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.
An animated HEIC has a timed sequence; PPM is a still-image destination in this workflow. A still export loses motion and timing. Frame choice, blending and disposal must be defined by the future engine; a first-frame export is not promised.
If HDR source content is exported through an SDR representation, it needs a display rendering. Values outside the output range require tone mapping, scaling or clipping; brightness relationships can change. Tone mapping, exposure and colour handling depend on the future engine. Renaming or lossless compression cannot preserve out-of-range values.
Netpbm stores these samples without compression. Reducing colour, thresholding or changing maxval can still lose information before storage; text and binary representations change the layout, not its image meaning. PPM 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.

Renaming or lossless compression cannot preserve out-of-range values.
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 → PPM: Header, Comments. Which fields are copied, rewritten or omitted will depend on the future engine; retention is not implemented yet.
