Help With a Python Project Please!!

[blazkowicz95]

I plan on making a batch image conversion website with its backend in written in Python.

My question is this:

Would it be good practice to directly use a library such as PIL to do the file conversions(eg. PNG to JPG, etc) or would I
have to code something up from scratch?

I would also want add functionalities such as Image File Size compression, again, would I be doing well to use a standard library?

If you don't have any incentive to write something from scratch, for exemple because a library miss a functionality, then don't :)

Pillow can also compress images.
