Häufige Fragen
How much smaller will my images get?
Typical savings: 40–70% for JPG at quality 75; 60–90% converting PNG photos to WebP. Line-art and screenshots compress less.
Is it lossless?
JPG and WebP are lossy at the quality setting you pick. PNG re-encoding is lossless but usually only saves 10–20% - for real gains, convert PNG photos to WebP or JPG.
Are images uploaded?
Never. Compression runs in your browser via the Canvas API. Files stay on your device.
Should I use WebP or JPG?
WebP is 25–35% smaller than JPG at the same visual quality and is supported by every modern browser. Use JPG only when a legacy tool requires it.
