What is a .Skel file?
SKEL is the binary skeleton data for a Spine 2D animation.
- Did you know
- SKEL stores the bones and animations of a Spine character compactly.
- The binary .skel export is far smaller and loads faster than Spine’s equivalent JSON skeleton data.
- Spine reads the skeleton through its runtimes, which support dozens of game engines and programming languages.
- What Analyser reads
- Identify and read more game and emulator files: Unity asset bundles, Unreal cooked assets, CISO/CHD disc images, FMOD/Wwise sound banks, Spine skeletons and atlases, GameMaker/LDtk/TIC-80 projects, Minecraft Anvil regions, Warcraft III maps, Ren Py and RPG Maker data, extra console ROMs (Atari, PC Engine, Master System/Game Gear, WonderSwan, 3DS homebrew), xdelta/Basis patches and emulator saves and movies.
- Depth of analysis
- .Skel is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .Skel file
- Drag a .Skel file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
