How to Stitch Screenshots Together into One Long Image
Published: 2026-09-22
You've probably been there: a long chat conversation, a multi-step tutorial, or a full web page that takes 3-4 screenshots to capture. Sharing them as separate images is annoying — viewers have to scroll and piece them together mentally. The solution is a long screenshot stitcher.
What Is a Long Screenshot?
A long screenshot (also called a scrolling screenshot or full-page capture) combines multiple vertically stacked images into one tall image. It's popular on Xiaohongshu, WeChat articles, Twitter threads, and documentation.
Why Not Use a Phone's Built-in Feature?
Both iPhone and Android have built-in scrolling screenshot now, but they have limitations:
- iPhone's Full Page capture only works in Safari, and exports as PDF
- Android's scrolling capture often cuts off at app boundaries
- Neither lets you stitch screenshots taken on different devices
Our Browser-Based Stitcher
Our Long Screenshot Stitcher lets you drop any number of screenshots, adjust the gap between them, and download one tall PNG. Everything runs in your browser — no upload, no watermark.
