Frequently asked questions
Why convert JPG to AVIF?
AVIF can produce smaller web images at comparable visual quality, helping reduce page weight in browsers that support it.
Does conversion improve image quality?
No. It preserves the visible source as well as possible but cannot restore detail already lost to JPEG compression.
What quality should I choose?
Around 75–85% is a practical starting point. Inspect fine textures and text before using lower settings.
