Multiple-image Network Graphics — a PNG-based animation format proposed in the late 1990s. Largely superseded by APNG and animated WebP, but still useful for archives and niche viewers.

What software opens MNG?

XnView, IrfanView, GIMP, and ffplay open MNG. Most modern browsers do not — for the web, prefer APNG or animated WebP.

Are my files uploaded?

No. The container is assembled in your browser; nothing leaves the device.

Frequently asked questions

Will browsers play this MNG?

No — modern browsers dropped MNG support long ago. Use APNG or animated WebP for the web.

Why is the file so large?

MNG-VLC (Very Low Complexity) embeds full PNGs per frame without inter-frame delta. Smaller per-frame inputs help.
