Chat Screenshot Stitching
Stitch multiple chat screenshots into one continuous long image for evidence preservation or sharing.
Whether you're saving proof of a conversation or turning a long WhatsApp or iMessage thread into one shareable image, stitching individual screenshots together by hand is slow and easy to mess up.
The Problem
Long conversations force you to take screenshot after screenshot, since each one only captures what fits on your screen at that moment. Keeping dozens of separate images makes it hard to review the conversation later, and sending them one by one means the recipient has to open each file in the right order just to follow the thread. This is especially frustrating when you need a single clean image for evidence, a support ticket, or a work record, and losing track of order breaks the context completely.
The Solution
Drag all your ordered screenshots into Auto Merge Images and it automatically detects each image's width and aligns them edge to edge. Set the gap to zero and it stitches every screenshot into one seamless, continuously readable image, with chat bubbles lining up as if it were one native long screenshot. Everything runs locally in your browser, so your conversation never touches a server.

Frequently Asked Questions
Can I merge screenshots from any messaging app?
Yes. The tool only processes the images themselves, so WhatsApp, iMessage, Slack, Discord, SMS, or email screenshots all work the same way, as long as you arrange them in conversation order.
Will the images automatically align even if screen widths differ slightly?
Yes. The tool detects each screenshot's width and aligns them to the widest one, and setting the gap to zero removes visible seams between images.
Is there a limit to how many screenshots I can stitch together?
There's no fixed limit. Since everything processes locally in your browser, the practical limit depends on your device's memory, but merging dozens of screenshots works fine in practice.
Can I use this for long scrolling web page screenshots too?
Absolutely. The same stitching technique works for scrolling screenshots of web pages, articles, or social media feeds, just drop the sequential captures in and merge them the same way.
