How to Stitch a Long Image for Xiaohongshu? Three Steps to a Note That Scrolls
Xiaohongshu notes often use vertical long images to show several steps or products. Here is how to go from picking images to exporting a long image made for scrolling.
I made a "one week of outfits" note; posting nine photos separately looked messy, and stitching them into one long image felt like a puzzle. Xiaohongshu users expect to scroll down through the whole thing, which is exactly what a long image fits. Here are the three steps I use.
Step 1: unify the width and the order
Keep every asset the same width (1080px or 1242px is common) so the stitched result does not end up with a stair-step look. Work out the order in your head first — cover, then the steps, then the summary — before you start stitching.
If one image has the wrong dimensions, use Resize Image to line the widths up. When you want to emphasise one shot, crop it with Crop Image — rectangular crops only, no custom shapes.
Step 2: stitch vertically
Open Stitch Images Into a Long Image, upload the images in order and pick the vertical mode. TwoThink composites them locally in your browser, so the images are not uploaded to a server, which suits notes featuring unreleased products or personal photos.
If you only have two or three landscape shots to place side by side, the grid mode in Merge Images does the job; but vertical long images are far more common in Xiaohongshu notes.
Step 3: compress and export
A stitched long image can reach 5–10MB, so run Compress Image once before publishing — it loads faster. If a public note contains shooting information, remember Remove Image Metadata so the location and device details do not leak.
Common pitfalls
- Dragging them out of order: number the file names before you start, or sort by capture time
- One section too tall: a single endless strip gets tiring to scroll, so split it into two or three long images
- Text too small: if the source resolution is low the stitched result is only blurrier — keep the source sharp and do not expect stitching to "make it clearer"
Try it → open Stitch Images Into a Long Image, pick three or four portrait images, stitch them vertically and see how the scroll feels.
