Your Own Webp Converter

By Narasimha
What it Does:
- Turns your JPG and PNG images into WebP images (good for websites).
- Makes image file sizes smaller so websites load faster.
- Keeps your subfolder organization.
- With simple GUI
What You Need:
- Python installed on your computer.
- To install one extra thing called "Pillow".
How to Install Pillow (One Time Only):
- Open your computer's Terminal or Command Prompt.
- Type **pip install Pillow ****and press Enter.
How to Use:
- Save the below Script: Save the code as webp_converter.py.
- Prepare Images: Put your JPG/PNG images into an Input Folder. You can make subfolders inside (like featured, gallery) - the script will copy that structure. Likewise, create an Output Folder where webp images get stored.
- Run Script: Open Terminal/Command Prompt, go to where you saved the script (cd path/to/script), and type python webp_converter.py or alternatively you can use VSCode for the same.
- Use the Pop-up Window:
- Click "Browse..." next to "Input Folder" and choose the folder with your images.
- Click "Browse..." next to "Output Location" and choose where you want the results saved.
- Leave "Strip Metadata" checked (usually best).
- Click "Start Conversion".
- Wait: Watch the status bar at the bottom. It will say "Finished" when done.
What You Get (in your chosen Output Location):
- WebP_Output folder: Contains your new .webp images, organized like your input folder. Use these for your website!
- Error_Files folder: If the script couldn't read an original image, it moves the bad original file here.
- error.log file: A text file with details about the last run (errors, how much smaller files got). It gets replaced each time you run the script.
Good to Know:
- It aims for high quality (Quality 85) but uses "lossy" compression to save space (like JPGs do).
- It works hard to make files small (Method 6), so it might take a little time for many images.
- If your PNGs had clear backgrounds, they will have white backgrounds in the WebP version.
