An Electron desktop app for batch-downloading all your Mixamo animations (FBX) and animated GIF previews, with a built-in Mixamo browser for easy login.
Log in with the embedded browser on the left, pick your rig and output folder on the right, then download every animation in one click.
- Embedded Mixamo browser — log in directly inside the app, token is captured automatically
- Batch FBX download — downloads all animations for your character in FBX 7.0 / 30 FPS format
- Rig variants — pick the skeleton your character uses (Standard 65-bone, 3-chain / 2-chain fingers, or no-fingers 25-bone). Each rig is downloaded into its own
rig_{N}/folder with its own library file, so you can keep multiple bone variants of the same animation side by side - Animated GIF previews — downloads the preview GIF for every animation (including per-animation previews for pack motions)
- Pack support — pack animations are organized into
_Packs/{Pack Name}/subfolders automatically - Auto-reorganize & migration — existing flat downloads are moved into the correct folders on startup; pre-rig downloads are migrated into
rig_25/automatically - Live animation library — builds and updates a per-rig
animation-library-{N}.jsonduring download with full metadata - Duplicate detection — pack animations that are identical to standalone ones are cross-referenced in the library
- README generation — generates
LIBRARY_README.mdin your output folder describing the entire structure

Why rig folders? Mixamo exports animations using the skeleton of the character you have loaded. A character without finger bones produces 25-bone animations; the standard rig produces 65-bone animations with full fingers. The two are not interchangeable, so the app keeps each bone count in its own
rig_{N}/folder and never mixes them. GIF previews are identical regardless of rig, so they are stored once in a shared_GIF/folder.
git clone https://github.com/underfusion/mixamo-downloader.git
cd mixamo-downloader
npm installOr on Windows, double-click install.bat.
npm startOr double-click start.bat.
- Log in — the app opens Mixamo in the left panel. Log in with your Adobe account. The status dot turns green when the token is detected.
- Select your rig — pick the Rig type that matches the character loaded in Mixamo (e.g. Standard Skeleton (65) for a full rig with fingers, No Fingers (25) for a simplified one). Animations are saved into the matching
rig_{N}/folder. Choose Custom… to enter any bone count manually. - Select output folder — click
...next to the output field to choose where to save animations. - Download — click Download all animations. The app will fetch the animation list and download every FBX + GIF.
- Fix GIFs — if you already have FBX files, click Download / Fix GIFs to (re-)download all GIF previews without touching the FBX files.
Tip: To collect the same animations for multiple rigs, load a different character in Mixamo, change the Rig type dropdown to match, and run the download again. The app downloads into a separate
rig_{N}/folder each time — nothing is overwritten.
Mixamo's animation list is cached locally for 24 hours. Click Refresh animation list to force a fresh fetch on the next download.
These scripts can be run independently from the command line:
node scripts/generate-library.mjs [output_dir]
# With API enrichment (fps, loop info):
set MIXAMO_TOKEN=<your_bearer_token> && node scripts/generate-library.mjs [output_dir]node scripts/download-gifs.mjs [output_dir]
# With pack GIFs (requires token):
set MIXAMO_TOKEN=<your_bearer_token> && node scripts/download-gifs.mjs [output_dir]node scripts/reorganize.mjs # dry-run — analysis only
node scripts/reorganize.mjs --move # actually moves filesOne library file is generated per rig (animation-library-65.json, animation-library-25.json, …) and updated automatically during download. The {N} is the bone count. Each file includes:
| Field | Description |
|---|---|
id |
Mixamo product UUID |
description |
Full animation name (used as filename) |
rig_bones |
Bone count of this rig (e.g. 65, 25) |
character_id |
Mixamo character UUID used for the download |
pack |
Pack name, or null for standalone |
fbx_file |
Relative path to the FBX file (includes the rig_{N}/ prefix) |
gif_file |
Relative path to the GIF preview (shared _GIF/ folder) |
fbx_downloaded |
true if the file exists on disk |
gif_downloaded |
true if the GIF exists on disk |
also_in_packs |
(standalone only) list of packs that contain this animation |
standalone_duplicate |
(pack only) reference to the standalone version if it exists |
thumbnail_animated |
CDN URL to the animated GIF preview |
~600 out of ~745 pack animations are identical to standalone animations — same motion, same Mixamo product_id, just grouped into a themed pack. The library cross-references these so you can avoid loading duplicate files:
// Load only unique animations (no pack duplicates) for the 65-bone rig
const lib = JSON.parse(fs.readFileSync('animation-library-65.json'));
const unique = lib.animations.filter(a => !a.pack || !a.standalone_duplicate);- The app caches the animation list in
animations-cache.json(next to the app, not in your output folder) - Download speed is intentionally throttled to avoid hitting Mixamo's rate limits
- The
animations-cache.json,download.log, and your output folder are excluded from git
