FAQ
How much can I compress an image?
Most JPGs can be compressed 60–80% with no visible quality loss. PNGs typically shrink 30–60% via re-encoding to optimized JPG or WEBP.
Is compression lossless?
We offer both. Choose lossless for PNG/WEBP or set a target file size for smart lossy compression.
Do you compress images on a server?
No. Compression runs locally in your browser — your files are never uploaded.
Can I compress to a specific KB?
Yes. Enter a target size (e.g. 100 KB) and the tool binary-searches the best quality that fits.
