I'm working building a site to sell shoes, and I have at least 34K pictures in one of my HDD I want to upload these pictures to the shopping site, but they need to be compressed first (lossy compression) like on TinyPNG
The question is:
Is there a program like that?
For example feed the software a folder with the pictures and the program does the compression and outputs the files or a folder with the images already processed
A free software would be super useful too.
