Frequently asked questions

What is the Advanced Optimizer?

Granular control over animation compression. Adjust bezier curves, keyframes, images, and JSON properties individually. Works on any animation.

How is it different from Optimized dotLottie?

Optimized dotLottie applies fixed rules automatically. Advanced Optimizer lets you control each setting manually. Use both: Optimized dotLottie for baseline, Advanced Optimizer to push further.

What does converting to dotLottie do?

Gzips your multiple Lottie animations and bundles assets, themes, and states into one file. Up to 80% smaller than Lottie JSON.

Will this change how my animation looks?

Not with the default settings. The only risk is pushing the tolerance sliders too high. Always preview before shipping.

What is the full optimization workflow?

Edit in Lottie Creator. Export as dotLottie. Apply Advanced Optimizer. Each layer stacks.

Does it work with both Lottie JSON and dotLottie?

Yes. It works on both Lottie JSON and dotLottie.
