FAQ
Is VideoBuff free?
Yes, completely free. No account, no credit card required.
Which browsers are supported?
Desktop Google Chrome and Microsoft Edge. We use WebCodecs API, so Safari and Firefox have limited functionality.
Are my video files uploaded to a server?
No. All processing happens entirely in your browser. Your files never leave your device, ensuring complete privacy.
What video formats are supported?
MP4 (H.264/H.265) and any format your browser can play. Export supports H.264/H.265 up to 4K resolution.
Are my projects saved?
Yes. Projects auto-save to browser local storage. Asset files persist via OPFS (Origin Private File System), so you can close the page and resume later.
Can I use it with Claude?
Yes. We distribute a one-click .mcpb bundle for Claude Desktop / Claude Code. Once installed, Claude can operate VideoBuff for trimming, adding text, color grading, and more. It is an optional add-on — manual editing works exactly the same without it.
Can I use it on mobile?
Currently desktop only. Timeline editing and preview features are optimized for desktop environments.
