Features
- Side-by-side — original vs compressed, click to enlarge at full resolution
- Format — JPEG, WebP (lossy), PNG (lossless). Auto-selects best format.
- Quality slider — 10–100%, live preview updates
- Resize — cap max dimension before compressing
- Target size — set KB limit, auto-finds right quality
- Compare Formats — table of all formats at 7 quality levels
- Same-format warning — warns when output matches source (e.g. PNG→PNG)
Tips
- WebP is usually 25–35% smaller than JPEG at same quality
- Resizing a 4000px photo to 1920px saves more than any quality slider
- Quality is in the filename:
