Alferd Spritesheet Unpacker — Quick Guide & Download
What it is
Alferd Spritesheet Unpacker is a utility that extracts individual sprite images and metadata from spritesheet/container files used by games or animation tools. It automates slicing by reading sheet layouts or embedded frame data, producing separate PNGs plus optional JSON or XML frame descriptors.
Key features
- Batch unpacking of multiple sheets
- Support for common sheet formats (PNG-based atlases, some engine-specific containers)
- Export of frame metadata (coordinates, pivot, duration)
- Optional trimming and alpha-preservation
- Command-line and GUI modes (if provided by the release)
Quick usage (GUI)
- Open the application.
- Add one or more spritesheet files via drag-and-drop or File → Open.
- Choose output folder and format (separate PNGs, JSON/XML).
- Set options: trim transparent borders, preserve original names, retain pivot data.
- Click Export / Unpack.
Quick usage (CLI example)
Code
alferd-unpack -i spritesheet.png -o ./output –format json –trim
(Adjust flags to match the actual tool; check the included README or help output.)
Common formats & compatibility
- Simple PNG atlases with a separate metadata file (JSON/XML)
- Engine-specific packs (may require plugin or converter)
- Animated container formats—may export frame order and durations
Troubleshooting
- If frames overlap or are misaligned: try enabling automatic grid detection or provide an accompanying metadata file.
- Transparent edges lost: ensure “preserve alpha” is enabled.
- Unsupported container: check for available converters or export from the original engine.
Where to get it
