SVG Optimizer / Data URI Generator

Optimize SVG, detect risky markup, and copy URL-encoded or Base64 Data URI and CSS background snippets. 100% local.

SVG input

SVG text is processed locally in your browser and is not uploaded to DevCove servers.

This tool does not render or execute SVG in the page. Review risk warnings before using optimized output in production.

Optimize mode

Keeps viewBox, title, desc, role, and aria-* attributes when possible.

Paste or upload SVG text to start.

About this tool

DevCove SVG Optimizer helps frontend developers minify SVG assets without uploading source files. Paste or upload SVG text, run a security pre-check, optimize in Safe or Aggressive mode, and copy Data URI or CSS snippets for inline icons and backgrounds. SVG is never executed in the page preview.

How to use this tool

Use this optimizer when you need smaller SVG assets and copy-paste Data URIs locally:

  1. Paste SVG markup or upload a .svg file.
  2. Review the security pre-check for scripts, event attributes, or external references.
  3. Choose Safe mode by default, or Aggressive for smaller output.
  4. Click Optimize SVG and compare before/after size.
  5. Copy optimized SVG, URL-encoded Data URI, CSS background-image, or Base64 Data URI.

Features

Built for frontend SVG asset workflows:

  • Safe and Aggressive SVGO presets with script element removal.
  • Security pre-check for scripts, event handlers, and external URLs.
  • Optimized SVG plus URL-encoded and Base64 Data URI outputs.
  • CSS background-image snippet for inline icon backgrounds.
  • Before/after byte size comparison.
  • 100% browser-local text processing without SVG execution.

FAQ

Is my SVG uploaded?

No. SVG text is optimized entirely in your browser.

Why is SVG not previewed?

To avoid executing untrusted markup, this tool treats SVG as text only and does not render it in the page.

Safe vs Aggressive?

Safe keeps viewBox, title, desc, and common accessibility attributes. Aggressive minifies more aggressively and may remove them.

Which Data URI should I use?

URL-encoded Data URIs are usually smaller for SVG text. Base64 is optional when a tooling pipeline expects it.

Will risky SVG still optimize?

Yes, but the pre-check lists risky patterns from your source input. Review warnings before using output in production.

How is this different from Image Compressor?

Image Compressor handles bitmap formats. This tool optimizes SVG markup and generates Data URI snippets.
