selectable text - do I need OCR?
No. OCR is only for scanned or image-based PDFs where the text is a photo, not real characters. If you can already highlight text in your PDF reader, OCR is not needed.
How accurate is the OCR?
Accuracy depends on scan quality, font clarity, and language complexity. Clean, high-resolution scans of printed text typically achieve 95%+ accuracy. Handwriting, decorative fonts, and low-resolution scans will be less accurate.
