About this converter

Free WEBP to ICNS conversion, built for a real workflow.

WEBP is a web image format that a browser can decode into pixels. ICNS is an icon container used for macOS icon families. This free online WEBP to ICNS converter starts with that rendered image and packages six centered PNG entries at 16, 32, 64, 128, 256, and 512 pixels. It is a practical way to prepare an icon-family file from a single image, but it does not create an app bundle, select from a source container, or preserve WebP bytes and metadata.

WEBP must decode in the browser before the ICNS package can be made.
The output contains six PNG-backed icon entries: 16, 32, 64, 128, 256, and 512 pixels.
Each entry uses contain scaling with transparent padding; the converter does not crop the artwork.
Decoded transparency can remain in the PNG icon entries, but the conversion cannot create missing transparency.
ICNS output is an icon container only: it does not create a macOS app bundle or guarantee a particular app workflow.

Good to know

Questions, answered.

Is this WEBP to ICNS converter free?+−

Yes. Fileverses offers this WEBP to ICNS conversion free online without an account or sign-up.

Where does WEBP to ICNS conversion happen?+−

The converter works from the image decoded in your browser. Files are not sent to a conversion server by this tool.

Which icon sizes are in the ICNS file?+−

The file contains PNG-backed entries at 16, 32, 64, 128, 256, and 512 pixels. It does not add a 1024-pixel entry.

Will the converter crop my WEBP into a square?+−

No. It scales the rendered image to fit each square entry and leaves transparent padding around it where needed.

Will WEBP transparency remain in ICNS?+−

Transparency present in the browser-decoded image can remain in the PNG entries. The tool does not remove backgrounds or create transparency.

Does an ICNS download make a macOS app icon automatically?+−

No. The download is an ICNS icon container. Adding it to an app or another macOS workflow is a separate step that should be tested in the destination application.
