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
Web Icons
Website navigation icons, social media icons, function button icons, etc.
Logo Design
Corporate logos, brand logos, product identifiers and other vector graphics
Data Visualization
Charts, graphs, infographics and other data displays
Illustration Design
Simple illustrations, decorative patterns, background graphics, etc.
User Interface
Mobile app interfaces, web UI elements, interactive components

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.
