Do we have any parameter / flag for pdf compression here, to reduce pdf size after applying OCR? #48

Hello @yatrik-cloud. There's no such flag for PDF compression. But you can emulate it using image processing ("-f") and some image reduction strategy. First, please use "-f" and "-r 200" to reduce image resolution and this should reduce size. Also, try to play with "-g" parameters.

"-f" is changing pdf image color, a gray scale image to black/white binary image

Yes, this is expected. That’s why you should use “-f” combined with some “-g” option.

Old issue, marking as done due to lack of response.
