Symbl
Test logo scalability, legibility, and real-world mockups in real time
Symbl is a web-based testing tool for logo marks and brand symbols. Upload an SVG or PNG to instantly preview how it looks across various contexts—such as favicons, app icons, embroidery, and billboards—while receiving an automated analysis on edge density, fill ratio, and legibility at small sizes.
What it's for
- Check how a logo mark scales down to tiny favicon or app icon sizes
- Preview branding across physical and digital mockups like embroidery, badges, and billboards
- Identify overly complex details or thin strokes that hurt legibility
Features
- Drag-and-drop support for SVG and PNG logo files
- Multi-scale previews ranging from 16px favicons to large outdoor signage
- Automated scalability and legibility score out of 10
- Visual analysis metrics including edge density and fill ratio
