Markdown Embedded Image Extractor

Markdown Image Extractor

This repository contains a Python script that extracts base64 embedded images from a markdown file, saves them to disk as binary images, and outputs a modified version of the markdown file with references to the new image files.

The script supports output with both the standard markdown image embed format (!(alt text)[filename.png]) and with Obsidian's markdown image embed format (![[image_name.png]])

Usage

This project requires Python 3.8 or above.

The script can be run from the command line with the following arguments:

• input_filename: The name of the input markdown file
• --output_dir: The destination folder for output (defaults to "output")
• --image_prefix: Prefix for image filenames (e.g. the "image_" portion of "image_0.png", "image_1.png", etc.)
• --obsidian_format: Outputs the image embed code in Obsidian format: ![[image_name.png]]

Example usage:

python main.py input.md --output_dir output --image_prefix image_ --obsidian_format

This will process the input.md file, save the extracted images to the output directory with filenames starting with image_, and output a modified version of the input.md file with image references in Obsidian format.
