Merge Video

About this tool

This free video merger joins several clips into a single video. Add your files, drag them into the order you want with the arrows, pick MP4 or WebM, and the tool stitches them together — right in your browser.

Every clip is matched to a common size so the joined video plays smoothly, and clips without sound get a silent track so the audio stays in sync. Nothing is ever uploaded — the whole thing runs on your device.

Features

• Combine two or more clips into one video
• Reorder clips with up/down arrows before merging
• Output as MP4 (most compatible) or WebM
• Handles clips of different sizes — each is scaled and padded to fit
• Keeps audio in sync, even when some clips are silent
• 100% in-browser — your videos are never uploaded

Common uses

• Stitch together phone clips into one video
• Combine an intro, main clip and outro
• Join screen recordings or gameplay segments
• Put several short clips into a single file to share

A note on speed

Merging re-encodes your video in the browser, so large or long clips take time and memory. For best results, use clips that share the same format and resolution. The engine downloads once (about 30 MB) the first time you use it.

How to use it

• Add your videos — click the upload area or drag several files in
• Set the order — use the arrows to move clips up or down
• Pick a format — MP4 or WebM
• Merge videos — wait for it to finish, then play and download
