Camera RAW requires full image development. This browser engine does not implement it yet.
Canon CR2 needs camera- and file-aware development to produce a rendered HEIC image. White balance, exposure, camera colour interpretation and, where applicable, demosaicing determine that rendering. The destination does not retain the original RAW development latitude. No development settings or camera support are implemented yet.
The target can store an alpha channel, but converting an opaque image does not create transparent areas. Removing a background is a separate editing step.
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. HEIC permits different encoding modes or container representations. Its format name alone does not promise lossless output, a quality setting or a size reduction. The future engine must choose a supported codec and sample representation; inspect the target’s compression notes below.

High Efficiency Image File Format (HEVC)
HEVC-coded photographs in HEIF, with room for auxiliary images and capture metadata.

Source and target sample models can differ in precision, channel layout, colour space and transfer function. Lossless compression only preserves the samples actually encoded; a precision reduction or colour conversion can already change them. The future engine defines numeric mapping, orientation and colour conversion; canonical depth facts are listed below where available.
