Why Convert PNG to AVIF?

PNG files are often very large due to lossless compression. A typical PNG screenshot might be 2-5MB, while the same image in AVIF could be under 500KB — without any visible quality loss.

FAQ

Frequently Asked Questions

Why should I convert PNG to AVIF?

PNG files are often very large due to lossless compression. Converting to AVIF can reduce file sizes by 50-80% while maintaining excellent visual quality, making your images much faster to load.

Will converting PNG to AVIF lose quality?

AVIF uses lossy compression, so some data is lost compared to the original PNG. However, at high quality settings, the difference is imperceptible for most use cases, and the file size reduction is dramatic.

What about transparency?

AVIF supports transparency (alpha channel) just like PNG. Your transparent backgrounds will be preserved during conversion.

Can I convert multiple PNG files at once?

Yes. You can drag and drop or select multiple PNG files. They'll all be converted to AVIF simultaneously, and you can download them individually or as a ZIP.

Is my data safe?

Absolutely. All conversion happens entirely in your browser. Your images are never uploaded to any server. They stay on your device from start to finish.
