    Why You Should Convert to AVIF?

    The web is getting faster, and image formats are evolving. AVIF (AV1 Image File Format) is the modern successor to JPEG, PNG, and even WebP. It offers superior compression efficiency without sacrificing quality, which is critical for passing Google's Core Web Vitals assessment (specifically LCP).

    AVIF vs. WebP vs. JPEG

    Why switch? Here is the breakdown:

    • Smaller Size: AVIF files are typically 50% smaller than JPEGs and 20-30% smaller than WebP files of the same quality.
    • Better Quality: AVIF supports 10-bit and 12-bit color depths, HDR, and fewer compression artifacts (blocking) than JPEG.
    • Transparency: Like PNG and WebP, AVIF fully supports transparent backgrounds.

    Client-Side Privacy

    Most online converters require you to upload your personal photos to a remote server to process them. This is slow and risky.

    The GungorKaya.com AVIF Converter is different. It runs 100% in your browser using modern HTML5 technology. Your photos never leave your device. You can convert 1 or 100 images instantly, even without an internet connection.
