Hey guys,

we are two devs who built a free & open source image optimization plugin (GPLv2): neo Optimize

Most image resizing plugins downsize your original image files to some fixed size and you lose the original data forever. We wanted to keep the originals similar to non-destructive editing.

So we built a small free/open-source plugin that tries to solve this by leaving your images as-is and copying a resized version into the cache folder. The image size is determined by the exact size the image is used on your site.

We wanted it to be beautiful, simple, fast, free & open source. There is a Pro version, but the free version is fully usable and does not hard-push upsells.
