Why choose ICNS over other formats?

macOS Icon offers supports retina-resolution icons up to 1024x1024. It's widely used for macOS application icons and Finder icons, making it an excellent choice for most image needs.

Will my JPEG file be deleted after conversion?

No. Your original JPEG file is never modified or deleted. Xonvert creates a separate ICNS copy — your source file remains untouched.

What image quality settings should I use?

For photos, use the High quality preset. For web graphics, Medium offers a good size-quality balance. The default preset works well for most use cases.

Does this work on my phone or tablet?

Yes. Xonvert works on any device with a modern browser — iPhone, iPad, Android phones and tablets all supported.

Can I undo a conversion?

Since your original JPEG file is never modified, there's nothing to undo. Your source file remains exactly as it was — only a new ICNS copy is created.
