What it does

Image To Png is an agent skill from godot-fun/gai. 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.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `reference.md`).

It sits in Media & Creative, covering Video production and Image editing. It works with FFmpeg. The repository describes itself as: A lightweight AI agent and skill workflow framework built with Godot. The licence is MIT.

When your agent uses it

The user wants to convert images to PNG
Transcode JPG/WebP/GIF/BMP/TIFF to PNG

Example prompts

“Use the image-to-png skill to convert image files to PNG using FFmpeg while preserving dimensions and alpha”
“/image-to-png”

Requirements

Python 3

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

Download FFmpeg and extract to .dependency/ffmpeg/ (see skill-dependency-manager).
Register in .dependency/manifest.json

What it can do on your machine

Read from SKILL.md and the folder at commit 6394686. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- python
- ffmpeg
- git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Image To Png loads about 1.1k tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 428 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~68
When it runs · the whole SKILL.md, loaded when a task matches: ~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: image-to-png
description: 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.

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 — 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)

Download FFmpeg and extract to .dependency/ffmpeg/ (see skill-dependency-manager).

Windows result example: .dependency/ffmpeg/bin/ffmpeg.exe
Register in .dependency/manifest.json:

json

"ffmpeg": {
  "populated": true,
  "bin": ".dependency/ffmpeg/bin/ffmpeg.exe"
}

Use bin/ffmpeg on Unix (no .exe).

Quick Start

Default: create an image-to-png/ folder beside the input file and write the PNG there:

bash

# assets/ui/icon.webp → assets/ui/image-to-png/icon.png
.dependency/python/python .ai/image-to-png/convert.py --image assets/ui/icon.webp

Custom output path:

bash

.dependency/python/python .ai/image-to-png/convert.py --image assets/ui/icon.webp -o assets/ui_png

Strip alpha (RGB output):

bash

.dependency/python/python .ai/image-to-png/convert.py --image assets/sprites/hero.webp --strip-alpha

Format Defaults

Setting	Default	Notes
Dimensions	Preserve source	No resize unless user asks separately
Alpha	Preserve	RGBA when source has transparency
Already PNG	Stream copy	Bit-perfect when `--strip-alpha` is off
Animated GIF	First frame	Multi-frame GIF export not supported

Defaults

Option	Default	Notes
`--image`	Required	Single supported image file
Output	`<image-dir>/image-to-png/<name>.png`	Use `-o` / `--output` for custom file or directory
`--strip-alpha`	off	Force RGB PNG without alpha

Supported inputs: .jpg, .jpeg, .png, .webp, .gif, .bmp, .tif, .tiff, .avif, .ico.

Agent Workflow

Paths — Pass whatever image path the user gives. Output lands in image-to-png/ next to that file by default.
One file per run — convert one image, verify the result, then repeat for additional files if needed.
Already PNG? Stream-copied by default (no generation loss) unless --strip-alpha is set.
Revert — delete output file or git restore; sources are never modified.

Agent Notes

Use the bundled script, not hand-written FFmpeg commands.
Missing Python/FFmpeg → populate .dependency/ per skill-dependency-manager, retry same command.
Do not copy, move, or replace the source with converted output — tell the user where the output file is.
Need transparent cutouts → use image-remove-background, not this skill.
Need resize after conversion → image-resize.
FFmpeg codec and probing details: reference.md

Troubleshooting

Issue	Fix
`ffmpeg` missing in manifest	Follow Setup; update manifest
Directory passed to `--image`	Run once per file; this skill accepts image files only
Output already exists	Delete the existing output or choose a different `-o` path
Animated GIF	Only first frame is exported by default
Need RGB only	Add `--strip-alpha`

CLI

Copy-paste commands: cli/image-to-png.md

Resize after conversion: image-resize
Transparent cutouts: image-remove-background
