Free TIFF to ICNS converter

Why convert TIFF to ICNS?

People convert TIFF to ICNS because TIFF is what scanners and print shops produce, and browsers and messaging apps will not display it, while ICNS is what macOS needs before it will show an application icon at all.

How to convert TIFF to ICNS

1. Choose your TIFF 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 .tiff file?

TIFF is the lossless format of scanners, print workflows and archives, able to hold multiple pages and very high bit depths. Files are large, and browsers cannot display one, so a TIFF usually has to be converted before it can be shared or put on a web page.

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. Multi-page TIFFs are common from scanners — each page comes out as its own file. 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 TIFF 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.
