What is SVG?
SVG (Scalable Vector Graphics) is an XML-based image format for describing geometric shapes. Unlike JPG and PNG, which are bitmaps (pixel matrices), SVG uses tags like <rect>, <circle>, and <path> to describe mathematical paths of shapes, meaning they stay sharp at any size without pixelation.
**When should you use SVG?** Logos, UI icons, flowcharts, map markers, charts, animated decorations, and reusable illustrations—any scenario demanding clarity, color customization, scalability, or CSS control is a natural fit for SVG.
**SVG vs Canvas:** Canvas is an imperative drawing API where output becomes pixels; SVG is declarative DOM nodes where you can modify attributes, CSS styles, and attach events at any time. Use SVG for icons, UI elements, and interactive graphics; use Canvas for games, particles, and pixel art.
**Common components:** <svg> root element, <g> groups, <path> paths (most commonly used with d attribute), gradients (<linearGradient>/<radialGradient>), filters (<filter>), and animations (SMIL/CSS/JS).
**How to preview it?** Paste your SVG source code into the editor on this page and see the live render on the right. The draggable split-pane layout helps you verify in seconds that your SVG code is correct and displays as expected.
Use Cases
- Frontend developers quickly previewing SVG icon code rendering
- Verifying SVG display after copying from Figma, Sketch, or other design tools
- Live previewing changes while debugging SVG paths, colors, or viewBox attributes
- Reviewing and validating SVG code before integrating into project code
How to Use
- Paste SVG source code into the left editor, or click "Load Sample" to see a demo
- The right pane instantly renders the vector graphic—edit code to see live updates
- When satisfied, click copy to copy source, or download as .svg with a custom filename

FAQ
How do I preview SVG code online?
Paste your SVG source code into the left editor pane, and the right pane will instantly render the vector graphic. You can edit code directly in the editor with live preview updates, making it easy to debug frontend icons and verify effects.
How do I download and save the previewed SVG?
Click the download button in the preview pane's top-right corner. You can customize the filename before saving as a standard .svg file. You can also click the copy button to copy SVG source code directly to your clipboard for pasting into your project.
Is my SVG code uploaded to a server? Is it secure?
No. All SVG parsing and rendering happens locally in your browser. Your SVG code is never uploaded to any server—it's processed entirely on your device and discarded when you leave, eliminating any risk of leaking unreleased icon assets or design drafts.
Does it support SVG copied from design software?
Yes. SVG code copied from Figma, Sketch, Adobe Illustrator, or other design tools can be pasted directly for preview. We recommend checking the rendered result first to confirm correctness before integrating into your project.
Why isn't my SVG showing? Common causes?
Common issues: ① Missing xmlns="http://www.w3.org/2000/svg" namespace declaration; ② Unclosed tags in the code; ③ Special characters not properly escaped; ④ Syntax errors in the SVG itself. Please check these items first.
Can I customize the downloaded SVG filename?
Yes. After clicking the download button, a filename input field appears. You can customize the name (defaults to image.svg), then press Enter or click Confirm to download. The tool automatically appends the .svg extension if missing.
Glossary
- viewBox
- The SVG internal coordinate system in the format "x y width height". Common "0 0 24 24" means 24 units wide and tall. The actual display size of an SVG is controlled by width/height attributes or external CSS.
- XML Namespace
- SVG must declare xmlns="http://www.w3.org/2000/svg" for browsers to correctly recognize it as an SVG document. Missing namespace is the most common reason SVG doesn't display in HTML.MDN - SVG Namespace
- path d attribute
- The path command set, consisting of letters like M/L/C/Q/H/V/Z plus coordinates. M=Move to, L=Line to, C=Cubic Bézier, Q=Quadratic Bézier, Z=Close path. Complex icons are often expressed with just one path element and its d attribute.
- currentColor
- A CSS keyword referring to the current element's color property. Setting fill or stroke to currentColor in SVG lets you change icon colors via external CSS color changes—a common design system pattern.
SVG Common Elements Reference
| Element | Type | Purpose |
|---|---|---|
<svg> | Root | Container for all SVG content, required |
<rect> | Basic Shape | Rectangles, rounded rectangles |
<circle> / <ellipse> | Basic Shape | Circles / ellipses |
<line> / <polyline> | Basic Shape | Lines / polylines |
<polygon> / <path> | Path | Polygons / arbitrary curves (d attribute) |
<text> / <tspan> | Text | Text embedded in SVG |
<g> | Group | Group elements for unified transforms |
<defs> / <symbol> | Definition | Reusable shapes and gradients |
<linearGradient> / <radialGradient> | Gradient | Linear / radial gradient fills |
<use> | Reference | Reference elements from defs |
<filter> | Filter | Advanced effects like blur, shadow |
SVG vs Bitmap Formats Comparison
| Dimension | SVG (Vector) | PNG (Bitmap) | JPG (Bitmap) |
|---|---|---|---|
| Composition | XML describes geometric paths | Pixel matrix | Pixel matrix (DCT compression) |
| Scaling | Stays sharp at any size | Pixelates when scaled up | Pixelates with visible artifacts |
| File Size | Varies by complexity, logos usually < 10KB | Medium (lossless) | Smaller (lossy) |
| Transparency | ✅ | ✅ | ❌ |
| Animation | ✅ SMIL / CSS / JS | ❌ (requires APNG) | ❌ |
| CSS Color Control | ✅ currentColor / fill variables | ❌ | ❌ |
| Best For | Icons, logos, UI vectors | Transparent assets, screenshots | Photos, large gradients |
