How do I convert SVG to AVIF?

Upload your SVG file above. It is converted to AVIF automatically (change the output format or quality in the Settings tab if you need to), then click Download. There is nothing to install.

Does converting SVG to AVIF lose quality?

AVIF is lossy by default, so some fine detail is discarded to make the file smaller. Raise the quality or switch on lossless in Settings for a closer copy.

Will the AVIF keep the transparent background?

Yes. AVIF supports smooth, partial transparency, so transparent areas stay transparent.

SVG or AVIF: which should I use?

Use SVG for logos, icons and illustrations that must stay sharp at any size. Use AVIF for the smallest high-quality images for websites and apps. Keep in mind the main drawback of AVIF: it is slow to create and many editing apps and older devices can't open it.
