Why Choose Fixie?
iconizr is a powerful icon kit creator designed for comprehensive cross-browser support, including legacy browsers that don't fully support SVG. It generates both SVG and PNG sprites, provides CSS and Sass output, and includes fallback mechanisms for older browsers like IE8. For projects that must support legacy browsers, iconizr is invaluable.
However, in 2026, SVG support is universal in modern browsers (Chrome, Firefox, Safari, Edge). For modern web projects, the PNG fallbacks, Sass output, and legacy browser support add complexity that most developers don't need. The extra options increase configuration overhead.
Fixie's SVG Sprite Generator focuses on modern browsers with a streamlined interface: upload SVG icons, get an optimized sprite, and receive ready-to-use HTML/CSS code. No PNG fallbacks, no Sass configuration, no legacy browser support — just clean SVG sprites for modern web development. For legacy browser support, iconizr is the specialist. For modern SVG-only workflows, Fixie is simpler.
