SVG viewer & editor specification

Version 1.0.0 · Last reviewed 2026-07-28

Definition
An SVG viewer/editor previews Scalable Vector Graphics markup and lets you tweak paths locally in the browser.
What it calculates
Parses SVG markup for preview and basic editing without uploading files to a server.
Inputs
  • SVG markup or file contents
Outputs
  • Rendered SVG preview and editable source
Formula
preview = SVG DOM render of source text

The SVG Viewer & Editor renders Scalable Vector Graphics (SVG) code in the browser. Paste SVG markup in the code panel and see the vector graphic update in the preview panel.

What is SVG?

SVG (Scalable Vector Graphics) is an XML-based format for vector images. Unlike raster formats (JPEG, PNG), SVG scales to any size without quality loss.

Basic SVG example

<svg width="200" height="200" xmlns="http://www.w3.org/2000/svg">
  <circle cx="100" cy="100" r="80" fill="blue" />
  <text x="100" y="105" text-anchor="middle" fill="white" font-size="20">
    SVG
  </text>
</svg>

Using the tool

  1. Paste SVG code in the Code panel
  2. View the rendered graphic in the View panel
  3. Edit the code to modify shapes, colors, and text
  4. Copy the final SVG for use in HTML, CSS, or design tools

SVG in HTML

<!-- Inline SVG -->

</svg>

<!-- External SVG file -->
