Any better compression than UIImageJPEGRepresentation?

[anhnch]

I think UIImageJPEGRepresentation is not a good compression. Any chance using other compression methods, such as imagemin, mozjpeg, to get a better quality and file size.

In my app, I try to upload photos to firebase. I have to keep quality as 1 and upload to firebase. Then I implement a trigger in firebase functions to compress and replace the file. This is NOT good at all!

If we can somehow compress better, we don't have to upload a big file and don't have to compress at the server side. Thank you.
