Frequently asked questions
How do I resize an image to 400×400?
Drop it in — 400 and 400 are already set — choose Fit or Fill, and download. No manual cropping needed.
Is my image uploaded?
No — resizing happens in your browser and the file never leaves your device.
Where 400×400 is used
400×400 is the standard size for profile pictures and avatars on forums, social platforms and chat apps.
Fit or fill?
Crop to a centred headshot before resizing for the most flattering avatar, then use "Fill" to lock in the exact square.
Need a different size? The image resizer accepts any custom width and height.
