Why convert ICO to AVIF?
ICO and AVIF handle compression differently — check the comparison below before you convert anything you can't re-export from the original. The main reason to convert ICO to AVIF is compatibility: AVIF opens in every browser, image viewer and design tool without a plugin, while ICO doesn't always. If you're sharing a file with someone else, sending it to a tool that expects a specific format, or archiving it for the long term, AVIF is usually the safer target.
Format comparison
| ICO | AVIF | |
|---|---|---|
| Extension | .ico | .avif |
| MIME type | image/x-icon | image/avif |
| Compression | lossless compression | either lossy or lossless compression, depending on settings |
| Category | image | image |
Common reasons to convert ICO to AVIF
- Uploading to a website builder, ad network or CMS that only accepts AVIF
- Shrinking page load time with a more compressible file than the ICO original
- Standardizing on one format so every file behaves the same way in your workflow
Your file, handled carefully
Uploads use TLS in transit and AES-256 SSE-S3 at rest in production (when the production S3 credential gate is enabled), are processed in an isolated job, and deleted on the schedule you choose — as fast as immediately. We don't index, search, or share files between accounts. Read the full security model →
