There are a lot of online converters for converting images to WEBP format, but all of them are paid after the first 5-10 free conversions. These online converters can also lead to data privacy and image copyright issues. Even with all the disclaimers, there might be a question of who owns the content that these platforms create for you.

So I created this WEBP Converter for Mac for my personal use.

Using WebP images in websites offers benefits such as reduced file sizes for faster loading times, improved SEO rankings, and bandwidth savings. WebP supports transparency and is compatible with modern browsers, making it an efficient choice for responsive design and high-resolution displays. Its open and actively maintained nature also ensures future compatibility and performance enhancements.

Technologies Used:

  • Python: The core programming language used to create the application.
  • Pillow (PIL Fork): A powerful Python Imaging Library that supports opening, manipulating, and saving many different image file formats.
  • Tkinter: A standard GUI (Graphical User Interface) package in Python used to create the application’s interface.


  • Folder Selection: Users can select a specific folder, and the application will recursively convert all supported image files within that folder and its subdirectories to the WEBP format.
  • Support for Multiple Image Formats: The application supports a variety of image formats including PNG, JPG, JPEG, BMP, GIF, and TIFF.
  • User-Friendly Interface: The application features a simple and intuitive interface, allowing users to easily select the folder for conversion.
  • Last Folder Memory: The application remembers the last folder that was opened, making it convenient for users who are working with images in the same directory.
  • Conversion Notification: After the conversion process is complete, the application provides a notification to inform the user that the images have been successfully converted.

How It Works:

  1. Initialize the Application: The application starts with a Tkinter window where users can interact with the GUI.
  2. Select Folder: Users click a button to open a dialog box for folder selection. The application remembers the last selected folder for future convenience.
  3. Convert Images: Upon folder selection, the application recursively goes through the folder, finds all supported image files, and converts them to the WEBP format.
  4. Provide Feedback: After the conversion is complete, a message box pops up to inform the user that the images have been converted, and the application window closes gracefully.
  5. Exit: The application closes, and the user is left with their images converted to the WEBP format in the same directory as the original images.

The WEBP Image Converter is a handy tool for anyone looking to optimize their images for the web. Its support for multiple image formats, combined with a user-friendly interface, makes it a practical choice for both individuals and professionals alike.
