How to resize images

Which size to choose
1280 px is plenty for email, chat and most upload forms. 2048 px suits websites and social media. 3840 px matches a 4K screen.
Images smaller than the chosen size are left as they are; nothing is ever stretched up.
Frequently asked questions
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.
