How to Convert PNG to AVIF?

Upgrade your images to the most efficient format on the web. Keep your transparency, lose the file weight.

1

Upload PNGs

Drag and drop your PNG files onto the converter. You can convert up to 3 images at once for free.

2

Set Quality

Choose 'Lossless' to keep every detail, or optimize for speed and size with 'Balanced'. Our engine handles the rest.

3

Download AVIF

Get your ultra-compressed AVIF files instantly. Download them individually or grab them all in a ZIP.

Why AVIF?

AVIF offers significantly better compression than WebP and JPG while supporting transparency, HDR, and wide color gamuts. It's the future of web images.

Engineering Philosophy

Beyond Compression.
The AVIF Revolution.

PNGs are reliable, but heavy. AVIF is the next-generation codec that combines the transparency support of PNG with the compression efficiency of video codecs like AV1. At RiseConvert, we've built a pipeline to harness this power.

Our engine doesn't just transcode; it intelligently maps the alpha channel, ensuring your transparent backgrounds are preserved with pixel-perfect accuracy while reducing file size by up to 80%.

We operate on a strict "Verify & Vanish" security model. Your graphics are processed in secure, ephemeral environments that are destroyed immediately after conversion. We don't keep your files, we just improve them.

Crafted by Ex-SaaS Engineers

Ephemeral Containers

Files processed in isolated sandboxes that self-destruct post-conversion.

Smart Alpha

Advanced algorithms for flawless transparency preservation.

HDR Ready

Supports high dynamic range color spaces

Is AVIF Better than PNG?

Yes, for the web. While PNG is excellent for editing and archiving due to its lossless nature, it is inefficient for delivery.

AVIF (AV1 Image File Format) typically produces files that are 50% smaller than JPEG and up to 30% smaller than WebP, all while maintaining excellent visual fidelity and supporting alpha transparency.

How we handle transparency

One of the biggest challenges in converting PNG to newer formats is keeping the background transparent. Our tool:

  • Detects Alpha Channels: Automatically identifies transparent regions.
  • Preserves Edge Detail: Ensures there are no jagged halos around your subject.
  • Optimizes for size: Encodes the transparency efficiently so it doesn't bloat the file.

Key Terminology

AV1 Codec

The open, royalty-free video coding format that powers AVIF images.

Lossless Conversion

Compressing data without removing any details. AVIF supports this for PNG-like quality.

Artifacts

Distortions seen in compressed images. AVIF handles these much better than JPEG.

Bit Depth

AVIF supports up to 12-bit color depth, allowing for richer colors and HDR.

Pro Tips for Best Results

Use <picture> Tag

For maximum compatibility, use the HTML picture tag to serve AVIF to modern browsers and fall back to PNG/JPG for older ones.

Frequently Asked Questions

What is the advantage of converting PNG to AVIF?
The main advantage is file size. AVIF files can be significantly smaller than PNGs while maintaining transparency and high quality, which speeds up your website.
Is it free to use?
Yes, RiseConvert is free for all users. You can convert multiple files without any cost.
Does AVIF support transparency like PNG?
Yes! AVIF fully supports alpha channels, meaning your transparent backgrounds will remain transparent after conversion.
Will the quality decrease?
It depends on your settings. 'Lossless' mode preserves original quality perfectly. 'Balanced' introduces some imperceptible compression to reduce file size further.
How secure is this tool?
Extremely secure. We use 256-bit SSL encryption for data transfer and our servers automatically delete your files after 2 hours.
Which browsers support AVIF?
Most modern browsers like Chrome, Firefox, and Opera support AVIF. Safari added support in iOS 16 and macOS Ventura.
