Will transparent pixels stay transparent?

PixSip keeps the alpha channel in AVIF output. The app that opens the file must also support AVIF transparency.

Is AVIF always smaller than PNG?

No. The result depends on the image. Photographic PNG files often have more room to shrink than simple already optimized graphics.

No. Keep the PNG until you have verified every destination that will consume the AVIF file.

Yes. Decoding and AVIF encoding run in the browser.

Turn transparent PNG assets or photographic PNG files into AVIF on your device, then inspect the result before you replace the original.

Check compatibility
Compare the result, keep the PNG source, and download AVIF only for supported destinations.

The conversion keeps alpha data, but the destination app must also support transparent AVIF.

Use the 1:1 comparison for text edges, logos, and soft shadows.

PNG remains the safer choice for older editors, email clients, and upload forms.
