Why Convert HEIC to AV1?
HEIC is Apple's default photo format since iOS 11, offering excellent quality at small file sizes. AV1 is the most efficient video codec available — royalty-free, supported by all major browsers, and delivering ~30% better compression than H.265. Converting HEIC photos to AV1 video creates ultra-compact slideshows and timelapses from your iPhone/iPad photo library.
This is ideal for creating timelapses from burst photos, building portfolio reels from iPhone photography, or sharing photo collections as video on platforms that support AV1 streaming.

| H.264 (MP4) | Good | Universal | Licensed | Maximum compatibility |

Frequently Asked Questions
Can I merge multiple HEIC photos into one video?
Yes. Upload multiple HEIC files and select "Merge images." Set the duration per image to control playback speed. Photos play in upload order.
What resolution should I use?
For web sharing, 1080p is standard. iPhone photos are typically 4032×3024 (12MP) or 4284×5712 (48MP) — "Keep original" preserves full resolution but produces large files.
Can I create a timelapse from iPhone burst photos?
Yes. Upload your HEIC burst sequence, select "Merge images," and set a short duration (0.1–0.5 seconds per frame) for timelapse playback.
Is AV1 supported everywhere?
AV1 is supported in Chrome, Firefox, Safari (17+), and Edge — over 90% of web users. For maximum compatibility, consider HEIC to MP4.
Will converting lose the HEIC quality?
The HEIC image data is decoded and encoded into AV1 video frames. At high quality settings, the visual difference is negligible. HEIC's 10-bit color depth is preserved in AV1's HDR support.
