# pdfia

> Free, private PDF tools. Every browser tool runs 100% client-side (files never leave the user's device). For AI agents, pdfia also offers a free REST API and an MCP server that process files in-memory and never store them.

## For AI agents (programmatic access)

- MCP server (Streamable HTTP, no auth): https://pdfia.com/mcp
  Add to an MCP client as: {"type": "http", "url": "https://pdfia.com/mcp"}
  Tools: merge_pdfs, split_pdf, extract_pages, remove_pages, rotate_pdf, watermark_pdf, add_page_numbers, get_pdf_metadata, set_pdf_metadata, flatten_pdf. PDFs are passed as base64 strings.
- REST API index (JSON, self-describing): https://pdfia.com/api
  POST https://pdfia.com/api/v1/{merge|split|extract|remove|rotate|watermark|page-numbers|metadata|flatten} with a JSON body; files as base64.
- Docs for both: https://pdfia.com/developers/
- Limits (free): 10 MB per file, 20 files per request, ~30 operations per 10 minutes per IP.
- Privacy: API/MCP files are processed in-memory only — never stored, never logged.
