The Image Joiner merges two or more pictures into one file, side by side, stacked, or in a grid. The canvas is sized for you, images of different dimensions can be matched on height or width, and a gap in any colour separates them. Order follows the queue, which you can drag to rearrange.
Putting two pictures in one file is how before-and-after comparisons, step-by-step screenshots and simple photo strips get made. Doing it in an image editor means creating a canvas, working out the arithmetic and aligning by eye.
Here you drop the images in, choose horizontal or vertical, and the canvas is sized for you. Images of different sizes can be matched on height, matched on width, or left alone and aligned; a gap in any colour can be set between them. The order is whatever order you added them in, and they can be dragged in the queue to change it.
Side by side for comparisons, stacked for sequences, grid when there are more than a handful.
Match on height, match on width, or leave images alone and choose an alignment — the canvas fits whichever is largest.
A few pixels of gap in white or black reads far better than images touching edge to edge.
Drag the thumbnails to change which image goes where, without removing and re-adding files.
Nothing is drawn onto the output and nothing is uploaded — the merge happens on a canvas in your browser.
Drop them all in at once, or add them one at a time. They appear in a queue.
Horizontal puts them side by side; vertical stacks them; grid arranges them in rows.
A few pixels of gap in white or black reads much better than images touching.
One file containing all of them, at full resolution.
Choose how to reconcile them: match heights for a horizontal join, match widths for a vertical one, or leave them at their own sizes and pick an alignment. The canvas is sized to whichever is largest.
As many as you like. Beyond about six, the grid layout usually reads better than one long strip.
Yes — drag the thumbnails in the queue. The join follows the queue order left to right, or top to bottom for a vertical stack.
No. Nothing is added to the output, and nothing is uploaded — the merge happens on a canvas in your browser.
