- Phone photos (JPG) — reduced by 60–80% with no visible difference
- PNG screenshots — reduced by 40–60%
- PNG logos — reduced by 30–50%
- Converting to WEBP — additional 25–35% smaller than JPG
Is Compressed Image Quality Good Enough?
Yes. For web and social media use, compressed images look identical to the original on any screen. The human eye cannot detect the difference at typical compression levels. Professional photographers may notice slight differences at 1:1 zoom, but for everyday use the quality is perfect.
