Frequently Asked Questions

      
Everything you need to know about SVG backgrounds.

      


        

          
What is an SVG background?

          

            
An SVG background is a vector graphic used as a website or app background. Because SVG is resolution-independent it looks sharp at any screen size — from mobile to 4K displays. You can embed it inline in your HTML, reference it via a CSS background-image, or export it as a standalone file.

          

        


        

          
How does the seed system work?

          

            
The seed is a number fed into a deterministic pseudo-random number generator (Mulberry32). The same seed always produces identical output — every point, every curve, every gradient position. This means you can save, share and reproduce any design simply by storing the seed along with the other settings.

          

        


        

          
Can I use these in production?

          

            
Yes. All generated SVGs are pure SVG markup with no external dependencies, no scripts, and no licensing restrictions. You can use them freely in personal and commercial projects. The SVG export is a clean, self-contained file you can host anywhere.

          

        


        

          
What is the difference between SVG and PNG export?

          

            
The SVG export is a scalable vector file — infinitely sharp and typically smaller in file size. The PNG export is a raster bitmap rendered at your chosen resolution (default 1920×1080). Use SVG for web backgrounds; use PNG when the target environment does not support SVG (e.g. some email clients or design tools).

          

        


        

          
How do I use the CSS data URI?

          

            
Switch the output tab to CSS. The generated code embeds the SVG directly in the background-image property as a percent-encoded data URI. Paste it into your stylesheet and it will render without any additional file references or network requests — ideal for critical above-the-fold styles.
