Will I lose quality converting to AVIF?
AVIF uses lossy compression, so the image is re-encoded at high quality (92%). For photos the difference is practically invisible; for text-heavy graphics or logos, a lossless format like PNG preserves sharp edges better.
Is transparency kept when converting to AVIF?
Yes — AVIF supports an alpha channel, so transparent areas are preserved.
