Not Ideal for Logos and Sharp Graphics

PNG's lossless compression is perfect for logos. AVIF is lossy and may introduce subtle artifacts in solid colors and sharp edges.

Always Provide PNG Fallback

For web use, provide PNG as a fallback for browsers that do not support AVIF.

Test Quality Before Mass Converting

Convert a few images and check quality before batch converting your entire image library.
