$ cat FAQ.md
How does compression work?▶
Images are re-encoded using the browser's Canvas API at your chosen quality level and output format (JPG, WebP, or PNG). Lower quality = smaller files.
Are my images uploaded?▶
No. All processing runs in your browser. Nothing leaves your device.
Can I resize while compressing?▶
Yes. Set a maximum width and images wider than that will be scaled down proportionally.
Which format gives the smallest files?▶
WebP typically produces the smallest files at equivalent quality, followed by JPG. PNG is lossless and usually largest.
