AVIF vs HEIF Comparison

AVIF

Based on AV1 video codec, offering excellent compression (often better than HEIF). Widely supported in browsers like Chrome, Firefox, and Safari. Great for web use but limited native OS support. Consider our AVIF to WebP converter for web optimization.

HEIF/HEIC

Apple's preferred image format since iOS 11 and macOS High Sierra. Uses HEVC codec for compression. Native support on all Apple devices with excellent quality-to-size ratio. The .heic extension is Apple's naming, while .heif is the standard. See our HEIC to JPG for broader compatibility.

Why Convert AVIF to HEIF?

Apple Device Compatibility

HEIF is natively supported on iPhone, iPad, and Mac. Share images directly without conversion needed on the receiving end.

Photos App Integration

HEIF files work seamlessly with Apple Photos, iCloud Photo Library, and all native iOS/macOS image editors.

Excellent Compression

Both formats offer superior compression compared to JPEG. HEIF maintains excellent quality while keeping files small.

AirDrop Ready

HEIF files transfer perfectly via AirDrop between Apple devices without any compatibility issues or automatic conversion.

Quality Settings Guide

90-100%

Maximum quality with minimal compression. Best for archiving, professional photography, and when file size isn't a concern. Use our Image Upscaler first if you need higher resolution.

75-89%

Excellent balance of quality and file size. Recommended for most uses including photo sharing, social media, and general storage.

50-74%

Noticeable compression but still good for web thumbnails, previews, and when storage space is limited. Check results with our HEIC File Viewer.
