How to do long picture splicing: Chat screenshots and product details multi-picture splicing tutorial
Upload and drag to sort up to 20 pictures locally in the browser, select vertically long pictures or horizontally wide pictures, unify the width/height, or retain the original size and set spacing, margins, rounded corners and background. The default zero spacing only allows images to be arranged adjacently and does not automatically delete overlapping content in screenshots.

Operation path
How to sort, splice and check long images
- Upload 2 to 20 JPG, PNG, WebP or BMP pictures, and adjust the order by dragging.
- Select vertical or horizontal splicing, and decide to automatically match the width/height or retain the original size, and then set the spacing, margins and background.
- Preview the export size and select JPG, PNG or WebP for download; if the prompt has been reduced, you should recheck the text clarity and target platform limitations.
Seamless, Zoom and Browser Limitations Instructions
- The so-called seamless means that the spacing is set to 0 and then drawn adjacently. Duplicate content in the two screenshots will not be automatically identified or deleted.
- The automatic matching mode will scale the picture to a uniform width or height; when retaining the original size, pictures of different sizes will be centered on the background and may produce white space.
- An extremely long canvas may trigger browser memory or Canvas limitations. The current tool will reduce the export proportionally when the safe side length or number of pixels is exceeded.

Frequently asked questions
Long picture splicing common problems
How many long images can be stitched together at most?
Currently, a maximum of 20 JPG, PNG, WebP or BMP images are supported at a time. The larger the image size, the more browser memory it takes up.
Why can duplicate content or seams still be seen after splicing?
The tool draws pictures directly according to sorting and spacing, and does not recognize the overlapping areas of screenshots. Differences in original image edges, colors, scaling, or duplicate content may make joints visible.
Will super long pictures maintain their original size?
Not necessarily. If the result exceeds 32,000 pixels on a side or about 120 million pixels, the tool will scale it down to reduce the risk of browser Canvas export failure.
