Where SVG Source Inspector fits

SVG Source Inspector summarizes SVG source length, comments, declarations, root attributes, and raw markup.

Source report

The inspector reports bytes, characters, line count, comments, XML declaration, doctype, and root SVG attributes.

When to use it

Use it before cleanup, optimization, or manual edits when you need to understand the source-level structure of an SVG file.

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 Source 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 Source Inspector provides.

What the inspector reports

SVG Source 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 source into the input panel.
  2. Inspect source. Review source metrics and root attributes.
  3. Copy report. Copy the JSON report when you need to share findings.

Frequently asked questions

Does it rewrite the SVG?
No. This tool inspects and reports source details only.
Does it show comments?
It reports whether comments exist and how many were detected.
Can I copy the report?
Yes. The JSON report is available in the output panel.
Is SVG Source Inspector free?
Yes. SVGKit tools are free to use with no account required.
Does SVG Source 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.
