Does converting AVIF to ICO keep transparency?

Yes. Both AVIF and ICO store a full alpha channel, and FileMorf preserves it exactly — anti-aliased edges, soft shadows, and semi-transparent pixels all survive the conversion.

Does converting AVIF to ICO improve image quality?

No — detail the original AVIF compression discarded is gone for good, and no format change can restore it. What ICO guarantees is that nothing further is lost: the decoded image is stored exactly, so it will survive repeated edits and saves untouched.

Why won't my AVIF file open in some apps?

AVIF is young: browsers added support between 2020 and 2023 (Chrome 85, Firefox 93, Safari 16), but many desktop editors, viewers, and upload forms still cannot read it — which is exactly the problem converting to ICO solves.

What about animated AVIF files?

An animated AVIF is decoded as its first frame, so the output is a single still image. Static AVIF files — the vast majority — convert in full.

What sizes are included in the ICO file?

FileMorf embeds the standard icon sizes — 16, 32, 48, 64, 128, and 256 pixels — up to your source image's own size, each stored as a PNG inside the .ico container. Browsers and Windows then pick the crispest match for wherever the icon appears: browser tabs, bookmarks, taskbars, or desktop shortcuts. Start from a source of 256px or larger to get the full set.

Questions about AVIF and ICO.

Check the format behavior, limitations, and follow-up options before processing a real file.

If a logo or mark was delivered as AVIF, no icon editor or favicon pipeline will take it directly — .ico remains the format browsers request by default and Windows uses for shortcuts and executables. FileMorf decodes the AVIF, renders the standard icon sizes, and packs them into one PNG-compressed .ico with alpha transparency preserved. Start from a square-ish source of 256px or larger for the sharpest result.
