In my last project managed to bring my Linux web server to a complete halt when trying to transform a dozen of high resolution HEIC images on the server side, it just didn't work. I couldn't find a good existing solution to my problem. The existing services I found were usually offering too much, like integration with their CDNs which didn't align with privacy requirements of my project. I needed a very simple and very performant service to do this 'one thing'. That is why I developed a service based on Apple's CoreImage library which runs on Apple Silicon and MacOS. The benchmarks were great, to convert a single 12 megapixel HEIC image on Linux it took 5s and on Apple Silicon it was below 100ms. I thought other people might run into the same problems as I did, that's why I made the service as an API for others to use as well. It is my first SaaS project put into the 'wild' :)
