How to merge videos
- Drop two or more video clips onto the box, or tap to choose them. You can add more at any time.
- Put them in order with the ↑ and ↓ arrows, and remove any you do not want.
- Choose the output size. "Same as first clip" keeps your original size; pick 9:16 for TikTok and Reels or 16:9 for YouTube.
- If the clips have different shapes, choose black bars (nothing is cut off) or fill and crop.
- Press Merge videos, wait while the clips play through, then watch the result and download it.
Join clips without uploading them
Joining phone clips into one video is one of the most common editing jobs: a holiday montage, several takes of a tutorial, parts of a presentation, a wedding speech filmed in pieces or short clips for a product reel. Most online joiners upload your files to a server and add a watermark. Here the clips are played one after another inside your browser and recorded into a single new file, with their sound, so nothing leaves your device and there is no watermark.
Because the result is recorded as it plays, merging takes about as long as the total running time; keep the tab visible while it works. Clips with different resolutions or orientations are scaled to the output size. Chrome, Edge and Safari can save MP4; Firefox saves WebM. For best quality, start from the original files rather than copies sent through messaging apps.
Can I merge MP4 and MOV files together?
Yes, as long as your browser can play each file. iPhone HEVC .mov files play in Safari; in other browsers, export them as "Most Compatible" first.
Is there a limit on the number of clips?
No fixed limit. Very long results depend on your device's memory.
Will the sound be kept?
Yes, each clip's audio is included unless you tick Remove audio.
Is my video uploaded?
No. Everything happens in your browser.
