convert-img - Command

Description​

Converts a Base64 encoded image string (often found in Minecraft server favicons as a Data URI) into a physical image file. This utility is useful for extracting and saving server icons.

Usage​

./ServerRawler convert-img <FILE_PATH> <BASE64_STRING>
  • <FILE_PATH>: The path where the image file should be saved (e.g., favicon.png). The file extension will determine the output format.
  • <BASE64_STRING>: The full Base64 encoded string.

Examples​

tip

In some cases, its better to put the Base64 string in a variable to avoid issues with special characters in the terminal.
For example, in bash you can do:

BASE64_STRING="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAA..."
./ServerRawler convert-img favicon.png "$BASE64_STRING"

To convert a Base64 string to a PNG image:

./ServerRawler convert-img favicon.png "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAA..."

To convert a Base64 string without the Data URI prefix:

./ServerRawler convert-img image.jpg "iVBORw0KGgoAAAANSUhEUgAA..."
