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.

Frequently asked questions

What is "pure SVG" and how is it different?
A pure SVG only contains real vector primitives (<path>, <polygon>, <circle>, <rect>). A fake SVG wraps a raster image in an <image> tag — zoom and it pixelates. Every file OneSVG produces is pure SVG.
When should I pick Color vs Mono?
Use Color for illustrations and photos. Use Mono for single-color logos, icons, handwriting, or line art — the paths are smoother and the file is lighter.
Why is my output SVG heavier than the original?
VTracer optimizes for quality; detailed photos can produce 500KB-2MB SVGs. Lower Color Precision (6→4) or raise Filter Speckle (4→8) to reduce noise-driven detail. For photos, sometimes keeping PNG is best unless you need scalability.
What's the size limit?
25MB per file for single convert, up to 20 files × 25MB for batch. Images above 2048px are automatically resized (aspect preserved) to avoid OOMs.
Are my files stored?
No. Originals are deleted the moment the worker finishes tracing. Output SVGs live for one hour so you can download them, then a cleanup job removes them. No backups, no content logs.
Can I use the output commercially?
Yes — the output is yours. OneSVG is just a processor and claims no rights. (Usual caveats apply for inputs you don't own, such as stock or copyrighted images.)
Is there an API?
V1 is web-UI focused. Internal endpoints exist (/api/upload, /api/optimize) but are undocumented and rate-limited. Contact us via the feedback widget if you need integration.
