What it cleans

The cleaner removes comments, script elements, metadata blocks, and inline event handler attributes, then adds the standard SVG namespace.

Conservative scope

This first version avoids geometry changes. It focuses on source cleanup and practical safety issues before deeper optimization.

Findings report error — missing viewBox warning — script element found ok — markup parses cleanly Fix hard failures first, judge style findings in context, then re-run for a clean report. every finding states what it means.
SVG Cleaner reports findings with severity and context — fix hard failures first, then re-run for a clean report.
A findings report with error, warning, and ok rows next to a magnifier, illustrating how SVG Cleaner reports structural findings.

What gets checked

SVG Cleaner parses the document locally and validates it against structural rules and this tool's focus area, reporting each finding with enough context to locate it.

Common findings and fixes

Typical issues include missing viewBox attributes, duplicate IDs, unsafe active content, and deprecated structures. Most have a direct fix in the matching edit or optimize tools.

Severity and manual review

Parse errors and unsafe content are hard failures; style-level findings need judgment based on where the SVG ships. Automated checks complement, not replace, a visual review.

Privacy

Validation runs locally in your browser. Files are parsed in the page and never uploaded.

How to use

  1. Paste SVG. Paste SVG markup with comments, metadata, scripts, or event handlers.
  2. Clean source. The tool removes common unsafe or noisy items.
  3. Copy cleaned SVG. Copy the cleaned SVG for further editing or optimization.

Frequently asked questions

Does it sanitize every possible SVG risk?
No. It handles common high-signal issues. Treat untrusted SVG with defense in depth.
Does it remove visible shapes?
It is designed to preserve visible SVG geometry while removing noisy or unsafe source items.
Should I optimize after cleaning?
Yes. Use SVG Optimizer when you also want file-size reduction.
Is SVG Cleaner free?
Yes. SVGKit tools are free to use with no account required.
Does SVG Cleaner upload my files?
No. The tool runs entirely in your browser, so your files never leave your device.
Which standards does it check against?
The SVG specification plus the specific rules this tool focuses on. Findings reference the rule so you can judge each one.
Does it fix problems automatically?
No. Validation reports findings; the edit and optimize tools apply the fixes.
Can it produce false positives?
Rarely. When a finding does not apply to your context, note it and move on — the tool cannot see how the SVG is consumed.
