If AVIF conversion fails, your browser may not support AVIF encoding. Try WebP instead.
Converting PNG with transparency to JPG will result in a white background.
For large batches, conversion may take a few seconds on older devices.

Pro Tips for Creators

Convert PNG images to WebP for web use — you'll typically get 50-80% smaller files.
Use PNG output when you need to preserve transparency for logos and UI elements.
AVIF offers the best compression but has limited support in older browsers — check caniuse.com first.
