# upload_file: Upload a file

Bring a file into FynePDF. Shows a drop zone where the app supports it (Claude, ChatGPT, VS Code); it takes several files at once, e.g. for a merge, and reports their file_ids in order. With file_name and size_bytes it also returns a signed upload_url and a ready curl command, for a code sandbox or agent to PUT the bytes; the file_id works once the upload is done. ChatGPT users can just pass the attached file to any tool instead.

A tool of the [FynePDF MCP server](https://fynepdf.com/developers/docs/mcp) (`https://api.fynepdf.com/mcp`). Makes a new file; the original is kept.
