Photo arrangement sits at the intersection of curation and composition. Before you arrange, you curate — selecting which photos belong together and excluding those that distract or dilute. Then you compose — determining the order, spacing, and visual relationships that transform a collection of individual images into a single meaningful visual. This two-step process is where most tools fail: they either lack the curation interface (you're stuck arranging in a file manager) or lack the composition controls (you get one layout with no customization). MergeFrame handles both elegantly. Curation happens naturally through the drag-and-drop interface — you see all your photos in the grid simultaneously, making it instantly clear which combinations work and which don't. Swap photos between cells by dragging; remove a photo by dragging a replacement into its cell; add more photos by dropping them into empty cells. The arrangement stage — composition — is where MergeFrame's controls shine: global cell spacing from 0 to 20 pixels adjusts the visual density of the entire arrangement with one slider, optional cell borders define individual photo boundaries, grid layout switching lets you change from 2×2 to 2×3 mid-arrangement without losing photo placement, and export resolution control matches your output to its destination. Effective arrangement strategies for common scenarios: Chronological arrangement — order photos from earliest to latest (left-to-right, top-to-bottom). Works for event recaps, project timelines, growth journeys. Contrast arrangement — place contrasting images adjacent to each other to emphasize differences. Before/after pairs, light/dark variations, wide/close-up shots. Color-flow arrangement — arrange by dominant color, creating a smooth transition across the grid. Warm → cool, or follow the color wheel. Hierarchy arrangement — the most important image in the top-left (first-read position), supporting images following in descending importance. Narrative arrangement — photos ordered to tell a beginning-middle-end story. The viewer's eye follows the plot across the grid. The arrangement tool's real-time preview makes experimentation cost-free — you can try five different arrangements in under a minute, comparing each version before committing to an export. All processing is local (Canvas API), all exports are watermark-free PNG at up to 4000px. Free tier: all grids, full resolution, unlimited exports.
