What happens when you convert HEIF to JPEG XL?

Multiple source images

Primary SDR still image only. sRGB/Display P3 and supported 8/10-bit HEVC render to 8-bit sRGB. HDR, auxiliary alpha and other HEIF codecs are rejected. Thumbnails, depth, gain maps and Live Photo motion are not exported. Availability is checked on this device using native WebCodecs.

Animation-capable destination

Still image output. Animated files use only the first frame; animation is not preserved.

HDR display encoding

Encoding mode

Lossless pixels, lossy pixels and reversible recompression of an eligible JPEG bitstream are separate modes. Exact JPEG reconstruction requires its reconstruction data, not just matching rendered pixels. Quality defaults to 80; adjust it in Advanced options. File size depends on the image and encoder.

HEIF

High Efficiency Image File Format

Compression: Depends on variantTransparency: YesMetadata: Exif, XMP, ICC, NCLX

Is HEIF → JPEG XL right for you?

Good choice when

JPEG XL fits your delivery use: High-precision photographic storage.
You can choose the source image or part needed for delivery.
Your destination supports the required animation variant.
You need HDR-capable delivery and can validate its encoding and colour signalling.

Probably not when

You require a complete collection, page set or multipart round trip.
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.

Conversion considerations

HEIF can contain multiple image representations with different roles. These are not automatically a timed animation. Selecting an image, preserving a collection or creating several outputs needs explicit engine support; neither a first-image choice nor an all-images export is implemented.
HEIF and JPEG XL can represent image animation, but their frame structures are not interchangeable. Retaining motion requires sequence decoding, compositing, timing and loop mapping plus an animation-aware encoder. No such transfer is implemented; a still-only pipeline would lose the sequence.
The source can carry HDR information and JPEG XL has HDR-capable variants. Working radiometric values and display-referred HDR are different representations. Range, primaries, transfer function and signalling must be mapped explicitly; the future engine may instead produce SDR. HDR preservation is not promised by format support.

Thumbnails, depth, gain maps and Live Photo motion are not exported. Availability is checked on this device using native WebCodecs.
Animation-capable destination: Still image output. Animated files use only the first frame; animation is not preserved.
HDR display encoding: Primary SDR still image only. sRGB/Display P3 and supported 8/10-bit HEVC render to 8-bit sRGB. HDR, auxiliary alpha and other HEIF codecs are rejected. Thumbnails, depth, gain maps and Live Photo motion are not exported. Availability is checked on this device using native WebCodecs.
Transparency representation: Primary SDR still image only. sRGB/Display P3 and supported 8/10-bit HEVC render to 8-bit sRGB. HDR, auxiliary alpha and other HEIF codecs are rejected. Thumbnails, depth, gain maps and Live Photo motion are not exported.
Encoding mode: Lossless pixels, lossy pixels and reversible recompression of an eligible JPEG bitstream are separate modes. Exact JPEG reconstruction requires its reconstruction data, not just matching rendered pixels. Quality defaults to 80; adjust it in Advanced options. File size depends on the image and encoder.
Sample precision & colour: Primary SDR still image only. sRGB/Display P3 and supported 8/10-bit HEVC render to 8-bit sRGB. HDR, auxiliary alpha and other HEIF codecs are rejected. Thumbnails, depth, gain maps and Live Photo motion are not exported. Availability is checked on this device using native WebCodecs.
Metadata & colour: Primary SDR still image only. sRGB/Display P3 and supported 8/10-bit HEVC render to 8-bit sRGB. HDR, auxiliary alpha and other HEIF codecs are rejected. Thumbnails, depth, gain maps and Live Photo motion are not exported. Availability is checked on this device using native WebCodecs.
Compression: HEIF: Depends on variant → JPEG XL: Lossy & lossless HEIF: HEIF defines the container. Compression may be lossy, lossless or uncompressed depending on its codec binding; one global quality or bit-depth value would be misleading. JPEG XL: Lossless pixels, lossy pixels and reversible recompression of an eligible JPEG bitstream are separate modes. Exact JPEG reconstruction requires its reconstruction data, not just matching rendered pixels.
Transparency: Primary SDR still image only. sRGB/Display P3 and supported 8/10-bit HEVC render to 8-bit sRGB. HDR, auxiliary alpha and other HEIF codecs are rejected. Thumbnails, depth, gain maps and Live Photo motion are not exported.
Animation: Still image output. Animated files use only the first frame; animation is not preserved.
Colour depth: Primary SDR still image only. sRGB/Display P3 and supported 8/10-bit HEVC render to 8-bit sRGB. HDR, auxiliary alpha and other HEIF codecs are rejected. Thumbnails, depth, gain maps and Live Photo motion are not exported.
HDR: Primary SDR still image only. sRGB/Display P3 and supported 8/10-bit HEVC render to 8-bit sRGB. HDR, auxiliary alpha and other HEIF codecs are rejected. Thumbnails, depth, gain maps and Live Photo motion are not exported. Availability is checked on this device using native WebCodecs.
Layers: JPEG XL: Frame blending; not PSD editing
Multiple images: Primary SDR still image only. sRGB/Display P3 and supported 8/10-bit HEVC render to 8-bit sRGB. HDR, auxiliary alpha and other HEIF codecs are rejected. Thumbnails, depth, gain maps and Live Photo motion are not exported.
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.
