Convert Base64 to PNG

This plugin for Obsidian converts base64-encoded images in your notes to local PNG files. Reduce the size of your markdown files and make them more portable!

Demo

Features

• Base64 Detection: Automatically detects base64-encoded images in your notes
• Local Conversion: Converts base64 images to local PNG files
• Batch Processing: Process individual files or all files in your vault
• Customizable Storage: Configure where and how PNG files are stored
• Automatic Conversion: Option to automatically convert base64 images when pasting

How It Works

When you run the plugin:

1. It scans your notes for base64-encoded images
2. Decodes the base64 data to binary
3. Saves the binary data as PNG files in your configured folder
4. Updates the links in your notes to point to the local PNG files

This makes your notes smaller, more portable, and easier to work with.
