Extract Text from PDFs
Pull raw text from any PDF URL so you can search, quote, or process its contents programmatically.
Merge Multiple PDFs
Combine several PDF files from public URLs into a single merged document.
Quick answer: Use the PDF tool through ToolRouter to merge multiple pdfs directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolSending five separate PDFs when a client needs one package, or assembling a final deliverable from a dozen sourced documents, is a workflow that breaks down fast without the right tool. Online PDF mergers require uploading files one by one, often have size limits, and raise privacy concerns with sensitive documents.
The merge skill takes a list of PDF URLs and combines them into a single file in the order you specify. No upload required — point it at public URLs and receive the merged document back. Page order follows the URL sequence you provide.
Operations teams compiling compliance packs, marketing teams assembling proposal packages, and researchers bundling supporting documents all use this to produce a single clean file without juggling tools.

Claude handles PDF merging with order confirmation — tell it which documents to combine and in what sequence, and it confirms the final structure before merging. Useful when you want to verify the page order makes sense before generating the output file.
How to merge multiple pdfs
Once connected (see setup above), use the PDF tool — the same steps work with Claude, ChatGPT, Microsoft Copilot, OpenClaw, and any MCP client:
- Provide your PDF URLs: "Merge these PDFs in this order: [url1], [url2], [url3]"
- Claude confirms the merge sequence and proceeds
- Receive the merged PDF as a downloadable link
- Ask Claude to verify the page count matches your expectation
Example prompt
Try this with the PDF tool
Merge these three PDFs into one document in this order: cover page at https://example.com/cover.pdf, main report at https://example.com/report.pdf, appendix at https://example.com/appendix.pdf.
Tips
- List URLs in the exact order you want pages to appear in the final document
- Ask Claude to confirm how many pages each source document contributes
- Use public file storage links (S3, Google Drive public share) for your source files
