MAKE COLLAGES • Choose from 120 layouts for collages with 2–9 photos. • Explore classic grids, flowing curves, hearts, petals, honeycomb patterns, clouds, concentric rings and comic-style panels. • Choose a layout first, then add your photos—or start with photos. • Browse and preview layouts while keeping your collage in view. • Remix the arrangement and adjust spacing, background colors and rounded corners in supported layouts. • Drag and pinch to reposition and zoom your photos with a live preview. ADD YOUR OWN TEXT • Add text to ready-made and freeform photo collages. • Choose from 8 font styles and preset text colors. • Move, resize and rotate text directly on the canvas. • Save your text with your project and include it in the exported image. CREATE FREEFORM • Draw across a photo to cut it into custom shapes. • Sketch your own collage layout, then fill each region with a photo. • Keep drawing to create more pieces or photo spaces. • Reposition, replace and swap photos within your layout. • Export cut pieces as transparent PNGs or on a JPEG canvas. CREATE LONG IMAGES • Combine 2–20 photos or screenshots into one vertical image. • Reorder images and crop unwanted content from the top and bottom. • Find possible screenshot overlaps, review suggestions and fine-tune each join with a live preview. • Preview and trim repeated headers and footers. • Cover private details with opaque black or white rectangles before exporting. • Export as JPEG or PNG, save to Photos, or share. • Save long-image projects and continue editing later. MAKE VIDEO COLLAGES • Combine two videos in a top-and-bottom split screen. • Preview both clips together and adjust each clip’s framing independently. • Choose a 9:16 or 4:5 canvas. • Use audio from the top clip, the bottom clip, or neither. • Export a single MP4 with the duration of the shorter clip. FINISH AND SHARE • Preview your result before exporting. • Save photo and video projects and continue later. • Organize saved projects with swipe-to-delete and multi-select deletion. • Save finished photos and videos to Photos or share from your iPhone.
