Place Four Images Side by Side Online — 100% Free

The four-image horizontal layout is a workhorse format with remarkably broad applicability across industries and use cases. For e-commerce, it's the product color variant display — red, blue, green, and black versions of the same item arranged in a clean row that lets shoppers compare at a glance without clicking through individual product pages. For education and tutorials, it's the step-by-step sequence — step 1 through step 4 laid out in chronological order so learners can follow the progression visually. For project management, it's the timeline strip — week 1, week 2, week 3, week 4 of a renovation or construction project showing progress over time. For creative portfolios, it's the style showcase — four variations on a theme displayed together to demonstrate range and versatility. For social media, it's the Story swipe-up preview — four related images in a 9:16 strip that invites viewers to engage with each frame. And for team pages, it's the headshot row — four team members presented in a uniform, professional format. Despite this utility, most image editing tools make the four-across layout unnecessarily complex: you have to calculate canvas dimensions, manually position each image, ensure equal spacing with pixel-level precision, and configure export settings — turning what should be a 30-second task into a frustrating multi-minute process. MergeFrame's 1×4 layout automation eliminates every manual step. You simply drop four images onto the canvas, and the tool instantly calculates equal cell widths based on your chosen export dimensions, proportionally fits each image without cropping or distortion, applies uniform spacing across all four cells simultaneously, and produces a perfectly aligned horizontal strip ready for download. The entire process from image selection to exported file takes under thirty seconds. For teams with repeatable workflows, standardizing the four-across format is straightforward: always use the same four image positions (slot 1 = primary, slot 2 = secondary, etc.), set spacing to a consistent 4px, and export at a fixed resolution — 1200px width for standard web display, 2400px for high-DPI Retina screens, or 2000×500px for product page hero strips. The grid reads naturally left-to-right in Western reading order, so position your most important or attention-grabbing image in the leftmost cell. For social media platforms, a 16:9 aspect ratio horizontal strip (1920×1080px) works well for Twitter, Facebook, and LinkedIn posts. For Instagram Stories, set custom dimensions to 1080×1920px with a 4×1 vertical layout instead. All processing is entirely client-side — your photos never leave your browser, ensuring complete privacy for unreleased product shots, personal photos, and sensitive visual materials.
