Because, PDF is a container, like a fancy zip, the pictures saved in are kept in their original format, (JPEG, PNG/APNG, AVIF, GIF, JP2k, JPXL, BMP…) unless you add a step to re-compress the all document with image.
It’s always slightly bigger than the original file.
interesting. but what if i want to make a mixture of vector graphics with a small portion raster graphics. the PDF would probably be smallest, because it will store all the vector graphics as vector graphics and only the small part raster graphics as raster graphics.
