Some users have noticed that current versions of OCRmyPDF do not run as quickly as some older versions (specifically 6.x and older). This is because OCRmyPDF added image optimization as a postprocessing step, and it is enabled by default.


If running OCRmyPDF quickly is your main goal, you can use settings such as:

  • --optimize 0 to disable file size optimization
  • --output-type pdf to disable PDF/A generation
  • --fast-web-view 0 to disable fast web view optimization
  • --skip-big to skip large images, if some pages have large images

You can also avoid:

  • --force-ocr
  • Image preprocessing
