Shrink image file size by adjusting quality, with an instant before/after size comparison. Everything runs in your browser.
FAQ
Are my uploaded images sent to a server?
No. All compression happens entirely in your browser and images never leave your device.
Does lowering quality hurt the image a lot?
Around 70–80 usually cuts size significantly with little visible loss. Check the result preview to judge for yourself.
Can I compress to PNG?
This tool supports JPG and WebP, which compress most effectively. Use the Image Format Converter if you need PNG.
