What the Image Resizer does
The image resizer changes the dimensions of your images to the exact pixel size you need, without uploading them anywhere.
How it works
The tool draws your image onto a canvas at the new dimensions and exports the result. You can set width and height independently or lock the aspect ratio to avoid distortion.
Resizing images to the size they are displayed at avoids wasting bandwidth on oversized files, which speeds up your pages.
