How to compress an image

What quality should I use?

Why compress images?

Smaller images make pages load faster โ€” better user experience, better SEO, less bandwidth. A photo straight off a phone is often 3โ€“8 MB; compressed for web it can be 200โ€“500 KB with no visible difference.

Frequently asked questions

Is my image uploaded?

No โ€” compression runs entirely on your device. Nothing is sent to any server.

Does it work with PNG?

Yes โ€” PNGs are re-encoded as high-quality JPEG for maximum savings (transparency becomes white). To keep transparency, use the Image Converter to WebP.
