Mosaic: Video Collage Maker

Put your photos and videos in the same frame and watch them play together. Pick 2 to 4 photos or clips, choose a layout, and Mosaic builds one frame where every video plays at once, looping together so the whole collage stays in step. Drag the dividers to resize any cell. Pan and pinch to reframe what sits inside it. TRIM AND MIX Every clip gets its own filmstrip. Drag the handles to land on the exact moment you want, with the playhead moving live as you go. Set the volume per clip or mute it, and the clips you leave unmuted play their audio together as one mixed track. LAYOUTS 18 templates for 2, 3, and 4 items, in square, 4:5, 3:4, 9:16, and 16:9. Adjust the spacing between cells, round the corners, and set the backdrop color to suit wherever it is going. EXPORT Save as a video at 720p, 1080p, or 4K, or as a still image. Finished collages land in your photo library and open straight into the share sheet. YOUR COLLAGES Saved work stays editable. Come back to re-trim a clip, swap a photo, rename a collage, or duplicate one to try the same media in a different layout. Mosaic runs entirely on your device. Your photos and videos are never uploaded.
