With MP4toGif.com you are able to convert video (MP4,OGV) and images (JPEG,PNG) to simple WebM and Gif animations. MP4toGif based complety on JavaScript and HTML5 technology and runs in your webbrowser. So there is no need to upload your files and give it in the hands of a second person.. or company.

MP4toGif was testes on Firefox, Chrome and Edge. Because of the native WebP-support in the canvas-implementation of the chrome-browser, the rendering is very fast with chrome. Firefox uses webworkers to enable a stable and fast-enough rendering process.

The duration of a WebM-animation is restricted to 20 seconds or 50 frames (if the animation is created from image-files). But it is enough to replace a classic Gif-animation and have better color and image quality and also a smaller file-size.

A filter for automatic black ∧ white conversion was integrated, so an BW-animation from a colored video or images can be created directly without processing the footage-files with a seperate programm.

I don't like watermarks on gifs. But i want more visiters so the Google adds would bring in some money. I would like to refactor the gif export to use Webworkers to enable longer durations and better performance. Also i would like to import exsting gif-animation or capture a videostream via WebRTC. But(!) this needs much of time and if i will spend this time to improve mp4togif.com i wouldn't have time to cook.. so please donate that i can order pizza and spends the saved time to this project :-)
