About PressIt

PressIt is an MCP server for compressing, resizing, and converting images locally. It supports JPG, PNG, WebP, and GIF, keeps originals unchanged, and does not upload files or require an API key.

Key features

  1. 01Compress a single image
  2. 02Process folders or file lists
  3. 03Resize and convert images
  4. 04Keep original files unchanged
  5. 05Handle JPG, PNG, WebP and GIF

Use cases

  1. 01Reduce image file sizes before sharing
  2. 02Batch-process images in a folder
  3. 03Convert images to another supported format

MCP support

The server exposes `compress_image` for one file and `compress_images` for a folder or list of files.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
  "mcpServers": {
    "alireza99-pressit": {
      "command": "npx",
      "args": [
        "-y",
        "pressit-mcp"
      ]
    }
  }
}
Run commandnpx -y pressit-mcp

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.
