What does converting AVIF to ICO mean?
AVIF is a next-generation format based on the AV1 video codec offering the best compression of any mainstream image format, while ICO is a container format for small multi-resolution icons used as favicons and desktop shortcuts. Turn your next-gen AVIF into a multi-size ICO favicon — perfect for browser tabs and app icons.
AVIF routinely produces files 50% smaller than JPG at the same visual quality, and supports transparency and a wide color range. Browser support is strong in all current major browsers, though very old software may not display it.
ICO files bundle multiple resolutions (16×16, 32×32, and 48×48) of the same image into a single file, which is why browsers and operating systems use it specifically for favicons and application icons.

When to convert AVIF to ICO
Preparing AVIF files for browser favicons and desktop application icons

Reducing file size
If ICO compresses better than AVIF for your content, converting can significantly cut storage and bandwidth needs.
Improving compatibility
Some platforms and software only accept certain formats — converting to ICO ensures your AVIF files open everywhere they need to.
Batch migrating a library

Frequently Asked Questions
Will converting AVIF to ICO reduce image quality?
Since ICO is a lossless format, no additional quality is lost when converting your AVIF file. If the original AVIF was already compressed with quality loss, that loss can't be recovered, but nothing further is discarded.
Does ICO support transparency?
Yes, ICO supports transparency, so any transparent areas in your AVIF file are preserved in the converted image.
Is it safe to convert AVIF files to ICO here?
Yes. The whole AVIF to ICO conversion runs locally in your browser using the Canvas API — your AVIF files are never uploaded to a server.
Can I convert several AVIF files to ICO at once?
Yes, drop multiple AVIF files at once and click Convert All — each one is converted to ICO and can be downloaded individually or as a ZIP.
What sizes are included in the ICO file?
The output ICO bundles three resolutions — 16×16, 32×32, and 48×48 — generated from your AVIF source in a single file, ready to use as a favicon or app icon.
Is there a size limit for AVIF uploads?
There's no hard limit set by Pixvert for AVIF files, but very large files depend on your device's available memory to convert smoothly.
Can I use the ICO output commercially after converting?
Yes, converting AVIF to ICO only changes the file format — it doesn't alter your rights over the image or add a watermark.
