Image Resizer od Chandler Stimson

A powerful image resizer that can rescale multiple images into multiple sizes at once in pixel or percent units. The extension supports storing and retrieving jobs for easy resizing.

Although the resizing is a lossy conversion, the extension tries to keep the quality of the resized images as much as possible by down-sampling when scaling to smaller sizer and interpolation when scaling to the larger sizer.

The extension supports storing scaled images in PNG, WebP, and JPEG formats, and the quality of each job can be configured separately.

This extension supports custom canvas size and a custom background color for resized images to fine-tune your final image size without scaling the actual image.
