Spine 2D Viewer

Preview Spine skeletal animations in the browser — play animations, switch skins, scrub the timeline.

Drop .json, .atlas, and .png files here

What you need

Spine exports a character or object as three related files. Upload all of them together to preview animations, switch skins, and capture screenshots — no Spine Editor required.

  • .json skeleton dataSpine JSON export with bones, slots, skins, and animation keyframes. Export from Spine Editor via JSON format (not binary .skel).
  • .atlas texture mapText file listing texture regions and their coordinates on the image page(s). Generated automatically when exporting from Spine.
  • PNG texture page(s)One or more images referenced by the .atlas file. If the atlas lists multiple pages, upload every PNG file.

Files are matched by name (e.g. hero.json, hero.atlas, hero.png). Spine 2.x/3.x JSON is upgraded automatically; 4.x JSON works natively.
