Why compress images?

Large photos slow down websites, eat mobile data and hit email attachment limits. Compressing at quality 80 typically cuts file size by 60–80% with no visible difference.

Format tips

Use JPEG for photos, WebP for the web (30% smaller than JPEG), and PNG only when you need transparency or pixel-perfect graphics.

Upload JPG, PNG, WebP or GIF (first frame); export as JPG, PNG or WebP.

What quality should I choose?

80 is the sweet spot for web photos. Go lower (60) for thumbnails, higher (90+) for print.
