Frequently Asked Questions

❓ Are my video clips uploaded to any remote server or cloud service?

No. Your video files are processed entirely locally inside your web browser using HTML5 Canvas, the Web Audio API, and client-side MediaRecorder APIs. Your video data never leaves your device and is never transmitted over the internet.

❓ Are there any file size or duration limits?

There are zero artificial limits, usage tiers, or watermarks. Since all processing takes place within your computer's local RAM and browser execution engine, you can combine as many clips as your device's memory can handle.

❓ What video formats can I combine?

You can import any browser-playable video format including MP4, WebM, MOV, and MKV. The output video is encoded into a universally compatible MP4 or high-efficiency WebM file.

❓ Can I combine videos with different aspect ratios or resolutions?

Yes! Our tool supports intelligent Fit modes. You can choose 'Fit with Letterbox' to preserve each clip's original aspect ratio with clean black borders, 'Fill & Crop' to fill the frame completely, or 'Stretch'.

❓ Does this tool work completely offline?

Yes. Once the page is loaded, the entire video merging engine runs completely offline. You can disconnect from the internet and merge private videos with total security.
