Best use cases
Use it to quickly inspect SVG snippets, validate copied markup, preview design exports, and check whether an SVG renders before embedding it elsewhere.
What the preview proves
The preview renders through the same sanitized pipeline the site uses everywhere, so what you see is what browsers will safely show — active content stays blocked even if present.
What the inspector reports
SVG Viewer reads the document locally and reports the metrics relevant to this view — structure, values, and counts exactly as they exist in the file.
Reading the results
Treat the output as diagnostics rather than verdicts. Numbers describe the file; whether they matter depends on where the SVG ships and how it is consumed.
