I want the software to have the following features
- resize pictures
- Reduce picture quality
- change pictures format (Example png to jpg)
- Crop the photo
Most of these tasks should be done together
Sorry, my English language is faint

This is actually a Q&A site specific to Ubuntu, if you don't get the answers you need here, it might be best to try asking at the Unix and Linux Stackexchange.
Regardless, Gimp can do all of those tasks, and although I've never tried it in Arch i'm sure it's possible: https://www.gimp.org/downloads/
