Change the size, keep the drawing
An SVG has two sizes: the width and height your software reads, and the viewBox, the drawing’s own grid. This tool changes only the width and height, so the drawing scales evenly and nothing inside it moves. The file needs a viewBox already. The tool can’t trim empty space, fix paths or set cut and score lines. With Keep proportions off, a size that doesn’t match the drawing’s shape adds space around it, or crops it in some programs; it never stretches the drawing.
