https://www.change.photos

Built an API to transform photos programmatically (resize, compress, sharpen, blur, rotate, grayscale, format conversion) with single HTTP calls. All tools are free to use (www.change.photos/tools), capped at 2-4MB file sizes, while the API offers 50 images/month on free tier - mainly for those needing to automate image processing at scale.

Background: I used to use Photoshop to resize images without cropping and optimized them that way. But there is no way to do this programmatically, so I got tired.

Zapier also doesn't have great tools for it, and the only one that is there is f*ed and doesn't work for me.
