Why Use Our SVG Sanitizer?

Remove Scripts

The sanitizer strips <script> tags and inline JavaScript to prevent hidden behavior. This keeps untrusted files safe for dashboards, docs, and public pages, and reduces the risk of unexpected redirects.

Clean Event Handlers

It removes on* attributes and embedded handlers that can trigger actions. This reduces the attack surface when SVGs are shared across tools or embedded in CMS content. It also prevents hover or click behaviors from slipping into production unintentionally.

Block External Links

SVG sanitizer removes unsafe external references and remote resources. The output stays self-contained, which is important for offline usage, internal networks, and predictable builds. This avoids unexpected tracking calls or external dependencies in production.

Safe Preview

Preview the sanitized result so you can verify the artwork after cleaning. This helps you confirm no visual regressions before export and catch missing symbols early. Zoom in on strokes and gradients to confirm the final appearance matches the original. Test on light and dark backgrounds to verify transparency and contrast.

Privacy First

SVG sanitizer runs in your browser, so files never upload. It is a simple security step for client assets, internal brand libraries, and NDA projects.

Instant Cleaning

SVG sanitizer completes in seconds with no setup. Use it as a quick preflight check before publishing or submitting files to review. It is a practical step in security checklists alongside linting and asset review.

How to Sanitize an SVG

1

Upload Your SVG

Drag and drop a file or paste markup to start. The tool loads the source locally and prepares a preview for review, so you can confirm the file before exporting. This is useful when assets come from multiple vendors or shared drives. Open SVG files online and start processing right away.

2

Sanitize the File

Run SVG sanitizer to strip scripts, event handlers, and unsafe references automatically. Review the output to confirm expected visuals and check for missing elements.

3

Export the SVG

Copy or download the sanitized file. The SVG sanitizer keeps filenames intact, so replacing assets in your repo is straightforward and version history remains clear.

SVG Sanitizer FAQ

What does the SVG sanitizer remove from my SVG?
SVG sanitizer removes scripts, event handlers, foreignObject, and unsafe external references that can introduce security risks. It targets elements that execute code or pull remote content. Use SVG sanitizer whenever SVGs originate outside your trusted pipeline. If the file is user-generated, treat it as untrusted by default.
Will sanitizing change how the SVG looks?
SVG sanitizer aims to preserve the visual output. If an SVG relies on removed elements, you may see changes, so always preview. In most icon and illustration files, SVG sanitizer keeps the artwork intact while removing hidden behavior. When issues appear, re-export from the design tool without scripts or embedded HTML.
Does SVG sanitizer remove foreignObject?
Yes. SVG sanitizer removes foreignObject because it can embed HTML and scripts. This keeps output safe for CMS blocks, email templates, and public embeds. If you need HTML inside an SVG, consider exporting PNG instead.
Is the SVG uploaded to a server?
No. SVG sanitizer runs locally in your browser, so files never leave your device. This local SVG sanitizer workflow is safe for confidential assets and strict privacy environments. Local processing also avoids upload limits and keeps review cycles fast.
Can I optimize after sanitizing?
Yes. SVG sanitizer removes risky elements, then optimization can reduce size. Many teams run SVG sanitizer first, then use the optimizer or cleanup to shrink the file further and keep production assets lean. Keeping a sanitized copy alongside the original also helps with audits and review history.
Is this safe for embedding in email or CMS?
SVG sanitizer makes files safer, but each platform has its own rules. Use SVG sanitizer, then follow platform guidelines for allowed tags and attributes. When in doubt, export PNG for platforms that block SVG. Some CMS systems also strip SVG tags automatically, so confirm the final output.
Does it affect accessibility?
SVG sanitizer preserves common accessibility attributes like title and aria-label when safe. After SVG sanitizer runs, you can add or verify labels to meet your accessibility checklist and internal standards. Document those rules so teams stay consistent.
How does this fit into security reviews?
SVG sanitizer provides a fast, repeatable cleaning step for security reviews. It helps teams remove risky content before assets enter production repositories and reduces the attack surface for embedded SVGs in user-facing pages. Consider adding it to your asset intake checklist or CI pipelines. Pair it with a manual spot check for high-risk assets.
Is SVG Sanitizer free to use with no download?
Yes. SVG Sanitizer is free to use in your browser. No downloads or installation are required.
Do I need an account to use SVG Sanitizer?
No. SVG Sanitizer works instantly in the browser without sign-up, and files stay local.
