SVG ViewBox Inspector reports root viewBox coordinates, dimensions, and aspect ratio.

Coordinate report

The tool parses minX, minY, width, and height from the root viewBox and calculates the aspect ratio.

Use cases

Use it when debugging cropped artwork, scaling issues, icon alignment, or responsive SVG behavior.

Read-only diagnostics, computed locally your document Report elements · bytes · viewBox · ids exactly as parsed — nothing uploaded Diagnostics, not verdicts: judge findings where the SVG ships.
SVG ViewBox Inspector reports metrics exactly as parsed in your browser — diagnostics to act on, not verdicts.
A document flowing into a metrics report with element, byte, and viewBox counts, illustrating the read-only diagnostics SVG ViewBox Inspector provides.

What the inspector reports

SVG ViewBox Inspector 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.

When the findings matter

They matter most at handoff: before publishing, before optimizing, and when a file from an unknown source needs a quick structural look.

Privacy

Inspection runs locally in your browser. The document is analyzed in the page and never uploaded.

How to use

  1. Paste SVG. Paste SVG markup with a root viewBox.
  2. Inspect coordinates. Review minX, minY, width, height, and aspect ratio.
  3. Copy report. Copy the JSON report if needed.

Frequently asked questions

Does it edit the viewBox?
No. It reports the current root viewBox.
What if the viewBox is missing?
The tool reports that no valid root viewBox was found.
Does it measure rendered bounds?
No. It parses the source coordinate system.
Is SVG ViewBox Inspector free?
Yes. SVGKit tools are free to use with no account required.
Does SVG ViewBox Inspector upload my files?
No. The tool runs entirely in your browser, so your files never leave your device.
How accurate are the results?
They reflect the document exactly as parsed in your browser — the same engine that renders it.
Does it fix anything?
No. Inspection is read-only; pair it with the matching editor or optimizer tool to act on what you find.
Does it work on minified files?
Yes. Formatting does not affect parsing, so compact and pretty-printed files report the same.
