Why Convert PNG to AVIF?

A PNG keeps every pixel, which is why a full-page screenshot or a photo saved as PNG can balloon past several megabytes. AVIF fixes that.

Built on the AV1 video codec, it holds the same picture in a fraction of the space, often 20 to 50 percent smaller than WebP and well under half the size of the PNG. Switch on a hero image or a photo-heavy page and you ship fewer bytes and a faster load, and since Google now indexes AVIF in image search, there's no SEO cost to it.

Frequently Asked Questions

How much smaller will the AVIF be?
For photographic PNGs, expect roughly half the size or less. For flat graphics with few colors the gain is smaller, and a tuned PNG can occasionally win. The saving depends entirely on the image content.
Should I convert logos and icons to AVIF?
Usually not. AVIF's lossy compression can soften hard edges and small text, so PNG or SVG stays the better call for logos, UI, and line art. AVIF earns its keep on photos and large detailed images.
Will every browser display the AVIF?
About 94 percent of browsers do as of 2026, including current Chrome, Firefox, Safari, and Edge. The gap is older Android and some legacy enterprise browsers, so keep a fallback if you serve the public.
Does AVIF keep the PNG's transparency?
Yes. AVIF supports an alpha channel, so transparent areas in your PNG carry over intact.
Is this conversion free, and is my file private?
Yes. The conversion runs in your browser tab, nothing is uploaded, and no account is needed. The only limit is size: 25 MB for this format. Bigger files route to the desktop app.

Re-encoding a whole image folder to AVIF?

The browser does one file at a time. TeraConvert Desktop converts a full folder of PNGs to AVIF in one run, with no 25 MB cap.
