You see the real before and after sizes, then save the file straight to your device.
Basic, Balanced and Heavy Compression
Every level trades size against quality differently. Pick the trade-off that fits how you will share the file.
Basic Compression
Gentler settings.
Keeps more detail, so savings are usually smaller.
Balanced Compression
Default balance.
Usually the largest saving you can take without obvious quality loss.
Heavy Compression
Most aggressive.
The smallest practical file, with more visible quality loss.
