Merge PDF

Merge PDFs in the order you choose

Combine several readable PDFs into one artifact, preserve input order, and verify the resulting page facts.

Choose two or more PDFs, arrange the input order in the workspace and check the combined output. No login is needed within guest limits; automation uses free account file references.

Local checks stay in your browser. Basic image and PDF processing works without login and uploads files only when you run it.

Server conversions use this mode to decide whether output is accepted.

Default: 200,000 bytes (about 200KB)

How it works
  1. Choose source PDFs in the public workspace, or use a free account with REST or MCP.
  2. Arrange files in the exact order required for the submission.
  3. Apply page or size rules and download the checked merged artifact.
Current limits
  • Every source must be a readable application/pdf file.
  • The combined document is limited to 100 pages.
  • Owner scope, short-lived artifacts, and idempotency protect repeat calls.
Questions

Can an AI agent call the merge tool?

Yes. The same merge_pdfs contract is exposed through the authenticated REST API and Streamable HTTP MCP server.
