How to convert ICO to AVIF

Choose files or drag them into the window — several at once is fine.
Make sure AVIF is selected next to the title; set the quality and size if needed.
Click “Convert” and download the result. Several files come as one ZIP archive.

ICO is the format for Windows icons and website favicons.

AVIF is the most compact modern format. Browsers support it, office software does not.

Which quality to choose

85 is optimal for most tasks. 95–100 is for printing and further editing. 60–75 is for messengers and websites with upload size limits.

Is it safe?

Files are processed on a server in Russia and are not stored: they are deleted from memory right after conversion. Metadata — location, phone model, capture date — is removed by default.
