Convert MNG to GIF

MNG to GIF converts Multiple-image Network Graphics (.mng) animations — PNG’s little-known animated sibling — into GIFs that play everywhere. It extracts each embedded PNG image, applies its placement (DEFI) and frame timing (FRAM, MHDR ticks) and rebuilds the animation. PNG-based MNG-LC and MNG-VLC files are supported; JNG (JPEG-based) images are not.

What happened to MNG?

MNG was designed by the PNG Development Group as PNG’s answer to animated GIF, and finalised in 2001. It is powerful — full alpha, 24-bit colour, layered composition — but complex, and browser support was short-lived: Mozilla removed it in 2003. Today APNG has taken its place on the web, so MNG files mostly survive in old game assets, emulator screenshots and archives.

Converting to GIF makes those animations viewable again. For a modern format with full alpha instead, convert the resulting GIF to APNG with GIF to APNG, or to video with GIF to MP4.

If your MNG won’t open

Some MNG files store frames as JNG (JPEG Network Graphics) or as delta-PNG patches; those variants aren’t supported. If you have the original frames as separate PNGs, Images to GIF can rebuild the animation. Other legacy animations — such as Windows cursors — go through ANI to GIF.

Features

  • Plays the unplayable

    No mainstream browser has shown MNG for two decades.

  • Timing preserved

    Reads ticks-per-second and interframe delays.

  • Positions respected

    Partial-frame images are placed with their DEFI offsets.

  • Transparency kept

    PNG alpha becomes GIF transparency.

MNG to GIF FAQ

How do I open an MNG file?

Modern browsers and most image viewers can’t display MNG. Convert it to GIF here, and it will play in any browser or app.

Which MNG files are supported?

MNG-LC and MNG-VLC files built from embedded PNG images — the most common kind. JNG-based and delta-PNG files are not supported.

Will transparency be kept?

Yes, as GIF transparency. GIF only has on/off transparency, so partially transparent pixels become fully solid or fully clear.

Are my files uploaded to a server?

No. GifRush processes everything locally in your browser using JavaScript, Canvas, Web Workers and WebCodecs. Your files never leave your device, and closing the tab discards them.
