FAQ
Frequently asked questions
What is OCR?
OCR (Optical Character Recognition) reads text from images and scanned documents. It converts image-based text into actual, selectable characters that can be searched, copied, and edited.
Is my PDF uploaded to a server?
No. The entire process runs locally in your browser using Tesseract.js, the industry-standard open-source OCR engine originally developed at HP Labs. Your file never leaves your device.
What is a searchable PDF?
A searchable PDF has an invisible text layer placed over the original scanned images. It looks exactly like the original scan, but the text can now be selected, copied, and found with Ctrl+F.
What languages are supported?
English, Spanish, French, German, Italian, Portuguese, Russian, Chinese (Simplified), Japanese, Arabic, Hindi, and Korean.
Can I convert the result to Word?
Yes — click "Convert to Word" after OCR. The searchable PDF is passed directly to the PDF to Word tool, no re-upload needed.
How accurate is the OCR?
Accuracy depends on scan quality. Clean, high-resolution scans of typed text achieve 95%+ accuracy. Handwriting, unusual fonts, or low-resolution scans give lower results.
