AVIF to Base64 converts an AV1 Image File Format (AVIF) file to a Base64-encoded string and data URI in your browser. AVIF is a modern image format offering excellent compression. Embedding as Base64 avoids a separate HTTP request, useful for inline styles, email templates, or single-file HTML pages.
