What is a JAM file?
A .JAM file is primarily a collaborative whiteboard project file created by Figma FigJam. These files store diagrams, text, shapes, and sticky notes used for team planning. However, the .JAM file extension is also used by other software. It can be a game resource file for classic Sierra On-Line games, a game data archive for Grim Fandango, an audio session recording for Line 6, or an Apple GarageBand session file. Hardware developers also use it as a Jam STAPL File for programmable logic devices from Altera.
How to open JAM files?
Because .JAM has multiple possible meanings, you must identify the correct software to open your specific file. For standard whiteboard files, you can import them directly into Figma FigJam. If the file belongs to an old game, you might need an extraction tool or an emulator like ScummVM.
viewer.online/Using jam
viewer.online/jam analyzes .JAM files to identify their exact format and creator software, shows which programs can open the file, and usually previews it directly in your browser. Because a .JAM file has multiple possible meanings, we recommend using viewer.online/jam to identify the actual format of your specific file.
Summary
Modern .JAM files from Figma use the known ZIP format. Because of this structure, viewer.online/jam can safely open and display them online, eliminating compatibility problems.
