Why do Lottie .JSON files render blurry in Chrome but crisp in Firefox in Webflow?

The issue of Lottie .JSON files appearing blurry in Chrome but crisp in Firefox in Webflow can be attributed to a difference in rendering engines and the way each browser handles the animation.

Lottie is a library that renders animations using vector graphics, allowing for smooth and scalable animations across different devices and platforms. However, the rendering of vector graphics can vary between browsers.

Chrome uses the Blink rendering engine, while Firefox uses Gecko. These rendering engines may interpret vector graphics differently, resulting in variations in the visual quality of Lottie animations.

One possible reason for the blurriness in Chrome is the way it handles anti-aliasing, which is the smoothing of jagged lines or edges. Anti-aliasing in Chrome may not be as efficient or optimized for Lottie animations, leading to a loss of crispness.

To overcome this issue, you can try a few potential solutions:

• Export Lottie files with higher pixel densities: When exporting your animations from the design software, try exporting them at higher resolutions or pixel densities, such as 2x or 3x. This will provide more detail and may help reduce blurriness.
• Ensure your Lottie animation dimensions match the container size: Make sure that the dimensions of the Lottie animation match the size of the container it is placed in. If the animation is scaled up or down significantly, it can result in blurry rendering.
• Experiment with different Lottie export options: Some design applications allow you to adjust various export settings for Lottie animations. Try experimenting with different options like frame rate, compression, and export sizes to see if it improves the rendering quality across different browsers.
• Use Webflow interactions instead of Lottie: Instead of relying solely on Lottie animations, you can recreate certain animations using Webflow's built-in interactions capabilities. By using CSS animations or Webflow interactions, you can achieve similar effects without relying on external libraries like Lottie.
• Test on different versions of Chrome: Browser updates can sometimes affect rendering quality. Try testing the Lottie animations on different versions of Chrome to see if the issue persists. If it appears to be related to a specific version, you can report the bug to the Chrome development team.

In conclusion, the variation in Lottie animation rendering quality between Chrome and Firefox in Webflow can be influenced by the different rendering engines used by each browser. By experimenting with export settings, matching dimensions, and considering alternative animation methods, you may be able to mitigate or overcome the blurriness issue.
