What is the best free OCR tool?

PDFJolt is the best free OCR tool for privacy — it runs Tesseract.js in your browser with no uploads. Google Cloud Vision has the highest accuracy but requires developer setup. For desktop use, Tesseract is the leading open-source OCR engine.

Can OCR extract text from handwriting?

Some OCR tools can read handwriting. Google Cloud Vision and ABBYY FineReader handle handwriting best. PDFJolt and Tesseract have basic handwriting support. Accuracy depends on handwriting legibility and quality of the scan.

Is free OCR accurate enough for professional use?

For typed text and clear scans, free OCR tools like PDFJolt achieve 90-98% accuracy. Complex layouts, poor scans, or handwritten text may require professional tools like Adobe Acrobat or ABBYY for best results.
