How Image Resizer works

Resize by entering a width, a height, or both. When only one dimension is supplied, GuavaPix preserves the original aspect ratio so the image does not look stretched.

How to use it

  1. Choose or drop a supported image.
  2. Adjust the available controls, then process the image.
  3. Check the output size and download the new file.

Frequently asked questions

Does resizing change the aspect ratio?

Not when you provide one dimension. GuavaPix calculates the other dimension from the original image ratio.

Are my images uploaded?

No. Processing happens locally in your browser and the image is not sent to GuavaPix.
