Building on top of it, some modifications were made to it using Inkscape.
The we cleaned it using svgo tool. It reduced file size by around 50%.
$ svgo -i elegant_logo.svg --pretty elegant_logo.svg: Done in 80 ms! 8.029 KiB - 52.5% = 3.815 KiB
Then, we converted SVG to PNG using svgexport.
$ svgexport elegant_logo.svg elegant_logo.png 100%
The resultant file was around 1MB is size. So we optimized it using ImageOptim, which reduced the file size by 98%.
Your can download the files from our Git repository.
