Posting long images on social media, laying out articles, saving chat logs as long images, combining step-by-step screenshots into a tutorial image… image stitching (collage) is super useful. Previously you needed professional software; now online stitching tools work right in the browser. Here's how.
Common uses of image stitching
- Chat log long image: combine a long sequence of chat screenshots into one
- Vertical stitch: combine portrait images into one long portrait
- Horizontal stitch: combine images side by side into a wide image
- Merge into one: combine loose images for easy sharing
- Step tutorial image: combine screenshots into a teaching image
Choosing an online stitching tool
A good online tool should offer:
- Horizontal and vertical stitching: both directions
- Adjustable spacing and alignment: controlled gaps, neat alignment
- Batch upload: add all images at once
- Free reordering: adjust image order
- Local processing: privacy-safe, no uploads
PixelForge Image Stitch covers all of the above — free, batch, browser-local.
Steps to stitch online
Step 1: Upload
Drag multiple images into the upload area.
Step 2: Choose direction
Choose vertical (stacked, good for chat logs) or horizontal (side by side, good for wide images).
Step 3: Adjust order and spacing
Drag to reorder and set gaps between images for a clean result.
Step 4: Generate and download
Generate the combined image and download.
Long-image tips
- Capture complete chats first: screenshot the full conversation before stitching to avoid gaps
- Unify width: images of matching width give a cleaner result
- Control spacing: reasonable gaps keep it clean; too much wastes space, too little looks cramped
If the stitched image is too large, compress it with Smart Compress before sharing.
