How to get text from a picture

  1. Choose one or more pictures.
  2. Tick the language (or languages) of the text.
  3. Press Read the text, then copy it, download it, or save a searchable PDF.

For best results

  • Sharp, straight and well-lit pictures read best.
  • Pictures that are sideways or upside down are detected and read the right way.
  • Printed text works much better than handwriting, which is usually not recognized.
  • Small text in small screenshots is enlarged before reading.

Good to know

  • Languages: English, Spanish, French, German, Portuguese, Italian, Russian, Arabic, Hindi and Chinese (Simplified).
  • The text recognition engine is Tesseract, the open-source OCR engine, running in your browser. The first time, the engine and each language you choose (1–4 MB each) take a moment to download.
  • Text recognition is never perfect: check names and numbers that matter.
  • The searchable PDF shows your pictures with invisible text on top, so you can search and copy it.

Câu hỏi thường gặp

Does it read handwriting?

Rarely well. It is made for printed and typed text.

Can I read text from a PDF?

If the PDF already has text, use PDF to Text. For scanned PDFs, use OCR PDF.

Are my pictures uploaded?

No. They are processed in your browser and never sent anywhere.
