Merge Images Online — Free, No Upload Required
Stitching photos together — before/after shots, a strip of screenshots, a set of receipts — usually means opening a design app just to place two files side by side. This tool skips that: drop in multiple images, arrange them horizontally, vertically, or in a grid, and export one combined file, all inside the browser tab.
Why local processing matters here: merging often involves photos you’re about to send somewhere — a landlord, an insurance claim, a support ticket. Routing them through a server just to glue them together is an unnecessary hop for images that may contain your address, your face, or your account details.
How to use it
- Add your images in the order you want them to appear (drag to reorder afterward).
- Choose a layout: horizontal strip, vertical stack, or grid.
- Set the gap between images and background color, if any.
- Preview the combined canvas.
- Export as PNG or JPEG.
Common situations this solves
- Combining a “before” and “after” photo into one image for a review or portfolio
- Stacking multiple scanned pages of a handwritten note into one shareable file
- Building a quick side-by-side product comparison shot
- Assembling screenshots of a long conversation or thread into one image
- Creating a simple contact-sheet-style preview of a shoot
FAQ
Does merging reduce image quality? No — the tool places your originals at full resolution on the canvas; any quality loss only happens if you also compress the final export.
Can I merge images of different sizes? Yes, the layout tool auto-aligns them; you can choose whether smaller images get padded or scaled to match.
What if I need a circular arrangement instead of a grid? This tool is built for strip/grid layouts. For freeform collage-style layouts, the Contact sheet / collage tool gives you more control over spacing and captions.
Will this add a watermark? No, nothing is added unless you use the separate Image watermark tool afterward.
Can I merge more than 10 images at once? Yes, there’s no hard cap — very large grids may just take a moment longer to render since it’s all happening on your device rather than a server queue.
