MP4 to WebM Converter – Fast, Secure & Browser-Friendly

Convert MP4 videos to WebM format instantly in your browser. Our lightweight tool provides high-quality, privacy-focused conversion with no uploads required.

Why Convert MP4 to WebM?

The WebM format is an open-source, royalty-free media format designed for the web. Unlike MP4, which may carry licensing restrictions, WebM is optimized for HTML5 video playback and delivers smaller file sizes without compromising on quality. If you're developing a website, creating a blog, or uploading videos for mobile-first users, WebM is the ideal format for seamless streaming and faster loading times.

  • Perfect for HTML5 video embedding
  • Faster load times and lower bandwidth usage
  • Supported by all major modern browsers

Private In-Browser Conversion

Your MP4 files never leave your device. All video processing takes place in your browser using modern JavaScript and WebAssembly technology. This ensures full privacy and fast performance, especially for users working with sensitive or proprietary media. No data is uploaded, stored, or tracked—ever.

  • 100% offline conversion
  • Keeps all video data secure
  • No file size limits or external uploads

Custom Conversion Settings

You can fine-tune your video output by selecting desired resolution, frame rate, or bitrate. Whether you need a compressed clip for social media or a high-definition video for professional purposes, our tool provides flexible options to match your workflow. The settings panel appears after you upload your MP4, so you stay in full control.

  • Choose video resolution (480p, 720p, 1080p, etc.)
  • Customize audio/video bitrate
  • Convert entire videos or selected segments
