Browser-local SVG Processing

The Repair SVG utility processes SVG content in your browser. The raw SVG is not uploaded for processing; actual processing time depends on the file and your device. See the Privacy Policy for normal website requests and hosting logs.

About Repair SVG

Corrupted SVG files, syntax errors from manual edits, or bad exports can prevent vectors from loading correctly. Our SVG Repair tool parses raw markup, identifies missing dimensions, adds missing viewBoxes, fixes unclosed tags, and strips unsafe scripts using client-side DOM parsing. It generates a detailed repair report so you can verify exactly what structural fixes were applied.

How It Works

01

Paste your malformed or unrendering SVG text.

02

Read the generated Repair Report indicating XML syntax issues, viewBox additions, or structure corrections.

03

Download the functional, browser-compatible version.

Markup repair notes

Use Repair SVG when malformed markup, a broken export, or missing document structure prevents an asset from rendering as expected. The tool reports the repaired output, but the result should still be tested in the browser and workflow where the SVG will be used.

What this tool does

  • Parses the supplied SVG and repairs supported structural problems such as missing or unclosed markup.
  • Can establish missing sizing information or a viewBox when the source contains enough dimensions to infer it.
  • Removes unsafe script nodes as part of the browser-side repair path and presents the result for review.

Review before publishing

  • A parser can recover structure without knowing the designer’s intended geometry, cropping, or layer semantics.
  • External references, filters, fonts, and embedded content may still need manual inspection after repair.
  • Keep the original damaged file so a repair can be compared or repeated with different assumptions.

Broken input

<svg width='24' height='24'>
  <path d='M3 12h18'
</svg>

Repaired structure (illustrative)

<svg width='24' height='24' viewBox='0 0 24 24'>
  <path d='M3 12h18'/>
</svg>

Frequently Asked Questions

How does the repair engine fix malformed XML?

It parses the markup through a browser-based DOM parser. The browser's native parser is excellent at auto-correcting open tags, missing quotes, and structural hierarchy, which we then extract and format.

Why won't my SVG render in HTML?

Common culprits include missing viewBox attributes, namespaces missing from custom elements, or unescaped characters in inline attributes. This tool automatically patches these issues.

Can this tool fix missing viewBox attributes automatically?

Yes, if width and height are specified, it calculates the viewBox coordinates. If not, it applies a safe default viewBox space so the vector can scale properly.
