Transparency Support

When to Use WebM Format
WebM excels in specific scenarios where transparency and web optimization matter:
Video Overlays
Layer animations on top of other videos or content. Transparent WebM works like alpha-channel video in video editors.
Web Background Videos
Hero sections, landing pages, and full-page backgrounds. WebM's small file size ensures fast loading on all connections.
HTML5 Video Elements
Use in <video> tags with transparency. Perfect for UI animations, product demos, and interactive web experiences.
Progressive Web Apps
PWAs and modern web apps benefit from WebM's efficiency. Smaller downloads, faster playback, native browser support.
Presentation Backgrounds
Modern browsers support WebM in presentations. Use transparent animations behind slides for dynamic effects.
Animated Stickers & GIFs
Alternative to animated GIF with better quality and smaller size. Perfect for messaging apps and social platforms that support WebM.
WebM Optimization Tips
Get the most out of WebM format for your Lottie animations:
Enable transparency when needed
Only use alpha channel if you need it. Opaque videos compress better. Set a solid background color if transparency isn't required.
Balance quality and file size
WebM quality slider: 60-70 for web use, 80-90 for archival. Higher quality means larger files. Test what works for your use case.
Provide MP4 fallback for Safari
Safari on older devices doesn't support WebM. Use <video> tag with both WebM and MP4 sources for maximum compatibility.
Optimize resolution for web
720p-1080p is ideal for most web use. 4K WebM files can be large despite good compression. Match resolution to your display needs.

Frequently Asked Questions
Everything you need to know about Lottie animations and our tools.
What is WebM and why use it?
WebM is an open-source video format designed for the web. It offers excellent compression with VP9 codec, supports alpha channel (transparency), and is widely supported by modern browsers. It's ideal for embedding animations with transparent backgrounds.
Does WebM support transparency?
Yes! WebM with VP9 codec supports alpha channel, allowing you to export animations with transparent backgrounds. Simply check the "Transparent Background" option before converting.
How does WebM compare to MP4?
WebM offers better compression than MP4 at similar quality levels and supports transparency, which MP4 doesn't. However, MP4 has broader support on older devices. WebM is ideal for modern web applications prioritizing file size and transparency.
What quality settings should I use?
Medium quality (default) works well for most animations. Use High or Very High for detailed animations with gradients or fine elements. Low quality is suitable for simple animations where file size is critical.
Can I convert large Lottie files?
Yes, but conversion time depends on animation complexity, duration, and selected quality. Longer animations or high FPS settings will take more time. All processing happens in your browser for privacy and security.
