Best Free OCR Tools in 2025
Need to extract text from scanned PDFs, old documents, or images? Here's a comparison of the best free OCR tools available today.
The Problem: Locked Text in Documents
Millions of documents exist as scanned PDFs or images - old books, historical records, business documents, and academic papers. The text is trapped and unsearchable. You can't copy it, translate it, or edit it. This is especially challenging for:
- Arabic documents - Right-to-left text requires specialized OCR
- Urdu and Farsi texts - Complex scripts with connected letters
- Chinese and Japanese - Thousands of characters to recognize
- Old scanned books - Poor quality, faded text, yellowed pages
- Multi-page PDFs - Processing hundreds of pages manually is impossible
The Solution: Modern OCR Technology
OCR (Optical Character Recognition) technology has advanced dramatically. Modern tools can now:
- Extract text from any language with 95%+ accuracy
- Process multi-page PDFs in seconds
- Handle poor quality scans and handwritten text
- Preserve formatting and layout
- Work entirely online - no software installation needed
