What it does
Format Converter is an agent skill from AFK-surf/OpenBridge. Convert files between formats. Use for Document conversion, Image format conversion, and Audio/Video format conversion.
Its SKILL.md is about 550 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/av-convert.md`, `references/document-convert.md` and `references/image-convert.md`).
It sits in Documents & Office, covering Document parsing. The repository describes itself as: A free, safe and open agent for everything. Alternative to Claude Cowork & Codex. Open Bridge, the AI bridge between your intention and get the job done. The licence is MIT.
When your agent uses it
- Document conversion
- Image format conversion
- Audio/Video format conversion
Example prompts
- “/format-converter”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit a9ca905. 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:
pandocapt
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Format Converter loads about 549 tokens when it runs, and up to ~2.3k if it reads all its reference files. Until then it costs about 34 tokens; SKILL.md has 153 words of instructions outside code blocks.
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.

File Format Conversion
Execution Environment
Run format conversion commands in the local VM environment by default. Do not perform conversion work on local macOS or a cloud VM unless the user explicitly asks for that environment.
Workflow Decision
| Task | Tool | Reference |
|---|---|---|
| Document conversion | pandoc | document-convert.md |
| Image format conversion | Python (Pillow) | image-convert.md |
| Audio/video conversion | ffmpeg | av-convert.md |
Quick Reference
Document Conversion
Read references/document-convert.md for detailed workflow.
Key points:
- PDF generation: ALWAYS use
--pdf-engine=weasyprint(lightweight, auto-installed) - Pandoc supports markdown, HTML, PDF, DOCX, LaTeX, and many more formats
# PDF from markdown
pandoc input.md -o output.pdf --pdf-engine=weasyprint
# DOCX from HTML
pandoc input.html -o output.docxImage Conversion
Read references/image-convert.md for detailed workflow.
Key points:
- Use
Image.LANCZOSfor any resize operation (prevents color banding/aliasing) - Convert RGBA to RGB before saving as JPEG
- Preserve EXIF metadata when possible
# Dependencies
apt install python3-pil python3-pillow-heifAudio/Video Conversion
Read references/av-convert.md for detailed workflow.
Key points:
- Use
-c copywhen only changing container format (fast, lossless) - Use
flags=lanczosin scale filters for best quality - Use
-crffor quality-based encoding
Check ffmpeg available before using it.
