The phrase 'arrange photos in a grid' describes an action everyone has attempted — and most have struggled with. Manually positioning images in PowerPoint, wrestling with CSS grid layouts, or fighting alignment tools in Photoshop is frustratingly slow when all you want is a clean, evenly-spaced arrangement. MergeFrame makes photo arrangement genuinely effortless. The tool provides five preset grid layouts that cover every common arrangement: 1×2 for horizontal pairs ideal for comparisons, 1×3 for trios that work for step-by-step sequences and color variants, 2×2 for the classic square arrangement that dominates Instagram and portfolio displays, 2×3 for six-image collections that fit product showcases and tutorial steps, and 3×3 for full nine-image arrangements that create comprehensive visual catalogs. The arrangement process is built for speed: choose your layout, drag your photos into the cells, adjust spacing to taste, and download. You can rearrange photos at any time by dragging them to different cells — the grid preview updates in real time so you can experiment with composition freely before committing to an export. Each photo is proportionally fitted to its cell regardless of original dimensions, so a phone snapshot and a DSLR image can coexist in the same grid without one dominating or getting cropped. The arrangement tool's spacing slider (0–20px) is the key to visual polish: 0px creates a seamless mosaic where images touch — ideal for art compositions and mood boards. 4–8px provides clean professional separation that works for documentation, product listings, and formal presentations. 12–20px creates gallery-style arrangements with distinct visual framing around each image — excellent for portfolio displays and print-ready keepsakes. Optional cell borders add definition when images share similar backgrounds. All processing happens locally in your browser via Canvas API, meaning your photos never upload to any server during arrangement. This privacy guarantee is critical for professional use cases where photos contain unreleased products, confidential information, or personal moments. The output is a single lossless PNG at any resolution up to 4000px — ready to embed in websites, attach to emails, upload to social media, or print at high quality.
