Merge Videos
Add two or more clips, put them in order and get one MP4 video. Phone videos, screen recordings and camera clips can be mixed.
- Add the videos
- Drag them into order and pick the size
- Download the merged MP4
Your files never leave your device
How the clips are joined
- Every clip is scaled into the same frame without stretching; black bars fill any difference in shape.
- Frame rate is unified to 30 fps and audio to 44.1 kHz stereo.
- Clips without sound get silence, so the sound stays in sync.
Choosing the size
- “Same as the first video” keeps the size of the first clip.
- Pick 9:16 for Reels, Shorts and TikTok, or 1:1 for square posts.
- Lower sizes (720p, 480p) process faster and make smaller files.
Speed
Joining re-encodes every clip on your device, which takes roughly as long as the total length of the videos on a fast computer. Keep the tab open until it finishes.
Frequently asked questions
Can I join videos of different formats?
Yes. MP4, MOV, WebM, MKV, AVI and more can be mixed; the result is MP4 (H.264 + AAC).
Are my videos uploaded?
No. They are joined on your device.
Why are there black bars?
Clips with a different shape than the output size are fitted inside it. Choose a size that matches most of your clips.
How do I change the order?
Drag the files in the list, or use the arrows, before merging.
Is there a size limit?
No fixed limit, but very long or 4K videos need a lot of memory and time. Try 720p for long projects.
Will the quality drop?
Clips are re-encoded at good quality; small differences are normal. Upscaling small clips cannot add detail.
