Yes, by far my top choice in OSS land for image manipulation. You would probably want to couple it with a edge worker to do things like accept handling (what format to return for the same url), whitelisting formats and so on.
I wrote a pretty comprehensive cloudflare worker for this years ago I should look at open sourcing..
Please do open source it!
Kind of curious that the images on that site are completely messed up/misaligned on mobile.
