Preview, check and convert Lottie animations. Everything runs in your browser, so your files stay on your device. And when you want to make your own, Mosso is the app for that.

Free Lottie animations
Loaders, confetti, animated text, icons and app moments. Pick a brand to recolour them, then download Lottie or dotLottie for free.
Make your own Lottie animations
Mosso is where you make them, not only open them. Start from a blank canvas or an animation from the library, add your words, logo and brand colours, and set how it moves with one click or with keyframes and easing. Then export Lottie, dotLottie, MP4 or GIF from the same project. You don't need to know animation.
Already have a Lottie? Open it in Mosso to change its colours and timing, then export it again.
Questions
What is a Lottie file?
A Lottie is an animation saved as data in a JSON file. Websites and apps play it with a small player, so it stays sharp at any size and is often much lighter than a video or GIF.
Are these tools really free?
Yes, with no sign-up and no watermark. They run on your own device, so they cost us very little to offer. They are part of Mosso, an app for making animations.
Are my files uploaded?
No. Every tool here runs in your browser. Your files are read on your device and never sent anywhere.
Which tool should I use?
To see what a file looks like and what is inside it, use the Lottie viewer. For email or chat, make a GIF. For social posts and video editors, make an MP4. For a smaller file on your site or app, use the dotLottie converter.
Can I make my own Lottie animations?
Yes, in Mosso. Start from a blank canvas or an animation from the library, add your words, logo and colours, animate it with one click or with keyframes and easing, then export Lottie, dotLottie, GIF or MP4. You can also open a Lottie you already have and change it there.
