Frequently Asked Questions
What is OCR and how does it work?+
OCR (Optical Character Recognition) reads image-based text from scanned PDFs and converts it into actual searchable, selectable text content.
Can I copy text from the output PDF?+
Yes. After OCR processing, the text in the PDF becomes selectable and searchable — you can copy text, search with Ctrl+F, and the content is indexable by search engines.
What languages does the OCR support?+
The OCR engine supports English and many other major languages. Results are best for clearly scanned documents with good contrast.
How accurate is the OCR?+
Accuracy depends on scan quality. Well-lit, high-resolution (300 DPI+) scans produce very accurate results. Blurry or low-contrast scans may have more errors.
Is the OCR tool free?+
Yes. Completely free with no signup and no upload to any server.
