GIF to APNG converter
Convert animated GIF to animated PNG (APNG) with one click.
Keep in mind, while APNG supports much larger number of colors and alpha channel, simply converting GIF to APNG won't give you quality improvements over the original GIF (but it may reduce file size in some cases). You'll need to recreate the animation from source images or video to take advantage of all the benefits of APNG.
