How do I open a .SPRITEATLAS file?

Drop a .SPRITEATLAS file onto Analyser at https://lab.valjdakosta.com/ and it opens directly in your browser - no upload, no account and no software to install. Open Unity game-engine assets in the browser. Unity serialises scenes (.unity), prefabs, Animator Controllers (.controller), animation clips (.anim), materials (.mat), physics materials (.physicsMaterial2D) and other assets (.asset) as a YAML object stream, with a .meta importer record (carrying the asset GUID) beside every file. Analyser splits the object documents and reads each - a scene's GameObjects and component-type breakdown (Transform, SpriteRenderer, colliders, scripts), an animation's sample rate and curves, a controller's layers and states, a material's friction and bounciness, and a .meta's GUID and importer.

Can I open a .SPRITEATLAS file online for free?

Yes. Analyser is a free online .SPRITEATLAS opener and viewer that runs entirely in your browser - your .SPRITEATLAS file never leaves your device, so there is nothing to upload and no software to install. It even works offline once installed.

What is a .SPRITEATLAS file?

SPRITEATLAS is a Unity sprite atlas - a packing of many sprites into one texture to cut draw calls. Created and opened by Unity.

Did you know: Packing sprites together lets the GPU draw them in a single batch, a classic 2D performance win.
Analyser handles .SPRITEATLAS alongside related formats such as .UNITY, .PREFAB, .ASSET and more.
In Analyser's format library, .SPRITEATLAS sits in the Games category.
