What is Image Resize?

Image Resize scales images to a target width / height while keeping aspect ratio if you choose. Useful for preparing avatars, thumbnails, or fitting platform-specific upload limits.

How to use Image Resize

  1. Drop one or more images.
  2. Enter target width / height (lock aspect ratio if you want).
  3. Click "Resize" — Canvas API redraws each image at the new size.
  4. Download the resized images.
