Screenshot Stitcher
Join multiple screenshots vertically or horizontally
Screenshot Stitcher — what it does
Join several screenshots into one long image, vertically or horizontally, with an adjustable gap and background colour between them. Phones and browsers capture one screen at a time, and stitching is how a scrolling conversation, a long form or a full page becomes a single shareable image.
When this tool helps
- Combining scroll captures of a long page or chat into one continuous image.
- Placing before-and-after screenshots side by side for a comparison.
- Building a step-by-step sequence of interface states in one image.
How to use it
- Choose the screenshots in the order they should appear.
- Pick vertical or horizontal stitching.
- Set the gap size and background colour.
- Process and download the stitched image.
Accuracy, limits, and good practice
- Capture with a consistent overlap and crop the repeated strip before stitching, or a duplicated header appears between every section.
- Vertical suits scrolling content, horizontal suits comparisons — matching direction to purpose is most of the work.
- A small gap in a contrasting colour makes the joins deliberate; a zero gap on mismatched captures looks like a rendering error.
Frequently asked questions
Do the images need the same width?
For vertical stitching, matching widths give a clean result. Different widths leave background colour filling the gaps.
How do I capture a whole page in one go?
Most browsers offer a full-page capture in developer tools, which avoids stitching altogether when it is available.
Is there a limit to how many I can stitch?
Memory is the limit. Extremely long results can also exceed what some viewers and platforms will display comfortably.

截圖長圖拼接能做什麼
把多張截圖垂直或水平拼成一張長圖，接縫間距與背景色可調。手機與瀏覽器一次只能擷取一個畫面，而拼接正是讓捲動中的對話、長表單或整頁變成單一可分享圖片的方法。
什麼時候用得上
- 把長頁面或聊天的多張捲動截圖，接成一張連續圖。
- 把處理前後的截圖並排，做成對照圖。
- 把介面各步驟狀態組成一張逐步說明圖。
使用步驟
- 依應出現的順序選擇截圖。
- 選擇垂直或水平拼接。
- 設定間距與背景色。
- 執行處理並下載拼接結果。
精確度、限制與實務建議
- 截圖時保留一致的重疊區，拼接前先裁掉重複部分，否則每段之間都會冒出重複的頁首。
- 捲動內容用垂直、對照用水平——方向配合用途，工作就完成一大半了。
- 用對比色留一點間距，接縫看起來就是刻意的；尺寸不一卻零間距，看起來像算繪錯誤。
常見問題
圖片寬度需要相同嗎？
垂直拼接時寬度一致結果最乾淨。寬度不同時，空隙會以背景色填滿。
怎麼一次擷取整頁？
多數瀏覽器的開發者工具都有整頁擷取功能，能用時就完全不必拼接。
拼接數量有上限嗎？
上限在記憶體。過長的成品也可能超出某些檢視器與平台舒適顯示的範圍。
