PDFixel compiles the official `libheif` C++ library to WebAssembly, decoding 10-bit and 12-bit High Efficiency Image Container streams with full color fidelity directly on your hardware.

HEIC wraps its image data in HEVC, a patent-encumbered video codec, and that licensing is why broad native support never arrived outside Apple's own platforms. Safari on Apple hardware decodes HEIC because the system codec is already licensed there; other browsers do not ship a decoder at all. Converting is therefore not a workaround for a missing feature — it is the practical way to make an iPhone photo openable everywhere, which is exactly why a WebAssembly decoder is needed to do it in a browser.

For ordinary photographs, JPG. HEIC photos are photographic content and PNG stores that very inefficiently — expect a file several times larger with no visible benefit, because the HEIC was already lossy and PNG cannot restore what it discarded. Choose PNG when you specifically need a lossless working copy for editing, or transparency, or when a system you are uploading to accepts only PNG. Otherwise HEIC to JPG is the right tool.

Converting to PNG does not add any further loss — PNG stores exactly what the decoder produced. Two things are still worth knowing. The HEIC itself is lossy, so its own compression is baked into what you get. And HEIC can hold 10-bit colour depth, while PNG output here is 8-bit per channel, so a photo with extremely subtle gradients can show marginally less tonal precision. Neither is visible in normal viewing.
