Files are handled as local browser objects. BeYourTools does not upload video or audio contents, does not store filenames, and does not send media to third-party processing APIs.

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.
