About OCR Recognition

PDF OCR recognizes text on scanned PDF pages and produces the extracted content. Tesseract LSTM models run at 300 DPI for accuracy comparable to commercial OCR engines.

Works in multiple languages — drop additional traineddata files into tessdata/ to enable Hindi, Arabic, Chinese, Japanese, and dozens more.

How it works

  1. 1

    Upload the scanned PDF.

  2. 2

    Pick the language pack.

  3. 3

    Get back the recognized text per page.

When to use it

  • Make a scanned book searchable.
  • Recover text from a digitized archive.
  • Pre-process scans before feeding into an LLM.

Privacy

Files are processed by the Evixpdf engine in-house with the AGPL-free MIT stack — no third-party cloud upload. Sessions auto-purge after processing.
