n8n-nodes-tag-media

This is an n8n community node. It lets you read and write metadata tags to media files in your n8n workflows.

These nodes enable embedding metadata into audio files, images, PDFs, and Office documents - useful for digital asset management, media libraries, automated file organization, and content workflows.

n8n is a fair-code licensed workflow automation platform.

Output options:

• Include all fields
• Include only specific fields
• Exclude specific fields

Compatibility

• Minimum n8n version: 1.111.0
• Tested with: n8n 1.111.0

Platform Notes

• Docker: Recommended for easiest setup of Python and exiftool dependencies
• Windows: Requires Python and exiftool installed and available in PATH
• Linux/macOS: Install dependencies via package manager

Usage

Basic Workflow

1. Use a trigger or file input node to get your file
2. Connect to a Tag node to write metadata
3. The node outputs the modified file as binary data
4. Save or process the file further in your workflow

Example: Tag Audio Files from Database

[Database Trigger] → [HTTP Request (download file)] → [Tag Audio File] → [S3 Upload]

Example: Add Copyright to Images

[Watch Folder] → [Tag Media File (add copyright)] → [Move File]

Extended Properties

All tag nodes support extended properties for format-specific metadata:

1. Enable "Extended Properties" in the node settings
2. Click "Add Property"
3. Select a field from the dropdown or choose "Custom" to enter any tag name
4. Enter the value (supports expressions)
