The most common request when combining screenshots into one image is vertical stitching: arranging chat logs, shopping lists, and long web pages top-to-bottom into a single scrollable long image. Compared to horizontal stitching, vertical matches phone reading habits and is the mainstream way to share and archive. Here's a complete tutorial.
When Vertical Stitching Makes Sense
- Chat logs — combine a conversation that doesn't fit one screen into a single long image for sharing or evidence
- Shopping lists/orders — stack multiple order screenshots vertically
- Long web pages/articles — scroll and capture several screenshots, then stitch
- Notes/course screenshots — merge vertical note screenshots into one long image
Vertical vs Horizontal Stitching
| Aspect | Vertical | Horizontal |
|---|---|---|
| Direction | Top to bottom | Left to right |
| Best for | Chat logs, long screenshots, vertical content | Panoramas, tables, wide content |
| Reading | Matches phone portrait | Requires sideways scroll |
Chat logs and screenshots must be vertical — horizontal output is unreadable.
How to Stitch Screenshots Vertically
Open the PixelForge Image Stitch tool:
Step 1: Upload screenshots in order — add them top-to-bottom; the tool arranges them automatically.
Step 2: Choose vertical stitching — the tool joins them from top to bottom in upload order.
Step 3: Adjust the join — leave a small gap or butt them flush, whatever you prefer.
Step 4: Download the long image — one complete scrollable image.
Three Key Vertical Stitch Tips
- Keep the order straight — upload in reading order; the tool follows upload order strictly
- Trim redundancy first — crop repeated scrollbars and duplicated content from each shot with the multi-size crop tool for a cleaner result
- Watch the length — keep it under ~20 screens; longer images get huge and platforms may compress or reject them when sharing
After Stitching
Stitched long images run large — run them through the Smart Compress tool so WeChat, Twitter, and other platforms send them smoothly.
