Is this video merger really free with no watermark?

Yes, 100% free with no watermarks, no signup, and no file size restrictions beyond your browser's memory. All processing happens locally in your browser.

How many videos can I merge at once?

You can merge up to 10 video clips in a single operation. Each clip can be up to 500MB in size.

Why does merging take a long time?

Merging happens in real time in your browser — the processing time roughly equals the total duration of all your clips combined. For a 5-minute total video, expect about 5 minutes of processing. Keep the tab open and active.

Can I change the order of the clips?

Yes! You can drag and drop clips to reorder them, or use the up/down arrow buttons. The clips will be merged in the order shown in the list.

Will the audio from all clips be included?

Yes, audio from all clips is included by default. You can check "Remove Audio" in the settings to produce a silent video, which also results in a smaller file size.

Are my videos uploaded to any server?

No. All video processing happens entirely within your browser using the Canvas API and MediaRecorder API. Your videos never leave your device.

What is the fade transition option?

The fade transition adds a smooth fade-out/fade-in effect between each clip, making the video feel more polished. The "No Transition" option cuts directly from one clip to the next.

Can I use this on mobile?

The tool works on mobile browsers, but performance is better on desktop due to the processing power required. Chrome on Android works best for mobile use.

What output resolution should I choose?

720p is a good balance of quality and file size for most uses. Choose "Original" to keep the maximum quality, or 480p for smaller output files. If your clips have different resolutions, the tool scales them to match.

How Video Merging Works

The tool uses your browser's built-in Canvas API and MediaRecorder API to draw each video frame-by-frame and record them into a single output file. Audio is mixed using the Web Audio API. This means no server is involved — everything runs locally and privately.

Who Is This For?

Content creators combining Instagram Reels or YouTube Shorts clips, students joining lecture recordings, video editors needing quick merges without desktop software, and anyone who wants to join multiple clips into one file without installing anything.

Supported Formats

Input: MP4, WebM, MOV, AVI. Output format depends on your browser — Chrome and Firefox produce WebM, while Safari may produce MP4. All output formats play natively in browsers and can be uploaded to any social media platform.

Tips for Best Results

Use clips with the same resolution and frame rate for the smoothest merge.
Keep this tab active while merging — the process runs in real time.
For large files (over 100MB each), use the 720p output resolution option to reduce processing time.
