Image Compressor

How it works

1. Choose one or more images (up to 30 at a time).
2. Set the quality, and optionally a smaller size or a different format.
3. Click Compress images and download them one by one or all together as a ZIP.

Which settings should I pick?

Quality 70–80% is the sweet spot for photos: a much smaller file with no visible difference on screen.

Resize makes the biggest difference for phone and camera photos. Max 1920 px is plenty for websites, email and upload forms.

WebP gives the smallest files and keeps transparency. Pick JPG when the image has to open everywhere; transparent areas turn white.

Private by design
