Mosaic Photo & Video Collage

Mosaic is a versatile collage creation app that allows you to arrange photos, videos, Live Photos, and empty tiles using one of 345 built-in layouts or your own custom layouts created in the collage editor. Tiles are defined by adjustable width and height factors, can contain media or remain empty, and support customizable metadata including titles, opacity, border width and color, and corner radius. The editor provides tools for adding, removing, replacing, cropping, rotating, and editing media, as well as managing tiles and creating cropped image variants. Mosaic automatically generates icons for custom layouts and includes a unique "Jumble" mode that randomly positions tiles for freeform arrangements that can be manually adjusted. Layouts also define collage dimensions, background colors or patterns, and tile spacing, while randomization tools can automatically vary tile sizes, opacity, borders, colors, and corner curvature to create distinctive visual effects.
