AVIF
Source
AVIF
AV1 Image File Format
Compression: Lossy & losslessTransparency: YesMetadata: Exif, XMP, ICC, CICP
AV1-compressed pictures in an image container, with optional alpha, sequences and high-dynamic-range colour.

Target
HEIC
High Efficiency Image File Format (HEVC)
Compression: Lossy & losslessTransparency: YesMetadata: Exif, XMP, ICC, NCLX
HEVC-coded photographs in HEIF, with room for auxiliary images and capture metadata.

Good choice when
- HEIC fits your delivery use: Device photography & image collections.
- Your destination supports the required animation variant.
- You need HDR-capable delivery and can validate its encoding and colour signalling.
- You need a transparency-capable destination and will check its supported variant.
Probably not when
- You require animation, HDR or auxiliary alpha preservation; this native still-image path does not provide it.
- You require guaranteed scene-linear values or HDR appearance.
- You assume format-level alpha support guarantees matching transparent edges.
- You need a guaranteed output file size or archival pixel equality. Encoder settings do not guarantee either.

- HDR display encoding
- Creates a lossy, opaque 8-bit sRGB HEIC using this device’s native encoder. Original P3/HDR precision is not retained. Availability is checked on this device using native WebCodecs.
- Transparency representation
- Transparency is replaced with white by default. Change the background in Advanced options. Creates a lossy, opaque 8-bit sRGB HEIC using this device’s native encoder. Original P3/HDR precision is not retained.
- Encoding mode
- Creates a lossy, opaque 8-bit sRGB HEIC using this device’s native encoder. Original P3/HDR precision is not retained.
- Sample precision & colour
- Creates a lossy, opaque 8-bit sRGB HEIC using this device’s native encoder. Original P3/HDR precision is not retained. Availability is checked on this device using native WebCodecs.
- Metadata & colour
- Creates a lossy, opaque 8-bit sRGB HEIC using this device’s native encoder. Original P3/HDR precision is not retained. Availability is checked on this device using native WebCodecs.
- Compression
- AVIF: Lossy & lossless → HEIC: Lossy & lossless AVIF: AVIF can use lossy or lossless AV1 coding. Chroma subsampling, RGB↔YUV conversion and reduced bit depth can change source values even when the AV1 coding stage is lossless. HEIC: HEIC commonly uses lossy HEVC; HEVC also has lossless coding tools. Actual quality, bit depth and chroma depend on the encoded profile and settings, not on the .heic extension.
- Transparency
- Transparency is replaced with white by default. Change the background in Advanced options. Creates a lossy, opaque 8-bit sRGB HEIC using this device’s native encoder. Original P3/HDR precision is not retained.
- Animation
- Still image output. Animated files use only the first frame; animation is not preserved.
- Colour depth
- Creates a lossy, opaque 8-bit sRGB HEIC using this device’s native encoder. Original P3/HDR precision is not retained.
- HDR
- Creates a lossy, opaque 8-bit sRGB HEIC using this device’s native encoder. Original P3/HDR precision is not retained. Availability is checked on this device using native WebCodecs.
- Multiple images
- Creates a lossy, opaque 8-bit sRGB HEIC using this device’s native encoder. Original P3/HDR precision is not retained.
- Dimensions
- Rendered image dimensions are retained within the converter limits; this tool does not offer resizing. Orientation handling depends on the source decoder.
- Metadata
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
