# Convert to WebP Convert one or more images to WebP format. ## Usage Arguments: one or more file paths, optionally followed by `--dest <directory>` and/or `--quality <number>`. Examples: - `/convert-to-webp /tmp/screenshot.png` - `/convert-to-webp /tmp/a.png /tmp/b.jpg --dest /path/to/site/static/images` - `/convert-to-webp /tmp/photo.jpg --quality 90` ## Instructions First, check which tool is available (run once per session): 1. **`cwebp`** -- best quality control. Install via `brew install webp` 2. **`sips`** -- built into macOS (Monterey+), no install needed. No quality flag for WebP output. Pick whichever is available. Prefer `cwebp` if both exist. For each input file: 1. Skip if the file is already `.webp` 2. Determine the output path: - If `--dest` is provided, output to that directory with the same filename but `.webp` extension - Otherwise, output to the same directory as the input with `.webp` extension 3. Convert: - **cwebp**: `cwebp -q <quality> <input> -o <output>` (default quality: 85) - **sips**: `sips -s format webp <input> --out <output>` 4. Report the output path and file size ## Provenance This skill drives two interchangeable command-line tools and bundles neither: - **[`cwebp`](https://developers.google.com/speed/webp/docs/cwebp)** — part of Google's **libwebp** (© Google, [BSD-3-Clause](https://chromium.googlesource.com/webm/libwebp/+/refs/heads/main/COPYING)), installed separately via `brew install webp`. - **`sips`** — Apple's
