img2pdf: Lossless Image to PDF Conversion

img2pdf is a Python library designed for lossless conversion of raster images to PDF. It excels at embedding JPEG and JPEG2000 files without re-encoding, preserving original quality and minimizing file size, treating PDF primarily as a container format. For other image formats, it uses lossless zip compression. The current version is 0.6.3, and the library maintains an active release cadence with regular updates.
