Add 2-20 screenshots. Choose Vertical for top-to-bottom output or Horizontal for left-to-right output. Reorder files and the preview refreshes without a separate create button.
Prepare captures
Use the same device orientation when possible and remove private notifications. Crop duplicate overlap before uploading when a seamless transcript matters.
Choose direction and order
Vertical mode normalizes width; Horizontal normalizes height. The first list item becomes the top or left image. Drag items or use arrow buttons to correct the sequence.
Set size and spacing
1080 px is a clear default. Zero spacing joins continuous screens, while a small gap separates independent captures. PNG keeps interface text crisp; JPG is often smaller.
Respect canvas limits
The tool checks dimensions before rendering. If the result exceeds 40 megapixels or a 32,000-pixel side, reduce normalized size, remove unnecessary screens or export in two parts.
Review and download
The download comes from the displayed rendered result, so direction, order, proportions, gap and background match the preview.
