No. All conversion happens 100% in your browser using WebAssembly. Your images never leave your device — zero server uploads, complete privacy.
Is AVIF smaller than WebP for PNG images?
Usually yes. AVIF typically produces files about 20% smaller than WebP and up to 50% smaller than PNG at comparable quality, especially for photographic content.
Does AVIF support transparency like PNG?
Yes. AVIF supports an alpha channel, so transparent PNGs stay transparent. It also supports HDR and wide color gamut, which PNG handles less efficiently.
