PNG to AVIF Converter
PNG keeps images perfectly sharp but its lossless approach can leave you with hefty file sizes. AVIF is the newest mainstream image format and offers best-in-class compression, often shrinking files dramatically while keeping them visually identical. Converting PNG to AVIF is a smart move when you want the smallest possible files for the modern web.

Why use this converter?
AVIF is perfect for performance-focused websites, image-heavy galleries, and anyone who wants to cut bandwidth costs without visible quality loss. It supports transparency, so your PNG’s alpha channel is retained in the output. The conversion runs entirely inside your browser, so nothing is installed and your images are never sent to a server. Because AVIF encoding is still rolling out, this tool feature-detects your browser and offers AVIF export only when your device can encode it, showing a graceful note if support is unavailable. Use the quality slider to dial in exactly the balance you want between size and detail.

Frequently asked questions
Is the PNG to AVIF converter free?
Yes, it is entirely free. There are no watermarks, no sign-up, and no caps on the number of files you can convert.
Is my file private and secure?
Completely. Your file is processed 100% inside your browser using the Web APIs built into your device. Nothing is uploaded to any server — imgic never sees, stores, or transmits your images. You can even use these tools offline once the page has loaded.
Why is AVIF sometimes unavailable?
AVIF encoding depends on your browser. This tool feature-detects support and only offers AVIF export when your device can create it; otherwise it shows a friendly note so you are never left guessing.
What is an AVIF file?
AVIF (AV1 Image File Format) is a modern image format built on the AV1 video codec. It offers some of the best compression available today, supports transparency and HDR, and keeps images looking great at very small sizes.
Does AVIF keep my PNG transparency?
Yes. AVIF supports an alpha channel, so transparent regions in your PNG are preserved in the converted file.
