Upload a Lottie JSON or .lottie file and it checks for missing assets, font problems, renderer compatibility risks, expressions, excessive complexity, large embedded images, broken references, and structural issues.

It also shows the exact affected layer and JSON path instead of making you inspect the file manually.

I m exploring a new direction for LottieFyr: automatically finding and repairing common problems in Lottie files.

The idea:

• Upload a Lottie JSON or .lottie file

• Receive a free, downloadable report

• See compatibility, rendering, file-size, asset, and structural problems

• If an automatic fix is supported, receive a repaired file with a second verification report

• If it cannot be repaired safely, you are told clearly and are not charged

I originally built Lottiefyr to convert GIF and MP4 animations into Lottie files, but I kept thinking about another common problem: a lot of people already have clean SVG assets, but turning them into simple animated Lottie files is still annoying.

So I added a new SVG Lottie feature.

The idea is simple: upload a static SVG, choose an animation style, and export it as a Lottie file you can use in apps, websites, onboarding screens, buttons, loaders, or empty states.
