Automatically finds and converts JPG, PNG, GIF, BMP, TIFF, and existing WebP files\n","- **Smart Conversion**: Handles transparency by converting RGBA/P modes to RGB with white background\n","- **High-Quality WebP**: Uses 85% quality setting for optimal size/quality balance\n","- **Recursive Search**: Processes images in subfolders too\n","- **Error-Resilient**: Skips corrupt files and

How It Works\n","1. Mounts your Google Drive\n","2. Scans for image files in \"Saved from Chrome/\" and subdirectories\n","3. Converts each image to WebP with sequential numbering\n","4.
