The default photo format of iPhones. If that's important. Support was added to imagemagick a year-or-so ago.
In imagemagick, a HEIC image of quality "75" is approximately the same file size as an image of JPEG quality "95".
For the same quality "number", HEIC images are often larger than their JPEG equivalents, which can be confusing if you assume the number directly indicates a "quality" level, which it apparently doesn't.

- zebracanevra 4y agoEven though there's no consensus, there are a bunch of great metrics that are in use such as Butteraugli. I believe JPEG-XL uses it. In JXL the quality setting has been tuned especially well to give predictable speed/visual quality output.
