Frequently Asked Questions
Can I merge vertically and horizontally?
Yes — stack images top-to-bottom or place them side-by-side, with a custom gap and background.
Do the images need the same size?
No — the merger normalizes widths (vertical) or heights (horizontal) automatically for a clean result.
How many images can I combine?
As many as you need — the browser handles the stack locally with no upload.
What is the best format for the merged file?
PNG for crisp screenshots and text; JPG for photos. Compress afterwards for the web.
How this tool works
Merging combines several images into one: side by side for comparisons, stacked for sequences, or in a grid for sets. The output keeps the pixel detail of the sources instead of screenshotting them together.
- Add your images, choose the layout (horizontal, vertical or grid) and the order. Narrower images are scaled or padded so edges line up cleanly instead of producing a ragged strip.
- The result exports at original resolution in JPG or PNG. Your files are combined on your device - none of them is uploaded.
Why one composed image travels better
Forums, emails and marketplaces frequently allow one attachment where you have five screenshots. A single merged image also tells a story in order: the receipt and its confirmation, the before and after, the steps of a tutorial - read top to bottom without clicking through.
Composing beats screenshotting because nothing is re-encoded twice: text stays sharp, colors stay exact, and the file size reflects the actual content rather than a lossy screen capture.
Pro tip: Match widths before merging if you can - consistent edges read as intentional design, while a ragged strip reads as a mistake.
