Long image stitcher
Stack several images into one long image.
Long image stitcher combines multiple images into a single long image, either stacked top-to-bottom or placed side-by-side, scaling them to a common width or height so the edges line up.

How we verify Long image stitcher
How to confirm the images stitched together in the right order and alignment.
Order follows the list, which you can rearrange
Images are stitched in the order they appear in the list — use the up/down arrows to reorder them before stitching if they weren't added in the right sequence.
Images are scaled to a common width or height
For vertical stitching, every image is scaled to match the narrowest image's width; for horizontal, they're scaled to the shortest image's height — this can slightly resize images with very different original dimensions.
Direction changes which dimension is matched
Vertical stacking matches widths (images can end up different heights); horizontal placement matches heights (images can end up different widths).
Before you rely on the result
- You've added all the images and arranged them in the correct order.
- You've picked vertical or horizontal stitching to match how you want them combined.
- You've previewed the result to confirm the alignment and order look right.
Who this is for
- Anyone combining several screenshots into one long image.
- People joining a sequence of photos into a panoramic-style strip.
- Anyone merging scanned document sections into one continuous image.
Real-world examples
Combining a long chat screenshot
A conversation spans several screenshots taken while scrolling — stitching them vertically produces one continuous image of the whole exchange.
Joining side-by-side comparison shots
Someone has two before/after screenshots and stitches them horizontally into one image for easy side-by-side comparison.
Limitations
- Images are scaled to a common width (vertical) or height (horizontal) so edges line up, which can slightly resize images with very different aspect ratios.
Frequently asked questions
Can I change the order of the images after adding them?
Yes — use the up/down arrows next to each image in the list to reorder them before stitching.
Will my images get resized?
Yes, to a common width (vertical stitching) or height (horizontal stitching) so the edges line up — images with very different original sizes will be scaled to match.
Is there a limit to how many images I can stitch?
You can add as many as you like, though very many large images will take longer to process and produce a larger file.
