How do I convert HEIC to AVIF?

Upload your HEIC image, set the quality slider (lossless or 80% for web), and click Convert. Our tool encodes the image to AVIF using AV1 codec. Once done, download the AVIF file to your device. HEIC files with alpha channels are supported; the resulting AVIF will retain transparency.

Why should I convert HEIC to AVIF?

HEIC is a high-efficiency container based on HEVC, commonly used on Apple devices. AVIF uses the AV1 codec, which provides up to 50% better compression at the same quality and is natively supported in all modern browsers. Converting reduces file size while preserving quality, making AVIF ideal for web publishing, storage, and cross-platform sharing.

What happens to metadata and color when converting HEIC to AVIF?

Our converter preserves EXIF, XMP, and GPS metadata by default. Color profiles are converted from HEIC's Display P3/sRGB to AVIF's ICC profile-compatible space. For lossless mode, pixel data is stored without compression artifacts; lossy mode applies AV1's high-efficiency compression. Transparency (alpha channel) is retained, and HDR levels are either preserved or mapped depending on output settings.
