Trying to stitch multiple chat screenshots into one long image to share on social media? Need to combine tutorial step screenshots into a single guide? Or maybe you want to merge several product photos into a comparison collage?

Image stitching (also called long image creation) is one of the most common everyday image-editing tasks. In the past, you might have taken screenshots on your phone and manually pieced them together — only to end up with blurry results, images in the wrong order, or uneven spacing. Here's a smarter way.

Common Use Cases for Image Stitching

  1. Chat history sharing — Stitch multiple WhatsApp/Telegram chat screenshots into one long image for easy forwarding
  2. Tutorial walkthroughs — Combine step-by-step screenshots into a single visual guide
  3. Product comparisons — Join several product photos side-by-side for quick comparison
  4. E-commerce listings — Stack product images vertically to create a complete listing detail page
  5. Social media — Create long-image covers for Instagram posts or stories to improve engagement

Vertical vs Horizontal Stitching

Method Best For Pros Cons
Vertical Chat screenshots, tutorial steps Natural scroll-down reading experience Very long images can be slow to load
Horizontal Product comparisons, panoramas Intuitive left-to-right comparison Limited by screen width

Step-by-Step: Stitch Images with PixelForge

Head over to PixelForge's image stitching tool and follow these steps:

Step 1: Upload your images Drag and drop the images you want to stitch. Supports PNG, JPEG, and WebP formats.

Step 2: Arrange the order After uploading, drag to reorder images so they appear in the correct sequence.

Step 3: Adjust stitching settings

  • Direction: Choose vertical or horizontal stitching
  • Spacing: Set the gap between images (2–5px is recommended)
  • Background color: Pick a color for the gaps between images

Step 4: Download Click "Stitch," preview the result, and download your long image.

Pro Tips for Better Long Images

  1. Uniform width first — Before stitching, crop all images to the same width for a cleaner, more professional result
  2. Trim chat headers and footers — Use a crop tool to remove the top title bar and bottom input bar from chat screenshots before stitching
  3. Add annotations — After stitching, use a filter or overlay tool to add text labels or arrows to your long image
  4. Watch your file size — Long images can get very large. Run the finished result through a compression tool to optimize it

FAQ

My stitched image is too long. What should I do?

Split the content into smaller batches, or only include the most important screenshots. We recommend keeping stitched images to 10 screenshots or fewer.

The stitched image looks blurry — how do I fix it?

Make sure your original screenshots are clear. Stitching doesn't lower image quality, but if your source images have low resolution, they'll appear blurry when viewed at full size.

Can I stitch images of different sizes?

Yes. The tool automatically aligns them. For vertical stitching, the widest image sets the width. For horizontal stitching, the tallest image sets the height.

Is it safe to use an online image stitching tool?

It depends on the tool. Never upload sensitive chat screenshots to a server-based tool. Use a browser-local tool like PixelForge — your images are processed entirely on your device, so they never leave your computer.
