Image Resizer

Scan to open this page

Resize an image to exact pixels or a percentage — aspect ratio is locked by default so you can't accidentally stretch a circle into an oval, unlike tools where that protection is an easy-to-miss opt-in toggle.

How it works

  1. Upload an image
  2. Enter a target width or height in pixels (or a percentage) — aspect ratio locks the other dimension automatically
  3. Download the resized PNG or JPG

Frequently asked questions

Why is aspect ratio locked by default?

Many resizers make you remember to enable a "lock aspect ratio" option — forget it and circles become ovals, faces stretch. This tool locks it by default; uncheck it only if you deliberately want a different ratio.

Will resizing up (enlarging) lose quality?

Yes — enlarging past the original pixel dimensions always loses some sharpness, since there's no extra detail to invent. Downsizing preserves quality far better.

Does my photo get uploaded to a server?

No — resizing happens entirely in your browser using the Canvas API.

"Lock aspect ratio" shouldn't be a checkbox you have to remember. So it isn't, here.

"Lock aspect ratio" shouldn't be a checkbox you have to remember. So it isn't, here.

Forget to enable it on most resizers and circles become ovals, faces stretch. This one locks aspect ratio by default — you have to deliberately turn it off to distort an image.
