Scalable Vector Graphics (.svg)
W3C StandarScalable Vector Graphics (SVG) is an XML-based vector image format for two-dimensional graphics with support for interactivity, CSS styling, and animation.

Matriks Perbandingan Teknis: SVG vs Pesaing
| Atribut Teknis | SVG (Saat Ini) | HTML5 Canvas | PNG | |
|---|---|---|---|---|
| Rendering Model | Retained mode vector DOM | Immediate mode bitmap canvas | Retained mode fixed page container | Raster pixel grid |
| Styling & CSS | Fully styleable via CSS classes and variables | Requires JavaScript canvas API redraws | No dynamic CSS styling | Fixed raster pixels |
| Infinite Scalability | Yes (mathematical vector curves) | Requires manual resolution scaling | Yes (vector elements) | No (pixelates when enlarged) |
| Interactivity | Native DOM events (hover, click, animations) | Requires manual hit detection math | Static document | Requires image map or canvas |
Mode Kerusakan Umum & Panduan Pemulihan Hex
⚠️ Browser displays XML Parsing Error: unclosed token or mismatched tag.
Penyebab Utama: Malformed XML syntax, missing closing tags, or unescaped ampersands ('&' instead of '&').
Pemulihan: Validate with an XML linter (xmllint file.svg) and correct unbalanced tags.
Analisis Keamanan & Vektor Serangan Parser
Because SVG is executable XML that supports '<script>' tags and external entities, it presents significant XSS and SSRF risks if untrusted SVGs are displayed.
Vektor Serangan yang Diketahui
- Stored Cross-Site Scripting (XSS) via embedded '<script>' tags or 'onload=' event handlers.
- XML External Entity (XXE) attacks reading local server files when parsed on backend servers.
- Billion Laughs XML entity expansion causing denial of service.
Praktik Terbaik Defensif: Always sanitize SVGs using DOMPurify before embedding, or serve SVGs with 'Content-Security-Policy: default-src 'none'' or as '<img>' tags which automatically disable scripts.
Asal-Usul & Tonggak Sejarah
Keunggulan & Kelebihan Utama
- Infinite resolution independence: crisp lines and typography on any display or print scale.
- Extremely small file size for logos, icons, and UI interface elements.
- Fully scriptable and styleable via CSS and JavaScript inside the browser DOM.
Keterbatasan Teknis & Kekurangan
- Unsuitable for photographs or complex continuous-tone imagery.
- Complex vector paths with thousands of nodes can cause CPU rendering lag and high battery drain.
- XML nature allows embedded scripting, requiring strict sanitization before rendering untrusted uploads.
Fakta Teknis Menarik
- Because SVG is plain XML text, compressing it with Gzip (producing an .svgz file) often reduces size by 70%–80%.
- The viewBox attribute defines an abstract coordinate canvas that maps dynamically to physical screen pixels.
Pertanyaan Teknis yang Sering Diajukan
Can SVG files contain malicious code?
Yes. Because SVG is valid XML, it can contain embedded JavaScript ('<script>') that executes if the SVG is loaded directly in a browser or opened in an inline '<svg>' element. Serving SVGs via an '<img>' tag automatically neutralizes script execution.
When should I use SVG instead of PNG?
Use SVG for icons, logos, charts, illustrations, and typography where crisp scaling across all screen sizes and small file sizes are required. Use PNG or WebP for photographs.
