Konvizi for AI assistants

Ask your assistant to “merge these PDFs” and it does it itself, on your computer.

What is it?

konvizi-mcp is the version of Konvizi made for AI assistants. It uses MCP (Model Context Protocol), the open standard that lets an assistant such as Claude use tools. Once it is installed, your assistant no longer just explains how to convert a file: it does the conversion itself.

Just like the website, everything stays with you: the program runs on your computer, reads your files and writes the result next to the original. Nothing is uploaded, and an existing file is never overwritten.

What your assistant can do

Images
Convert between JPG, PNG, WebP, AVIF, GIF, TIFF and ICO, read iPhone HEIC photos and SVG, compress and resize.
Images and PDF
Put images into one PDF, or turn each page of a PDF into an image.
PDF pages
Merge, split, extract, delete, reorder or rotate pages.
Text
Extract the text of a PDF or a Word document (.docx), create a PDF or a Word file from text.

Installation

You need Node.js (version 20 or later), free from nodejs.org. Then:

Claude Desktop

Open Settings › Developer › Edit Config, add this block to the file, then restart Claude.

{
  "mcpServers": {
    "konvizi": {
      "command": "npx",
      "args": [
        "-y",
        "konvizi-mcp"
      ]
    }
  }
}

Claude Code

In a terminal:

claude mcp add konvizi -- npx -y konvizi-mcp

Cursor, Windsurf, VS Code

Add the same block as for Claude Desktop to the MCP configuration (in VS Code the key is “servers” instead of “mcpServers”).

Things you can ask

Limits

Tools that need more settings stay on konvizi.com: OCR, audio, Excel/CSV/JSON, compressing, protecting, unlocking, signing or numbering a PDF, watermarks. Assistants that only run in a web browser (ChatGPT or Claude on the web) cannot start a program on your computer: for them, the website is the simplest option.

Frequently asked questions

Are my files sent to Konvizi or to the assistant?

Not to Konvizi: konvizi-mcp does the conversion on your computer and connects to no server. The assistant only receives the report (the names of the files created and, when extracting text, the text itself so it can summarise it for you).

Is it free?

Yes. konvizi-mcp is free and open source (MIT licence), published on npm as konvizi-mcp.

Which assistants are supported?

Any assistant that accepts local MCP servers: Claude Desktop, Claude Code, Cursor, Windsurf, VS Code (GitHub Copilot) and many more.
