Does it crop the SVG?

Changing the viewBox changes the visible coordinate window, so content outside that window is clipped in the preview.

What if width and height are missing?

It falls back to a 100 by 100 viewBox.

Yes. Edit minX, minY, width, and height while watching the live preview. Automatic geometry fitting is not included.

Page context

SVG ViewBox Adjuster inspects the SVG viewBox and creates a default one from width and height when missing.

The viewBox defines the internal SVG coordinate system. Without it, responsive scaling and editing are harder.

If no viewBox exists, the tool creates `0 0 width height` from numeric width and height values.
