GIF files
GIF is one of the core image formats File Juicer extracts. It supports simple transparency and, unlike JPEG or PNG, can store multiple frames, making it the standard format for short looping animations.
Where File Juicer finds GIF files
Browser caches
The most common reason to extract a GIF is recovering an animated image seen while browsing. Browsers cache everything they download, including animated GIFs. File Juicer can pull them from the Safari cache or Chrome cache complete with all animation frames intact.
Web archives
Pages saved as Safari webarchives or MHT files (Internet Explorer) bundle all images including GIFs into a single file. File Juicer can extract them.
Office documents and email
Word, PowerPoint and older HTML-based email newsletters frequently embed GIF images. File Juicer can extract them from documents and from EMLX email archives.
App bundles and EXE installers
Older macOS and Windows applications used GIF files for interface graphics and loading animations before PNG became dominant. File Juicer can extract them from app packages and Windows EXE files.
Animated GIF
File Juicer extracts animated GIFs as complete files with all frames are preserved. If you only need a still image from an animated GIF, Preview on macOS can open it and export a single frame.
GIF vs PNG
GIF is limited to 256 colours per frame, which makes it unsuitable for photographs. For still images, PNG is the better choice as it is lossless, supports full colour and compresses better. GIF remains useful only for animation; for new animated content most modern platforms prefer AVIF or WebP.
