Frequently asked questions
Why should I care about image compatibility?
If you use modern formats like AVIF or HEIC on your website without fallbacks, users on older browsers or specific operating systems will see broken images instead of your content.
Are WebP images safe to use everywhere?
Mostly, yes. WebP has excellent support across all modern browsers. However, it is not supported in Internet Explorer 11, and requires macOS 11+ for desktop Safari users.
What is AVIF?
AVIF is a next-generation image format offering better compression than WebP. Its browser support is growing but still lacks universal adoption, especially on older iOS and macOS devices.
Why can't I use HEIC on my website?
HEIC (or HEIF) is a proprietary format used natively by Apple devices. It is not supported by Chrome, Firefox, Edge, or Android browsers, making it unsuitable for general web use.
Does this tool upload my images?
No. The compatibility detection and subsequent format conversion happen entirely within your browser for maximum privacy and speed.
Which format is best for a website?
Use the format your browser and content pipeline support: WebP or AVIF for many web photos, PNG for transparency, and JPEG for broad compatibility with photographs.
Should I provide a fallback image?
Yes, a fallback is sensible when your audience may use older browsers. The picture element can serve modern formats first and a widely supported format when needed.
