About PNG to AVIF
PNG to AVIF turns heavy PNG graphics and screenshots into AVIF files that can be a fraction of the size. AVIF supports transparency, so logos and interface images can stay see-through while taking much less space, which speeds up pages and reduces hosting costs.
Select your PNG files, choose the quality and convert. Several files are processed one after another and downloaded together as a ZIP. Browsers cannot normally write AVIF themselves, so a small encoder program may be fetched the first time you use the tool; your pictures stay on your device and are never uploaded.
No watermark is added and no account is needed. For maximum compatibility, use PNG to WebP, and for photos in older programs use PNG to JPG. To open AVIF files again, use AVIF to JPG, and for general size reduction try Compress Image.
Frequently asked questions

Which is better, WebP or AVIF?
AVIF is usually smaller, WebP is supported in more older software and encodes faster. Pick based on where the images will be used.
