See Procreate thumbnails on Linux
Wednesday, 4 January 2023
This is old thing I made that I never wrote about here: a thumbnailer for Procreate files. Procreate is a popular iPad drawing and painting app that has its own native *.procreate file format. Most people probably never have to think about this since you can’t access files directly on an iPad and PSD is probably more commonly used for interchange, but it’s pretty straightforward to create thumbnails for Procreate files.
The Procreate files themselves are zip archives and contain a preview image. The thumbnailer just needs to extract the image. Instructions for installing it are in the README file in the linked repo.
