Good to know
512 by 512 is the standard for app icons, web manifest icons and most avatar uploads.
For a browser tab icon, the favicon generator makes the whole set at once instead.

Common questions
Is the resizer free?
Yes, properly free. No paid tier, no trial, no watermark on the result and nothing to sign up for. Put as many files through it as you like, as often as you like.
Are my files uploaded to a server?
No. The resizer runs inside your browser, on your own machine, so your files never go anywhere. Big ones are fine too, up to whatever your browser can hold.
Will my photo be cropped to fit 512 by 512?
Yes, if it isn't already that shape. The image is scaled until it covers the whole frame and the overflow is trimmed off, which keeps everything in proportion rather than stretching it. The middle is what survives, so if the important part is off to one side, crop it yourself first and then come back here.
What if my image is smaller than 512 by 512?
It gets enlarged to fit, and enlarging always costs sharpness, because the extra pixels have to be invented from the ones already there. It will still be exactly the right size, it just won't be as crisp as the same picture from a larger original. Start from the biggest version you have whenever you can.
