What is SVG? Complete Guide and Online Editor

SVG (Scalable Vector Graphics) is an XML-based vector graphics format defined by W3C standards. Unlike traditional bitmap images (PNG, JPEG), SVG uses mathematical descriptions to define graphics, meaning they maintain perfect clarity at any resolution while keeping relatively small file sizes.

Why Choose SVG? Core Advantages Analysis

Lossless Scaling

SVG graphics maintain perfect clarity at any size, adapting to various devices and screen resolutions

Small File Size

Compared to bitmaps, simple SVG graphics are usually smaller, reducing webpage load times

Fully Editable

Can be edited directly through code, supports CSS styling and JavaScript interaction

SEO Friendly

Search engines can index text content within SVG, improving website SEO performance

Animation Support

Native support for CSS and SMIL animations, creating rich interactive effects

Accessibility

Supports alt text and semantic tags, providing better accessibility experience

Practical SVG Use Cases

Frequently Asked Questions

Can SVG files be used in all browsers?

Modern browsers (IE9 and above, Chrome, Firefox, Safari, Edge) all support SVG. For older browsers, you can provide PNG fallbacks.

When should I use SVG instead of PNG?

Choose SVG when graphics are relatively simple, need scaling, or require small file sizes. Complex images and photos are still better suited for PNG or JPEG.

How to ensure SVG accessibility?

Use title and desc tags to add descriptions, add appropriate ARIA labels to interactive elements, ensure sufficient color contrast.

Do SVG animations affect webpage performance?

Simple SVG animations have minimal performance impact. For complex animations, use CSS transforms and opacity properties, avoid frequent DOM operations.
