Merge Videos Online – Free, Private, No Upload
This free video merger lets you combine multiple video clips into one file right in your browser. Add your videos, trim the start and end of each clip, put them in the order you want, choose an output size, and download the merged result as MP4 or WebM — no signup, no upload, no watermark.
What Is a Video Merger?
A video merger joins two or more video clips into a single continuous video. It is useful for stitching together phone recordings, combining screen captures, joining highlights into one reel, or putting intro, main content, and outro clips into one file for sharing.
How to Use This Video Merger?
Add your videos by clicking the Add videos area or dragging files in. Click Trim on any clip to cut its start or end by dragging the handles on the timeline or typing exact times. Reorder clips with the arrow buttons, then choose the output size, fit, background color, audio, and frame rate. Click Merge Videos, wait while the clips are combined, then preview and download the result.

Frequently Asked Questions
Is this video merger free?
Yes, it is completely free with no hidden charges, no watermarks, and no daily limit.
Are my videos uploaded anywhere?
No. All merging happens locally in your browser. Your videos are never sent to a server and are discarded when you refresh or leave the page.
Why does merging take as long as the video itself?
To keep everything private and on your device, the tool plays each clip in order and records the result in real time. A 5-minute combined video takes about 5 minutes to merge. Keep the tab open and visible until it finishes.
What output format do I get?
You get MP4 when your browser supports recording it, otherwise WebM. Both play in modern browsers and most video players.
Can I merge videos with different sizes?
Yes. Choose an output size and either Contain, which keeps the whole clip visible with background bars, or Cover, which fills the frame and crops the edges.
Can I trim or cut my clips before merging?
Yes. Click Trim on any clip, then drag the start and end handles on the timeline, use Set start here and Set end here while previewing, or type exact times. Only the part you select is included in the merged video.
Which video formats can I add?
Any video format your browser can play, such as MP4, WebM, and MOV in most browsers. If a file will not load, your browser does not support its codec.
