This conversion needs a HEIF/HEVC codec that is not available in this browser engine yet.
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.
An animated HEIF has a timed sequence; PBM 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.
PBM represents each pixel as black or white. Colour and intermediate gray levels cannot survive as sample values. Thresholding or dithering decides how tones become marks; the future engine has no such policy yet. PBM is not an ordinary grayscale photograph format.
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. PBM 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.

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.
HEIF: Exif, XMP, ICC, NCLX → PBM: Header, Comments. Which fields are copied, rewritten or omitted will depend on the future engine; retention is not implemented yet.
