SVG is code you can edit in a text editor — but seeing the result requires a live preview. Use our free SVG Code Previewer to paste SVG markup and render it instantly, with background toggles, prettify, and download.
What Is SVG?
SVG (Scalable Vector Graphics) is a code-based image format that stores shapes mathematically rather than as pixels. Unlike raster images like PNG or JPG, SVG scales perfectly to any size — making it ideal for icons, logos, illustrations, and UI elements that need to look sharp on any screen density.
When to Use a Live SVG Previewer
- Checking exports — verify an SVG from Figma or Illustrator before embedding it in code
- Manual editing — tweak paths, colors, or dimensions and see results instantly
- Debugging — inspect and fix an SVG that doesn't display correctly
- Background testing — see how an icon looks on light, dark, or transparent backgrounds
SVG vs PNG/JPG
SVG is text you can edit in a code editor and style with CSS or JavaScript. PNG and JPG are pixel grids you edit in image software. SVG excels at icons and geometric art; PNG/JPG excel at photographs. When you need a raster version, see our guide on how to convert SVG to PNG online.

Frequently Asked Questions
What is SVG and why is it used for web icons?
SVG (Scalable Vector Graphics) is a code-based image format that stores shapes mathematically rather than as pixels, allowing it to scale to any size without losing quality — ideal for icons, logos, and UI elements that need to look sharp on all screen resolutions including high-DPI/Retina displays.
Can I edit SVG colors and sizes without an image editor?
Yes — SVG is just XML/text, so you can directly edit the fill, stroke, width, and height attributes in the code and see the result instantly in a live previewer.
Is it safe to paste SVG code from the internet into a previewer?
Exercise caution — SVG can contain embedded JavaScript that may run when rendered. A good SVG previewer sanitizes the input by stripping script tags and event handlers before rendering; this tool does that. Still, only paste SVG from trusted sources.
How is SVG different from PNG?
SVG stores images as mathematical descriptions of shapes (lines, curves, fills) while PNG stores a fixed grid of pixels. SVG scales perfectly at any size, PNG loses quality when scaled up — but PNG handles photographic images better than SVG, which is best suited for icons, logos, and geometric illustrations.
