// HOW IT WORKS

The tool compresses images to modern formats (WebP, AVIF) right in the browser — no upload — to shrink file size while keeping quality acceptable.

Example

A 2 MB JPEG re-encoded as WebP at quality 80 often drops to ~300–500 KB.

Notes

AVIF usually compresses best but encodes slower; WebP is a fast, widely supported middle ground.
Lowering quality past ~70 starts to show visible artifacts on photos.
