How to Compress PDFs with Copilot
Compress PDFs in your IDE with Copilot and ToolRouter. Add PDF optimisation to your document processing pipeline.

Steps
Once connected (see setup above), use the Compress tool:

- Copilot returns the compressed file URL and size
- Ask: "Write TypeScript code that compresses a PDF if it exceeds 5MB"
- Add the compression gate to your document workflow
Example Prompt
Try this with Copilot using the Compress tool
Compress this PDF and write TypeScript code that calls the compress skill and logs the before/after file sizes: https://example.com/report.pdf
Tips
- Use compression as a middleware step before storing user-uploaded PDFs
- Ask Copilot to write a conditional that only compresses if the input exceeds a size threshold
- Integrate with the PDF merge skill to compress the output of every merge automatically
