Merging multiple images into one is super common — stitching chats into long images, combining screenshots, or making photo grids. Here's how to use an image stitching tool to merge images into one.

When to stitch images

  • Chats: merge multi-screen chats into one long image for sharing
  • Screenshots: combine them for saving and viewing
  • Photo collages: merge photos for sharing
  • Design assets: combine images for layout

Stitching combines a series into one image, making it easy to share and archive.

Three stitching modes

Vertical: stack images top to bottom — best for chats, screenshots, and vertical content.

Horizontal: place images side by side — for horizontal content and panoramas.

Grid: arrange into nine-grid or tiled layouts — for photo collections.

FAQ

How do I stitch chats into one long image?

Upload each chat screenshot to the [Stitch Tool](https://img-tools.top/stitch) and choose vertical stitching — it combines them into one complete long image for one-tap sharing.

Does stitching change image quality?

No. Stitching just combines images without compressing pixels. Long images are large, so compress before sharing if needed.

Can I make a nine-grid photo collage?

Yes. Choose the grid mode and upload your photos to create nine-grid or tiled layouts, great for photo collections and social sharing.

What if the stitched image is too long to view?

Long images auto-scale on phones. You can also re-crop or split them, and compress them to fit platform size limits.
