Welcome to OneSVG Studio
A free suite for converting PNG/JPG/WebP images to high-quality pure SVG. VTracer for color, Potrace for mono logos, SVGO for optimization. No signup, no watermark.
Pick your tool
Four specialized engines, one ecosystem.
Color Vectorize (VTracer)
Convert color PNG/JPG to pure SVG with the VTracer algorithm — preserves gradients and fine detail.
Mono Vectorize (Potrace)
Vectorize logos, icons, and black-and-white line art with Potrace — smooth curves, clean paths, minimal size.
SVG Optimizer (SVGO)
Shrink existing SVG files by up to 70% with zero visual loss: strip metadata, round coordinates, merge paths.
Batch Convert
Upload many images at once, pick a single engine (color or mono), download them all as a ZIP of SVGs.

Free online raster-to-pure-SVG toolkit
OneSVG Studio is a focused suite of four tools that convert raster images (PNG, JPG, WebP, GIF, BMP) to pure SVG — meaning files with actual <path> elements, not raster images embedded in <image> tags. Perfect for UI design, large-format printing, animation, and infinitely scalable logos.
Under the hood we use VTracer (Rust) for color and Potrace for black-and-white — the two leading open-source tracers. After tracing, each SVG is automatically optimized with SVGO: strip Inkscape metadata, round coordinates, merge duplicate paths. Everything runs on our own server (Intel i5, 8GB RAM, BullMQ queue) so your machine stays free.
Every uploaded file is deleted immediately after the result is produced. No logging of image content, no third-party sharing, no watermarks. 100% free — there's just a 30/hour/IP rate limit to prevent abuse.
