image-to-png skillA
image-to-png is agent-read markdown (skill) from godot-fun/godot-agent: Converts image files to PNG using FFmpeg while preserving dimensions and alpha. Use when the user wants to convert images to PNG, transcode JPG/WebP/GIF/BMP/TIFF to PNG, export a game/UI texture as PNG, or mentions PNG conversion without background removal..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Image to PNG
Convert a **single image file** to **lossless PNG** via FFmpeg. **Defaults preserve source quality** — dimensions unchanged, alpha channel kept when present.
## Rules
When this skill applies, read and follow [skill-dependency-manager](../skill-dependency-manager.md) — run scripts as documented, install missing tools into `.dependency/`.
- Run `convert.py` through the bundled script — do not hand-write `ffmpeg -i …` commands.
- **Single file only.** Pass one image with `--image`; directories are not supported.
- **Never overwrite source files.** Output goes to `image-to-png/` (or `--output`) by default.
- **Do not resize or recompress** unless the user explicitly asks — omit quality/size overrides.
- `populated: false` for `ffmpeg` is not a reason to skip. Install first, set `populated: true`, retry the same command.
## Setup (first run)
1. Download FFmpeg and extract to `.dependency/ffmpeg/` (see skill-dependency-manager).
Windows result example: `.dependency/ffmpeg/bin/ffmpeg.exe`
2. Register in `.dependency/manifest.json`:
```json
"ffmpeg": {
"populated": true,
"bin": ".dependency/ffmpeg/bin/ffmpeg.exe"
}
```
Use `bin/ffmpeg` on Unix (no `.exe`).

How to install
mdr add godot-fun/godot-agent/image-to-png@git:20260918.a3d4acfmdr add godot-fun/godot-agent/image-to-png@sha256:a725ffd885185a8aPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
