Convert GIF to APNG

A GIF is being reworked for a website and its jagged transparent edges look wrong on anything other than the background it was made for.

    What actually changes

    GIF and APNG are not the same picture in two wrappers.

    Each frame is expanded from indexed colour to full RGBA and stored as PNG frames inside an APNG stream. Timing and looping are preserved. The result can hold soft alpha edges that GIF never could.

    Worth knowing first

    The conversion does not recover colours the GIF already discarded, and it cannot invent soft edges where the GIF stored a hard cutout. You get a container that could hold better data, filled with the data the GIF had.

    Questions

    GIF to APNG, answered

    Why bother if the quality is the same?

    Future edits. Once the animation is APNG you can composite it over any background and re-export without fighting the 256-colour palette.

    Do email clients support APNG?

    Mostly not. APNG is a browser format. For email, GIF is still the safe choice.
