FAQ
Can clips have different sizes?
Yes. The merger normalizes clips to a common MP4 profile before joining them.
How many clips can I merge?
There is no fixed small limit, but browser memory becomes the practical limit for large or many videos.
Is my video uploaded to a server?
No. This tool processes your files locally in your browser. BeYourTools does not upload, store, or send your media to a processing API.
