Convert images to webp and base64

Small python script to resize and convert images to webp and provide base64 data in a .txt file


The Base64 Convert App is a Python script that automates the process of converting images to Base64 format and resizing them. It’s particularly useful for embedding images directly into Markdown files for Jekyll-based websites. The app also generates WebP versions of the images for better compression and quality.


  • Converts images in the images folder to Base64 format.
  • Saves the Base64 string to a .txt file with the same name as the image.
  • Resizes the image to 250x160 pixels.
  • Converts the resized image to WebP format.
  • Saves the WebP image with a _converted.webp suffix.

How to Use

  1. Setup: Place the convert.py script in the same directory as your images folder.
  2. Batch File: Double-click the provided .bat file. This will set up a Python virtual environment, install required packages, and run the convert.py script.
  3. Output: After running, you’ll find a .txt file containing the Base64 string and a _converted.webp image in the images folder for each image processed.


  • Python 3.x
  • Pillow library (automatically installed by the .bat file)


  • The .bat file will check if a virtual environment already exists. If it does, it will simply activate it and run the script.
  • Detailed logs will be displayed in the CMD window, including any errors.


Use the convert.sh

give it execute permissions (chmod +x convert.sh), and then you can run it with ./convert.sh
