Runs entirely in your browser - no upload, no sign-up.
Check the layout, spacing, and crop before exporting.
Choose how your clips share the finished frame.
Every clip starts together. The shortest selected clip sets the final duration, so the collage ends without freezing or looping a source.
Press Ctrl+Enter or Command+Enter to export.
Your clips and finished MP4 stay in this browser tab. Nothing is uploaded.
A video collage maker combines several clips into one frame so they play at the same time. Add two videos for a side-by-side or stacked split, or four for a 2 x 2 grid. Choose spacing, background, size, and audio, then export an MP4 entirely in your browser.
Choose two clips for a split layout or four clips for a 2 x 2 video grid.
Arrange two videos side by side or stacked, or place four videos into an equal grid.
Choose the output resolution, gap size, background color, and which clip supplies audio.
Preview the composition, export it locally, then download the finished MP4.
This editor creates a simultaneous composition, not a sequence. Each source begins at the first frame and occupies an equal cell. Mixed aspect ratios are fitted inside their cells without stretching, and the chosen background fills any unused space.
The local WebAssembly video engine loads only when you export. It scales and composites every frame into an H.264 MP4, keeps one optional source audio track, and adds no watermark. Your files are never sent to a project server.
No. The browser opens each clip as a local file and passes it to a WebAssembly video engine running in the current tab. The engine code downloads when first needed, but your source videos and completed MP4 are not uploaded to the server.
Yes. You can combine two or four videos, choose a layout and output settings, then export and download an MP4 without an account, subscription, or watermark. Processing capacity depends on your browser, available memory, clip length, and resolution.
The editor supports two videos in side-by-side or stacked layouts and four videos in a 2 x 2 grid. This focused limit keeps the controls readable on phones and reduces the memory needed to decode several video streams at once.
All selected clips start together, and the finished collage ends when the shortest clip ends. The tool does not loop short clips or freeze their final frames. Trim longer videos first if you need a particular section to fit the shared duration.
Yes. Choose the Side by side layout and add two clips. Each video receives half of the landscape frame, with an adjustable gap between them. Portrait or square sources are fitted inside their cells without changing their proportions.
You can keep the audio track from any selected clip or export the collage muted. Only one source is used because mixing several unrelated tracks often creates clipping and echo. Prepare a mixed soundtrack separately if you need audio from multiple sources.
The browser must decode several videos at once, resize every frame, place the frames on a new canvas, and encode a fresh H.264 file. Four 1080p clips require much more memory and processing than two short 720p clips, especially on mobile devices.
