Where SVG Compatibility Checker fits

SVG Compatibility Checker finds SVG features that may behave differently across browsers, renderers, and export pipelines.

Feature checks

The checker reports filters, foreignObject, masks, clipPaths, animation elements, and blur filters that commonly need compatibility review.

When to use it

Use it before shipping SVGs into emails, PDFs, print workflows, design tools, or non-browser rendering systems.

What gets checked

SVG Compatibility Checker 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 advanced features.
  2. Review report. Check detected compatibility caveats.
  3. Adjust source. Simplify or rasterize risky features for your target pipeline when needed.

Frequently asked questions

Does this prove browser support?
No. It flags features that deserve review. Final support depends on the target renderer.
Does it remove incompatible features?
No. It reports compatibility risks only.
Does it detect filters?
Yes. Filter elements and filter attributes are included.
Is SVG Compatibility Checker free?
Yes. SVGKit tools are free to use with no account required.
Does SVG Compatibility Checker 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.
