Download
MP4 isn't offered here — reliable MP4 encoding in the browser needs a very large additional download. WebM plays in almost all modern browsers and video players, and GIF works everywhere.

How resizing works
The original animation is wrapped inside a new composition sized to your target dimensions, with its own position and scale. This keeps the original artwork completely intact — nothing inside it is modified — while letting you place and scale it however you like within the new canvas.
Export formats
Lottie JSON and .lottie preserve full vector quality and stay editable. GIF and WebM are rendered, fixed-pixel exports — useful for sharing somewhere that doesn't support Lottie playback, such as email or a plain image slot.
Why does WebM export take real time?
GIF export renders each frame as fast as your browser can compute, but WebM export records the canvas as the animation actually plays, so it takes as long as the animation's real duration.
