Why use Aback Video for this
Much smaller files
The same animation as video is commonly 80 to 95 percent smaller than the GIF.
Accepted by social apps
Instagram and many other apps reject GIF uploads but accept MP4.
Transparency handled
Video has no transparency, so transparent pixels are filled with the colour you choose instead of turning black.

Frequently asked questions
Will the WebM loop like a GIF?
A web page can loop it with the loop, autoplay and muted attributes on the video element. You can also repeat the animation inside the file a set number of times.
What happens to transparency?
Transparent parts of the GIF are filled with the background colour you choose, white by default.
Why is the MP4 so much smaller?
Video codecs store only what changes between frames and compress each frame far better than GIF can. A 10 MB GIF often becomes a 500 KB MP4.
Will the MP4 loop?
Video files play once by default. Many apps loop short videos automatically. You can also repeat the animation inside the file with Repeat the animation.
What happens to transparent parts?
MP4 cannot be transparent, so they are filled with the Background colour. White suits most GIFs; pick a colour that matches where you will post it.
Why are the dimensions slightly different?
H.264 requires even widths and heights, so an odd-sized GIF is rounded by one pixel.
Is my GIF uploaded?
No. FFmpeg converts it inside your browser.
Does it work on mobile?
Yes. GIF conversion is light and quick in mobile browsers.
