Why won't my MNG file display in the browser?

No browser supports it — browsers render PNG, JPEG, GIF, WebP, AVIF, SVG and BMP, and nothing else. The file downloads instead and needs an image editor.

The specification was complex, browsers never implemented it, and APNG offered most of the benefit with far less effort. WebP and video formats finished the job.

What should I convert MNG to?

Animated WebP for the web, MP4 for anything longer, or GIF if it must animate absolutely everywhere.

Host an MNG file and share it as a link

Put a Multiple-image Network Graphic online at its own address — the animated PNG that never caught on.

You can host:

Drop your MNG file here

Any other file works too — up to 25.0 MB, or 100.0 MB for a whole site

Free to use. Your MNG file is live at your-name.99helpers.site in about ten seconds.

What is a .mng file?

MNG was designed as PNG's animated counterpart, offering better colour and compression than GIF. Browsers never adopted it — the specification was complex — and APNG, WebP and video formats took the ground it was meant to occupy.

What people use MNG files for

Assets from projects that adopted MNG early

How to host a MNG file

1
Drop your MNG file in
Drag it onto the box at the top of this page, or click to choose it. Files up to 25 MB are supported, and nothing is uploaded until you publish.
2
Pick an address
Type a name and we'll tell you straight away whether it's free. That becomes the link: animation.99helpers.site
3
Publish and share
Create a free account — that step exists so the file is yours to update, replace or delete — and the link is live within seconds.

The same three steps work for any file — see how file hosting works on 99helpers.com.

What happens when someone opens the link

The file downloads. No browser ever shipped meaningful MNG support.

Why host a MNG file instead of emailing it?

Archived animations occasionally need sharing; converting to WebP or MP4 makes them viewable.

Worth knowing before you publish

Convert to animated WebP or MP4 for anything anyone needs to watch.
GIF is the fallback if you need something that animates absolutely anywhere.
ImageMagick converts MNG to other formats.
