Choose icon-ready AVIF artwork
Add an AVIF with a clear subject and enough empty margin for a square icon. The browser decodes it locally.
Free AVIF to ICNS converter
Convert AVIF to ICNSfor a macOS icon handoff.
Fileverses turns a browser-decoded AVIF image into an ICNS icon file on your device. It creates centered PNG icon entries from 16 through 512 pixels, so start with simple, high-contrast artwork and inspect the small sizes before adding the file to a macOS project.

About this converter
Free AVIF to ICNS conversion, built for a real workflow.
AVIF is a compact modern raster format, while ICNS is Apple’s icon container for macOS. This route decodes the AVIF in your browser and packages transparent, square PNG entries at 16, 32, 64, 128, 256, and 512 pixels inside one ICNS file. A rectangular source is scaled to fit each square and padded rather than cropped. That makes it useful for an explicit icon-file requirement, but it does not design an icon, create a macOS application bundle, add a 1024-pixel entry, or recover detail that becomes unreadable at small sizes.
- This ICNS export contains centered PNG entries at 16, 32, 64, 128, 256, and 512 pixels; it does not create a macOS app bundle or a 1024-pixel icon entry.
- A non-square AVIF is scaled to fit within each square icon and receives transparent padding rather than being cropped. Check the resulting silhouette at 16 and 32 pixels.
- ICNS can retain transparent pixels because its icon entries are PNG images, but conversion cannot remove an existing background or invent clean icon edges.
- Use a simple source with clear contrast for toolbar, dock, or app-icon work. Fine photographic detail can disappear after downscaling.
How it works
Upload once.
Export ICNS.
Keep ICNS selected
ICNS is preselected here for a macOS icon-file workflow. The converter fits the source into six square PNG icon sizes.
Download and inspect
Open the ICNS in the target macOS project or icon viewer, especially checking the 16- and 32-pixel entries before shipping it.

Good to know
Questions, answered.
When should I convert AVIF to ICNS?+−
Use this route when a macOS project or icon workflow explicitly needs an ICNS file. AVIF is better kept for modern image delivery; ICNS is an icon container rather than a general-purpose web image.
Which icon sizes does this AVIF to ICNS converter create?+−
Fileverses packages PNG entries at 16, 32, 64, 128, 256, and 512 pixels. It does not add a 1024-pixel entry or create an app bundle.
Will a rectangular AVIF be cropped into a square ICNS icon?+−
No. The encoder scales the decoded image to fit inside each square and leaves transparent padding around it. Review the small icon entries because a wide or tall source can look small at 16 pixels.
Does AVIF transparency stay in the ICNS file?+−
The ICNS entries are encoded as PNG images, so transparent pixels can be preserved. The converter does not create transparency from an opaque source or remove a background.
Can AVIF to ICNS make a polished macOS icon from any image?+−
No. It packages rendered pixels at fixed icon sizes. It cannot redesign artwork, restore lost detail, or ensure that a detailed photograph remains recognizable at small sizes.
Does Fileverses upload AVIF files to create ICNS icons?+−
No. Fileverses performs this AVIF-to-ICNS conversion in your browser, so the source image is not sent to a conversion server.
