PNG to AVIF Converter Free Online - Pro Transparency
Convert PNG to AVIF Free — Dramatically Smaller Web Images
PNG files are lossless and large. AVIF can represent the same image at 50–60% smaller file sizes while remaining visually identical on screen. For web developers and designers publishing images online, converting PNG to AVIF is one of the best performance optimizations available today. Our free PNG to AVIF converter works entirely in your browser.
Why AVIF Beats PNG for Web Use
Smaller files, faster pages: AVIF is significantly smaller than PNG, which means faster load times for users. Transparency support: Unlike JPG, AVIF preserves transparent backgrounds — so logos, icons, and product cutouts work perfectly. Better than WebP too: AVIF typically achieves 20–30% smaller files than WebP at the same visual quality. Google loves fast pages: Images are often the largest elements on a page; smaller images directly improve Core Web Vitals scores.
When to Keep PNG
If the image will be edited further, or if you need it to work in desktop software like Photoshop without plugins, keep the PNG. AVIF is ideal for web delivery but not yet universally supported by editing tools.
Private, Free, Unlimited

Frequently Asked Questions
How much smaller will the AVIF be compared to my PNG?
Typically 50–70% smaller. The reduction depends on image content — photographs compress more aggressively than flat graphics.
Will the transparent background in my PNG be preserved?
Yes. AVIF supports alpha transparency, so your transparent logos and icons convert without any white fill.
Can I open the AVIF in Photoshop?
Photoshop 2023 and later supports AVIF. Older versions require a plugin. For the widest software compatibility, keep the PNG version as a backup.
