WebM to MKV helps when you want a robust container for storage, library management, or broad desktop player compatibility.
If you need maximum device compatibility, use WebM to MP4. If you want a small web-first result, WebM is already optimized for that role.
Best for
- Local archiving and collections
- Desktop playback workflows (VLC-friendly)
- Container flexibility for your media library
Why use Client Tools?
- Privacy-First & Secure: All processing happens directly in your browser. We never upload your files to any server.
- Corporate Grade Security: Ideal for handling sensitive documents, contracts, and NDA-protected images. Since data never leaves your device, it is impossible for third parties to intercept it.
- No Limits: Convert as many files as you want, of any size (limited only by your device's RAM).
- Fast & Offline Capable: Works instantly without waiting for network uploads.
How it works
Unlike other converters that require you to upload your files to a cloud server (which creates a privacy risk), Client Tools uses advanced WebAssembly technology to run professional image processing software directly inside your web browser.
