256The current dimensions appear as soon as it loads.
With the ratio locked, filling in one gives you the other. Unlock it to set both independently.
Or pick a preset if you are targeting a common size.
Typing a width gives a proportional height, so images do not end up stretched by accident.
Instagram, Full HD, 4K, thumbnails and avatars are one tap rather than remembered numbers.
Resizing uses the browser’s smoothing, which keeps downscaled images sharp instead of aliased.
Set an exact width or height and the other dimension follows automatically, or unlock the ratio to stretch to a specific size. Percentage scaling is there for when you just want something half as large, and presets cover the sizes people actually need — social posts, Full HD, thumbnails and avatars. The original dimensions stay on screen throughout so you can see what changed, and resizing happens on your device with no upload.
