Free JPG to ICNS converter

Why convert JPG to ICNS?

People convert JPG to ICNS because JPG discards a little more detail every time it is saved, and it cannot store a transparent background, while ICNS is what macOS needs before it will show an application icon at all.

How to convert JPG to ICNS

1. Choose your JPG file. Drop it on the box above, or tap to browse. You can pick several files at once.
2. Confirm the target is .icns. It is preselected when your browser can encode it; otherwise the closest available target is chosen. Adjust quality, size or the other options if you want to.
3. Convert and download. Press Convert, then Download. Your file stays on your device the whole time.

What is a .jpg file?

JPG (also written JPEG) is the universal photograph format — small files that open on every device made in the last twenty-five years. It is lossy, discarding detail the eye is least likely to miss, which makes it excellent for photos and poor for screenshots, logos and text, where it leaves visible smudging.

What is a .icns file?

ICNS is macOS's icon container, the Apple counterpart to Windows ICO. It bundles several resolutions of the same artwork, up to 1024 pixels, so an icon stays crisp from the Dock to a Finder preview.

What to expect from this conversion

The target format is lossless, so every pixel of the decoded image is preserved exactly. The result can be larger than the original, which is the normal trade for keeping full quality. macOS icons are square, so a picture that is not square is fitted inside one.

Is it private?

Yes, by design. Every conversion happens inside your own browser using your device’s processor — there is no server that receives your JPG file, so there is nothing for anyone to store, scan or leak. You can confirm it yourself: open your browser’s developer tools, watch the Network tab while you convert, and you will see no upload.
