APNG Browser Support
APNG support is solid across modern engines. Legacy edge cases mostly involve old Internet Explorer environments.
Compatibility matrix
| Browser | Engine | Status | Notes |
|---|---|---|---|
| Chrome | Blink | Supported | Stable support in modern desktop and Android releases. |
| Edge | Blink | Supported | Follows Chromium implementation behavior. |
| Firefox | Gecko | Supported | Longstanding native APNG rendering support. |
| Safari | WebKit | Supported | Supported on recent macOS and iOS versions. |
| Opera | Blink | Supported | Inherits Chromium APNG behavior. |
| Internet Explorer | Trident | Not supported | Use static PNG fallback for legacy IE targets. |
Implementation guidance
- Keep APNG as the default for modern browsers and quality-first assets.
- Provide a static PNG fallback for legacy rendering targets.
- Use animated WebP alternatives when transfer size is your top metric.
