About PolySVG
PolySVG is our in-house SVG editor and a free all-in-one vector platform. The name comes from Poly (polygon) + SVG (Scalable Vector Graphics). Our goal is simple: let everyone turn a bitmap into a vector, edit vectors and get vector assets without any barrier.
What we do
- Image to SVG: an in-house vectorization model (color quantization → contour tracing → Bézier fitting) with five modes for photos, icons, logos, line art and outlines;
- Online vector editing: background removal, painting with the brush, erasing and path-level recoloring, with no design software to install;
- Free vector gallery: SVG assets across ten categories, free to download, free for commercial use and editable online.
Technology
The site is built with Next.js, stores its data in MySQL and Redis, and keeps all images and attachments in server-side object storage, distributed worldwide through file.polysvg.com. The vectorization model is developed in house; its core algorithms follow classic computational geometry methods (K-Means, Marching Squares, RDP, Catmull-Rom), with extensive engineering work to make them fast in the browser.
