ABOUT THIS TOOL
Combine several clips into one video. Arrange them in order, choose MP4 or WebM, and preview the joined result before downloading.
How it works
Add your clips. Choose at least two videos. Add more clips if needed and check their order in the list.
Arrange and choose output. Reorder the clips, select MP4 or WebM, and choose Standard or High quality. The first clip determines the output dimensions.
Join and download. Join the clips, preview the transitions and sound, then download the combined video.
Formats and useful details
Input
Common video files such as MP4, MOV, WebM and MKV with browser-decodable tracks.
Output
MP4 or WebM.
Good to know
Clips are re-encoded into one continuous video. Different shapes are fitted inside the first clip’s dimensions with black bars where needed. Audio is joined in order, and clips without an audio track receive silence.
Processed on your device
Your selected files are processed on your device by the browser-based converter. Available formats and conversion speed depend on your browser, the file’s encoding, and your device. Large files may require more memory.
Frequently asked questions
Can I join videos with different dimensions?
Yes, when their media tracks can be decoded. The first clip sets the output dimensions. Other clips are fitted inside that frame, adding black bars when the aspect ratios differ.
Does joining preserve the original video quality?
The joiner re-encodes the clips, so it is not a lossless file append. High quality favors more detail and may produce a larger file. Preview the output before replacing your source clips.
Can I add transitions or trim each clip here?
This tool joins clips in sequence. It does not provide transition effects or individual clip trimming. Prepare those edits before adding your clips to the joiner.
