Resize image to 400x400 online free — Free & Private
Upload JPG, PNG, WEBP, or GIF and download exactly 400×400 pixels (square). This page locks 400×400 in the sidebar — no manual typing required. A 400x400 export (square) fits app store icons, game assets, and square social avatars.
After upload, confirm the sidebar shows 400 and 400. PNG files download as PNG; other inputs save as high-quality JPG. When composition matters, crop to square first, then return here for the exact 400x400 export.
If a portal also caps file size, run a compress pass after resizing. For dimensions outside 400x400, use the main Resize Image hub on Rankify.
