WebM Compressor – Online & Free

WebM is an open, royalty-free media format created by Google for the web, pairing efficient VP8, VP9, or AV1 video with Vorbis or Opus audio to stream quickly while keeping quality high. It’s the format behind much of today’s HTML5 and online video. Although WebM is already efficient, high-resolution or lengthy clips can still grow larger than ideal for uploads, storage, or sharing.

When a WebM file is too big to handle, the Movavi compressor lets you compress WebM online without installing anything. It’s free, the whole process happens in your current browser tab, and it takes three steps: upload your video, choose your settings, and download. You can reduce WebM file size for websites, email, cloud storage, or social uploads. This free WebM compressor keeps the picture sharp while cutting the size, and it handles long or high-resolution footage with ease. By letting you adjust bitrate, Movavi acts as a handy WebM size reducer online that shrinks a WebM file without throwing away the detail that keeps your video looking great.
