Image Resizer

Resize JPG, PNG and WebP images to exact pixel dimensions or scale them by percentage. Aspect ratio is preserved by default, and you can choose the output format.

Keeps proportions; when both width and height are set, the image fits inside them.
If set, width and height are ignored. 50 = half size, 200 = double.

How to use this tool

  1. Click “Choose File” and select an image.
  2. Enter a width, a height, or a percentage — or fit inside a width × height box.
  3. Leave “Maintain aspect ratio” ticked to avoid distortion.
  4. Pick an output format (or keep the original) and press “Resize image”.
  5. Download your resized image.
