5 Best Ways to Convert PNG to AVIF and Save 50% More Space

AVIF images are super helpful because they solve a big problem today: the need to save space on our phones and computers.

AVIF saves 50% or more storage than PNG or JPG formats.

This way, you can save a lot of space and keep all your favorite pictures.

But there’s a new problem! You need to convert the PNG images to AVIF images.

That sounds like a lot of work, right?

Don’t worry, though! We know a lot about making AVIF images and can help you convert PNG to AVIF images.

In this article, we’ll show you how to convert PNG pictures to AVIF images.

What Is an AVIF Image File?

AVIF (AV1 Image File) is a modern image format based on the AV1 HEIF image compression technology.

Alliance for Open Media created AVIF image files in search of a higher-quality image format that doesn’t take up a lot of space – it’s half the size of other image formats such as JPG or PNG.

AVIF is notably efficient in compressing high-quality images into smaller file sizes, including HDR and animated pictures. It even supports GIF animations, making it versatile for image needs.

AVIF’s support for various color depths – 8, 10, and 12-bit – and its ability to preserve film grain and provide transparency similar to PNG images.

Only 1% of websites use AVIF images. However, this figure is rising as major browsers such as Chrome, Mozilla, and Safari begin to support this format.

If you’re looking for a single image format that combines JPG’s flexibility, PNG’s transparency, and GIF’s animation capabilities, AVIF is the way.

Why Would You Convert PNG to AVIF Images?

PNG is one of the most advanced image formats. But, the latest AVIF image format outperforms it in many ways. Using AVIF benefits you in many ways.

Smaller file size: AVIF has much smaller file sizes than PNG while maintaining comparable image quality. It can speed up webpage loading since images contain 21% of the page’s weight.

Efficient compression: Both PNG and AVIF support lossy and lossless compression. AVIF compresses 50% more than PNG while maintaining quality.

Animation: PNG is a static image format. Although you can use PNG for animation, it’s less effective than AVIF. The AV1-based AVIF codec stores image sequences efficiently.

Improves user experience: AVIF doesn’t do progressive rendering. Instead, it shows lower-quality preview images before file decoding. It improves user experience because the browser no longer downloads the entire image before decoding.
