Feedback Form: Can I compress an attached file when sending it?

Question

PHP

There is a quite standard feedback form with a handler in php, with the ability to attach up to ten files (photos). Everything works, the question is: is it possible to compress files (reduce the size of the resulting file) attached by the user at the handler stage? It is clear that you can specify the maximum file size, but this is a bit not what you need.

Answer 1

If you are interested in choosing the optimal method - decide on the minimum allowable sizes for normal image recognition and cut to them, play around with the compression quality parameter.
If you are more interested in the resizing algorithm itself - Google to the rescue, choose the library you like the most - and go ahead.

Answer 2

A fileinput plugin that can reduce photo size should work.
