What is long image stitching?
Long image stitching means joining several screenshots or photos end to end, in order, into one continuous tall (or wide) image. It is the fastest way to show content that should be read as a whole and not be auto-cropped by a chat app or social platform — a full conversation, a step-by-step tutorial, or a report that needs to be seen in one pass.
Compared with sending images one by one, a stitched long image keeps the order intact, lets the reader scroll through it in a single swipe, and is easier to archive. Collage Pro stitches everything locally in your browser: images are never uploaded to a server, so it stays fast and is well suited to private chat logs or internal material.
The tool supports both vertical stitching (the most common choice for chat logs and tutorials) and horizontal stitching (better for timelines, before-and-after pairs, and wide panoramas). You can reorder each image, adjust spacing and background, and export a crisp result that does not look blurry.
Common use cases
Stitch chat screenshots
Combine multi-screen WhatsApp, iMessage, or email captures into one vertical record for evidence, archiving, or forwarding — without the order getting scrambled.
Tutorials and step guides
Join step screenshots in sequence so readers follow the whole flow in one scroll. Better than a grid when the steps have a clear order.
Product detail images
Stack product shots, specs, and selling points into a single long detail image for store pages, social posts, or direct sharing.
Reports and data captures
Merge multiple charts, tables, or dashboard captures into one report image you can drop into a doc or a group chat without explaining each one.
Vertical or horizontal? Stitching tips
- Use vertical stitching for content with a fixed reading order — chat logs, tutorials, long-form posts — it feels most natural on a phone.
- Use horizontal stitching for timelines, before-and-after pairs, and wide scenes, but remember it shrinks on mobile, so avoid dense text.
- Match the width (vertical) or height (horizontal) of your captures first so the seams line up without gaps or offsets.
- Leave 2–8px of spacing to separate sections clearly; set spacing to 0 when you need a seamless long image.
- Export text-heavy images as PNG to keep type sharp; use JPG 90% for photo-heavy stitches to keep the file smaller.

Frequently asked questions
Does this work for chat screenshots?
Yes. Chat logs and tutorial screenshots are among the most common use cases. Multi-screen captures stitch vertically in order for easy reading and archiving.
Can I stitch horizontally too?
Yes. You can switch between vertical and horizontal stitching in the tool — horizontal works well for timelines and before-and-after comparisons.
How many images can I stitch at once?
There is no fixed limit. Anywhere from a few to several dozen screenshots works; the more you add the taller the result, so double-check the order before exporting.
Will the stitched long image look blurry?
No. Images are stitched at their original resolution with high-quality export. For text-heavy content, export as PNG to keep type crisp.
Can the seams be seamless?
Yes. Set spacing to 0 for a seamless long image, or increase it when you want visible separation between sections.
Are my screenshots uploaded anywhere?
No. The entire stitch happens locally in your browser; images are never sent to a server, which suits private chat logs and internal material.
Do I need to install anything?
No. The full workflow runs directly in the browser on both phone and desktop.
