Why merge WebM files?

WebM is a popular video format on the web, especially for browser-based recording tools and lightweight exports. Merging WebM files lets you turn a series of short captures into one continuous video, which is much easier to share, archive, or upload to hosting platforms.

From WebM to MP4 for compatibility

While WebM is efficient and browser-friendly, MP4 is more widely supported across devices and apps. This tool merges your WebM clips and converts them into a single MP4 so you can open the video nearly anywhere.
