This conversion needs a HEIF/HEVC codec that is not available in this browser engine yet.
HEIC 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.
HEIC and PNG 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 PNG 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.
PNG compression is lossless. Palette conversion, resizing or reducing bit depth before encoding can still discard information. Animation is the APNG extension included in the third edition. PNG can store its supported image samples without lossy compression. This applies after rendering and sample conversion: it does not guarantee preservation of source precision, colour space or document structure, and cannot undo earlier losses.

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

Portable Network Graphics
Lossless raster images with precise edges and optional transparency. The PNG standard also defines APNG animation.

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.
HEIC: Exif, XMP, ICC, NCLX → PNG: Exif, ICC, Text. Which fields are copied, rewritten or omitted will depend on the future engine; retention is not implemented yet.
