Methods & limits
Normalize one dimension, then arrange along the reading direction
Vertical mode gives every image the same width—ideal for chat captures, instructions, and dialogue. Horizontal mode gives them the same height for bursts, mood boards, and sequences.
Canvas limits vary by browser. The tool scales the complete result when its long side exceeds 16,000 px or its pixel area becomes unsafe; it does not promise unlimited dimensions.
Vertical height = Σ (shared width × source height ÷ source width) + gaps; horizontal mode swaps width and height.
FAQ
Long image stitcher · FAQ
How do I make a seamless long screenshot?
Set the gap to 0 and order captures as they appear. Crop repeated overlap first; this tool does not detect or remove it.
Will it reduce quality?
Normal-size results export as PNG. Only canvases beyond safe browser limits are scaled proportionally, and the page states that boundary.
Why not merge overlapping regions automatically?
Panorama blending can distort text and interfaces. This tool prioritizes faithful screenshot layout.
