About this tool
Stitch screenshots, chat records or product photos into a single long image. Stack them vertically or line them up horizontally, set the gap and background, choose how the uneven edges should align, and normalise the sizes so the result has no ragged border. Useful for sharing a whole conversation or an entire page as one file.
How to use it
- 1Drop the images in the order you want them stacked, and reorder with the arrows if needed.
- 2Choose the direction, the sizing rule and the gap; the preview updates as you change them.
- 3Download the stitched image as PNG, JPEG or WebP.
Frequently asked questions
Why are my images different widths?
Screenshots from different devices rarely share a width, and stitching them unmodified leaves a stepped edge. The sizing rule fixes this: pick the widest or the narrowest image to scale everything to, or type an exact width.
Is there a size limit?
Yes, and it is imposed by the browser rather than by us. A canvas beyond roughly 30,000 pixels on a side cannot be allocated, so when the result would exceed that the tool scales everything down proportionally and tells you it has done so.
What does the alignment option do?
It decides where each image sits across the axis it is not stacked along. With images of equal width it changes nothing; with mixed widths, centring gives a balanced look while start or end keeps one edge perfectly straight for a banner-like result.
