Frequently Asked Questions
Is WebP better than AVIF?
Generally, AVIF offers better compression efficiency (smaller file sizes) than WebP for the same visual quality. However, WebP currently has slightly broader browser support.
Can I open WebP on iPhone?
Yes, modern iOS versions (iOS 14+) support WebP natively. If you have an older iPhone, converting to JPG is recommended.
Is it safe to convert private photos here?
Absolutely. Avifkit uses client-side processing technology. Your images are converted directly within your web browser memory and are never uploaded to any external server.
Does this tool support transparency?
Yes! If you convert AVIF to PNG or WebP, the transparent background (alpha channel) is preserved. If you convert to JPG, transparent areas will become white.
How do I open AVIF on Windows 10?
Windows 10 and 11 support AVIF if you install the 'AV1 Video Extension'. Alternatively, use Avifkit to convert them to standard JPGs.
