The GIM file extension is used by Sony’s portable PlayStation Player (PSP) gaming device. GIM files store images supporting 256 colors and alpha channels. They are commonly found within PSP Theme Files with the .PTF extension.
There are 522 file types with the .GIM extension, but most are incompatible. The GIM format was originally developed for Sony’s GimConv application. Files named PlayStation Portable Image Format are often edited in GimConv.
To work with GIM files, you can use GIM file openers, converters, viewers or editors. Another option is GIMP – the GNU Image Manipulation Program. This free software handles photo editing, image composition and authoring.
When sharing GIM files, instructions should be provided on compatible editing, converting and printing software. This assists users in handling these file types properly.
