About the WebP to ICNS Converter
Convert WebP to ICNS online for free, with no account and no watermark. Many older apps, photo editors and upload forms still reject WebP files, so switching to ICNS is the quickest way to get a Retina-ready macOS icon for macOS app icons, Electron and Xcode projects and custom folder icons.
The converter decodes your WebP with your browser's own image engine and writes the ICNS with a small open-source ICNS encoder, so quality settings are applied precisely. Because everything happens on your own device, your images are never uploaded, stored or seen by anyone else, which makes it safe for ID photos, Aadhaar or PAN scans and personal pictures.
What to expect: transparency is preserved because both WebP and ICNS support an alpha channel; only the first frame of an animated WebP is converted; ICNS stores the pixels without further quality loss; camera metadata such as GPS location is removed because the image is re-encoded.
How to use the WebP to ICNS Converter
- Click "Choose files" or drag your WebP images onto the box. You can add several at once.
- Optionally set a background colour; all standard icon sizes are generated automatically.
- Press "Convert to ICNS". The conversion runs on your device and shows its progress.
- Download each ICNS file, or use "Download all (ZIP)" when you converted several.
- Open the result in macOS Finder or Xcode to check it; your original WebP is never changed.
Tips & benchmarks
- Use a square source of 1024×1024 px for the sharpest Retina icon; 128, 256, 512 and 1024 px sizes are included.
- Animated WebP files are converted from their first frame; use our video tools if you need every frame.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the ICNS to a website or government portal.
