FAQ
How much can I compress an image?
Most photos shrink by 60-90% with no visible quality loss using JPG at 75-85% quality, or by another ~30% on top of that converting to WebP.
Does compressing reduce quality?
At 80% quality the change is invisible on most photos. Below 50% you'll start to see artifacts in flat color areas (sky, walls).
Can I compress a PNG without losing quality?
PNG is already lossless. To shrink it further, convert to WebP — which preserves transparency and visual quality at a fraction of the file size.
Is my image uploaded anywhere?
No. Compression runs entirely in your browser using HTML5 Canvas. Your image never leaves your device.
