Animated PNG Maker
Animated PNG output:
Online Animated PNG (APNG) maker
This tool will assemble individual image files into an animated PNG file. It gives you options to change frame order using drag and drop, set frame disposal (whether or not to keep the previous frame in the background), set loop count, or skip the first frame. If you are making an animation with transparent areas, it's possible to use the first frame as a background image for the rest of the frames.
You can also use it to edit existing APNG (change frame order, animation speed, disposal method), merge multiple APNG files, add or remove frames from animation or convert other types of animated images to APNG. It can import APNG, WebP, GIF, FLIF, and MNG animations, as well as archives of images (ZIP, RAR, 7z).
Animated PNG files work similarly to animated GIFs but can contain more colors, partial (alpha) transparency, and other features for much greater image quality.
You can find an up to date table for APNG support in different browsers at https://caniuse.com/#search=apng.
