Tips for better results
- Around 70-80% quality is the sweet spot for photographs: files shrink dramatically while differences stay invisible at normal viewing size.
- Resize before you compress. Halving the pixel dimensions of an oversized photo saves more than any quality setting can.
- Screenshots and graphics with flat colour compress better as PNG or WebP than as JPG.
