Good choice when
- HEIC fits your delivery use: Device photography & image collections.
- You need a transparency-capable destination and will check its supported variant.
- Your receiving application supports the required HEIC variant.
- You can validate the destination’s sample precision and colour interpretation.
Probably not when
- 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.
- You require identical samples without a defined colour and precision policy.

- Compression
- QOI: Lossless → HEIC: Lossy & lossless QOI: QOI preserves 8-bit RGB/RGBA samples losslessly. Reducing 16-bit data or discarding profiles and metadata before encoding is outside that guarantee. 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.
