Hey HN! SVG Compressor is based on SVGO, which can effectively reduce the size of SVG files. I often use inline SVG, and Tailwind CSS. If you have the same needs as me, I believe you will like it. I will continue to improve it. If you have any suggestions or you are having any problem, please do not hesitate to contact me.
I'm pretty happy with SVGOMG (https://jakearchibald.github.io/svgomg/, also using SVGO), but i rarely change most of the switches from their defaults. I think the only thing i miss about your tool is a direct markup paste instead of file upload.
