Works in every browser
Most “AVIF converters” rely on the browser’s encoder, which only exists in Chrome. Dropsize uses a WebAssembly AVIF encoder, so it produces AVIF the same way in Chrome, Firefox and Safari.
When to use AVIF
Use AVIF when you want the smallest files and your audience is on modern browsers (widely supported since 2024). For maximum compatibility with old software, keep a WebP or JPEG copy.
