About

Image to PNG

Convert supported image formats 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](../../rules/skill-dependency-manager.md) — run scripts as documented, install missing tools into .dependency/.

Quick Start

Convert a file or folder, output to png/:

.dependency/python/python .cursor/skills/image-to-png/scripts/convert.py path/to/image_or_folder

Example: assets/ui/icon.webp → assets/ui/png/icon.png

Batch with subfolders:

.dependency/python/python .cursor/skills/image-to-png/scripts/convert.py assets/textures -r

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 no overrides | | Animated GIF | First frame | Multi-frame GIF export not supported |

Common Flags

-r · -o / --output-dir · --strip-alpha · --dry-run · --overwrite

Strip alpha (RGB output):

.dependency/python/python .cursor/skills/image-to-png/scripts/convert.py assets/sprites -r --strip-alpha

Custom output directory:

.dependency/python/python .cursor/skills/image-to-png/scripts/convert.py assets/ui -o assets/ui_png --dry-run

Never overwrite source files. The script writes only to png/ (or -o). Supported inputs: .jpg, .jpeg, .png, .webp, .gif, .bmp, .tif, .tiff, .avif, .ico.

Agent Notes

Use the bundled script, not hand-written ffmpeg -i … commands.
Do not resize or recompress unless the user explicitly asks — omit quality/size overrides.
Already PNG? Stream-copied by default (no generation loss).
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 png/ files are; they swap assets manually when ready.
Need transparent cutouts → use [image-remove-background](../image-remove-background/SKILL.md), not this skill.
