What to expect from ICO to AVIF
What changes in the file, and what to check before you share the result.

ICO to AVIF questions
Short answers about limits, privacy, and keeping the converted file.
Do browsers support AVIF?
All current major browsers display AVIF. Some older browsers, email clients, and desktop programs do not, so keep a JPG or WebP fallback where that matters.
Is the ICO to AVIF converter free?
Yes. Without an account you can convert up to 10 files a day, 2 at a time, up to 25 MB each. A free account adds monthly conversion credits and larger files.
How long are my files kept?
Guest uploads and results are deleted automatically after 1 hour. Conversions stay temporary when you are signed in too, unless you save a result to your workspace.
Can I get a permanent link to the AVIF file?
Yes. Save the result to a SteadyLink workspace and it gets a stable link. If you make a new version later, replace the file and the link stays the same.
