What settings should I use?
| Use | Quality | Max size | Format |
|---|---|---|---|
| Website or blog | 70–80% | 1920 px | WebP |
| 70% | 1600 px | JPG | |
| Upload under 200 KB | 50–60% | 1280 px | JPG |
| 90% | Original | JPG |
JPG, PNG or WebP?
JPG is best for photos and works everywhere. WebP is usually 25–35% smaller than JPG at the same quality and works in all modern browsers. PNG keeps transparency and sharp text but makes large photo files. If you choose Keep best format, PNG photos are saved as WebP to keep transparency at a smaller size.
Private and unlimited
Online compressors usually upload your photos and cap how many you can do for free. This tool compresses on your own device using your browser's built-in image encoder, so there's no upload, no file count limit and no sign-up.
Questions
How much smaller will my images get?
Phone photos usually shrink by 70 to 90% at the default settings. Images that are already compressed shrink less.
Will it reduce quality?
At 75% or higher the difference is very hard to see. Lower settings show artifacts in skies and gradients.
Is there a limit on files?
No. You can compress as many as your device can handle.
Are my photos uploaded?
No, everything happens in your browser.
