OCRmyPDF is pure Python, and runs on pretty much everything: Linux, macOS, Windows and FreeBSD. In addition to the required Python version (3.8+), OCRmyPDF requires external program installations of Ghostscript and Tesseract OCR. Please report issues on our GitHub issues page, and follow the issue template for quick response. Our documentation is served on Read the Docs. Once OCRmyPDF is installed, the built-in help which explains the command syntax and options can be accessed via: ocrmypdf - help On Windows, if PATH does not provide a Tesseract binary, we use the highest version number that is installed according to the Windows Registry. It will automatically use whichever version it finds first on the PATH environment variable. You can then pass the -l LANG argument to OCRmyPDF to give a hint as to what languages it should search for.
