Is my data uploaded to a server?

No. All conversion happens in your browser using the Canvas API. Your files never leave your device.

My browser says AVIF is not supported — what do I do?

AVIF encoding requires Chrome 94+ or Firefox 93+. Update your browser or use our PNG to WebP converter as an alternative, which has near-universal support.

Does AVIF support transparency?

Yes. AVIF supports an alpha channel, so transparent PNGs will retain their transparency when converted to AVIF.

What quality setting should I use?

Quality 75–85% gives an excellent balance of visual quality and file size. For photographic images, 60–70% is often sufficient. Use higher values for images with text or sharp edges.

Why Convert PNG to AVIF?

AVIF (AV1 Image File Format) is a modern image format developed by the Alliance for Open Media. It offers significantly better compression than PNG, WebP and even JPEG — often 50% smaller at the same visual quality. It's ideal for web images where bandwidth and load time matter.
