How to get the smallest file that still looks good
Most of a photo's size comes from its dimensions. A phone takes 4000 px wide photos; a screen rarely shows more than 2000 px, so scaling down to 2048 px cuts the file by more than half before quality even matters.
Then quality: 75% is the usual sweet spot for photos. WebP gets another 25 to 35% smaller at the same look, if the place you're uploading to accepts it.
Frequently asked questions
Can I compress a PNG?
Yes. Convert it to JPG or WebP for the biggest saving; PNG output is lossless, so only a smaller size reduces it.
Are my files uploaded anywhere?
No. The conversion runs inside your browser on your own device. The files are never sent to a server, so nobody else can see them, and they're gone when you close the tab.
Is it really free?
Yes: no sign-up, no watermark, no daily limit and no ads. Because the work happens on your device, there are no server costs to pass on.
