PNG to AVIF

Why convert PNG to AVIF?

The main difference: PNG is a lossless format, while AVIF is a lossy or lossless format.

Smaller files, faster uploads

AVIF supports lossy compression, so your file typically ends up a fraction of the PNG size - quicker to attach to an email, upload to a form or load on a web page.

Transparent areas stay transparent

PNG and AVIF both handle transparency, so anything see-through in the original is still see-through after conversion.

Lighter images for your website

At the same visual quality, AVIF files are noticeably smaller than JPG or PNG. Lighter images mean faster pages, better Core Web Vitals and a small boost for SEO.

What is a PNG file?

PNG (Portable Network Graphics) is a lossless image format created in 1996 as a patent-free replacement for GIF. It stores every pixel exactly, so text, logos and sharp edges stay perfectly crisp however often you save the file.

PNG supports full transparency, which makes it the standard format for logos, icons, screenshots and graphics placed on top of other designs. For photos, though, PNG files are several times larger than JPG.

How to open a PNG file

PNG opens everywhere: Windows Photos, Mac Preview, iPhone and Android galleries and every web browser. Editors like Photoshop, GIMP, Figma and Canva keep the transparency intact.

Extension: .png
Compression: Lossless
Transparency: Yes
Best for: Logos, screenshots, graphics, text

What is an AVIF file?

AVIF (AV1 Image File Format) is a modern image format based on the AV1 video codec, developed by the Alliance for Open Media - Google, Apple, Microsoft, Netflix and others. It typically produces smaller files than both JPG and WebP at the same visual quality.

AVIF supports transparency, HDR and wide color, which makes it a favorite for fast websites. Support outside browsers is still patchy, so downloaded AVIF files often need converting.

How to open an AVIF file

Chrome, Edge, Firefox and Safari 16+ display AVIF. Windows 11 opens it in Photos once the free AV1 Video Extension is installed; macOS Ventura and later preview it. For editors and forms that refuse it, convert to JPG or PNG.

Extension: .avif
Compression: Lossy or lossless (AV1)
Transparency: Yes
Best for: The smallest high-quality web images
