Reply to comment by Luthemplaer in ELI5: In recent years, new formats like webp and jfif have started popping up. However, if I rename them to gif or jpeg, they still work. How can it be that renaming the extension doesn't ruin the image format? Why do they even exist then? by Luthemplaer

Upgrade to Photoshop 2021 (v22) or Photoshop 2022 (v23). What you're describing is a known bug in older versions of Photoshop. Photoshop 2020 and Photoshop 2019 had a bug where they could only open .jfif files if they were incorrectly renamed as .jpg.
