This is an old question, but on Windows, on Mac and on Linux, you can extract images from PDF (without recompressions) with different multi-platform tools: 1) pdfcpu > pdfcpu extract -m image in.pdf . 2) pdfimages > pdfimages -all in.pdf page 3) mutool > mutool extract in.pdf 4) img2pdf, that has been already mentionner for Linux, exists also for Windows and MAC (it's a Python script).

I would like to script the following action : 1) import multiple images from pattern (like page*.png) 2) convert all images to black ans white with threshold 700 3) save the resulting images in a single pdf (with ccitt compression) Is it possible to achieve this steps with the cli ? (I know how to do it with the GUI) Thanks in advance for your help.

I would like to advocate for this feature. PDF supports jpx (i.e. jpeg200 streams). And the quality of jpeg2000 for the same file size is much higher, compared to jpeg (even to files compressed with mozjpeg). You can check this assertion for exemple in this comparison page.

Use mozjpeg for jpeg compression
