About the TIFF to ICNS Converter
Need to turn a TIFF file into ICNS? This free converter changes TIFF images into ICNS in a few seconds, right in your browser. People usually convert because TIFF files are too big for email and do not display in web browsers, while ICNS gives you a Retina-ready macOS icon. ICNS files open in macOS Finder, Xcode, Electron Builder and icon editors.
The converter decodes your TIFF 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 TIFF and ICNS support an alpha channel; 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 TIFF to ICNS Converter
- Click "Choose files" or drag your TIFF 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 TIFF 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.
- Password-protected (encrypted) archives cannot be converted; extract them with the password first.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the ICNS to a website or government portal.
