Merge Images
About the Merge Images
The Merge Images tool combines multiple image files into a single PDF page, arranging them together in a grid layout with a column count you control, rather than placing each image on its own separate page. This is the tool to reach for when you want several photos or screenshots to sit together, side by side, on shared pages — a contact sheet, a visual summary, or a compact reference document.
After uploading your images, you choose how many columns you want (from one to four), and the tool automatically calculates how many rows are needed based on your image count, then lays out a page sized to fit that full grid. Each image is scaled proportionally to fit its cell while preserving its original aspect ratio, so nothing gets stretched or distorted, and images are placed in the grid in the order you added them, filling left to right, top to bottom.
This is a natural fit for creating a visual overview document from a batch of related images — a set of product photos arranged into a simple catalog page, a collection of screenshots documenting a process step by step, a set of before-and-after photos placed side by side for comparison, or a contact sheet of scanned photographs for quick browsing before deciding which ones need further attention individually. Because everything lands on a shared page rather than one image per page, the resulting document is more compact and easier to browse at a glance than a long one-image-per-page file.
If you'd rather have each image on its own separate full page instead of grouped into a shared grid, the standard Image to PDF tool is the more direct fit for that use case. Merge Images is specifically built for the grid-layout scenario, and works especially well with a consistent column count that matches how you naturally want to group and compare your images — two columns for straightforward side-by-side comparisons, or three to four columns for a denser contact-sheet-style overview.
When choosing your column count, think about how the final grid will actually be viewed: two columns tends to work best when you want viewers to closely examine and compare each image individually, since larger cells mean more visible detail per image, while three or four columns suits a denser, at-a-glance overview where the goal is browsing many images quickly rather than studying any single one closely. If your images vary a lot in aspect ratio (some very wide, some very tall), be aware that the grid cells are all sized uniformly based on the page dimensions, so a mix of very different image shapes can leave noticeably more empty space around some images than others within their assigned cells.
Because layout and image placement happen entirely in your browser, this tool handles a reasonably large batch of images without needing to upload anything to an external image-processing service — useful when you're working with personal photos or scanned documents you'd rather keep off third-party servers while still producing a clean, organized combined document.
Step-by-Step Instructions
