ss-format-convertlisted

Convert images between formats: PNG, JPG/JPEG, WebP, TIFF, BMP, GIF, HEIC, and AVIF. Performs high-quality lossless conversion by default. Handles alpha channel transparency automatically — compositing against a configurable background color when converting to formats that lack alpha support (JPG, BMP). Supports single-file and batch directory conversion with optional recursive subdirectory scanning. Uses ImageMagick. Use this skill whenever the user wants to: convert an image to another format, change image format, save as PNG/JPG/WebP/TIFF, convert HEIC photos to JPG or PNG, batch convert images, make images web-compatible, convert to WebP for web optimization, or anything involving image format conversion. Also trigger when the user mentions format names in the context of converting, exporting, or saving images.
