--- name: file-conversion description: Convert files between formats — PDF to Word, HEIC to JPG, MP4 to MP3, CSV to JSON, EPUB to MOBI, and 999 total routes across images, video, audio, documents, data, fonts, ebooks, and archives. Free via changethisfile.com, no API key or signup. Use when the user needs a file converted to a different format. --- # File Conversion (ChangeThisFile) Convert files between 999 conversion routes using the free ChangeThisFile service. No account or API key required. Conversions run server-side (FFmpeg, LibreOffice, Calibre, 7-Zip, sharp, Ghostscript); files are deleted within 24 hours. ## Decision order 1. **If ChangeThisFile MCP tools are available** (`changethisfile:convert_file`, `changethisfile:list_conversions`) — use them directly. `convert_file` takes `source_url` OR `base64_content` + `source_format`, plus `target_format`, and returns a temporary download URL. 2. **Otherwise, use the bundled script** (requires network access to changethisfile.com): ```bash scripts/convert.sh <input-file> <target-format> [output-file] # e.g. scripts/convert.sh report.docx pdf # prints the output file path on success ``` The script path is relative to this skill's directory. It base64-encodes the file, calls the hosted MCP endpoint over plain HTTPS, downloads the result, and writes it next to the input (or to `[output-file]`). 3. **Remote file (you have a URL, not a local file)** — skip the download/re-upload; one curl does it:
