About the JPG to ICNS Converter
Convert JPG to ICNS online for free, with no account and no watermark. JPG has no transparency and loses a little quality every time it is saved, 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 JPG 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 photos 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: 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 JPG to ICNS Converter
- Click "Choose files" or drag your JPG photos 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 JPG 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.

JPG (JPEG) is the most widely used photo format in the world, standardised in 1992. It shrinks photographs dramatically by discarding detail the eye barely notices, but it has no transparency and loses a little quality every time it is re-saved.

ICNS is the icon format macOS uses for apps, folders and disk images. A single ICNS file bundles the same icon at several resolutions, up to 1024×1024 pixels for Retina screens.
