Frequently asked questions
How do I combine several videos into one?▾
Add the clips, put them in the right order, then click Merge videos. When it finishes, download the single MP4 file.
Can I merge videos of different sizes?▾
Yes. Every clip is fitted into the output frame with black bars where needed, so nothing is cropped or stretched.
Is the sound kept?▾
Yes. The audio of each clip is kept and stays in sync; clips without sound get silence for their length.
Is there a limit?▾
You can merge up to 20 clips with a total length of up to 20 minutes. Merging needs a recent Chrome, Edge or Safari with video encoding support.
Is it free and private?▾
Yes. It is free with no watermark or sign-up, and the videos are processed on your device — nothing is uploaded.
