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.

Why OneSVG

Fully private

Files are deleted immediately after processing.

No install

Open browser, use, done. No account, no software.

100% free

All core features free, no daily limits.

Pure SVG quality

Real vector paths — no embedded raster, scales cleanly.

Pure SVG — what 90% of free converters get wrong

Not every .svg file is actually vector. Open it in a text editor: if you see data:image/png;base64 or data:image/jpeg;base64, that's just a raster image wrapped in an .svg shell. OneSVG always outputs pure SVG — real <path>, <polygon>, <circle> primitives.

Fake SVG (most free converters)

<svg>
  <image xlink:href="data:image/png;base64,
    iVBORw0KGgoAAAANSUhEUg..." />
</svg>

A raster image wrapped in a .svg shell
Zoom 300% and it pixelates
Can't edit paths in Illustrator/Figma
File 1-5 MB — heavier than the source PNG
Can't animate with CSS or GSAP

Pure SVG (OneSVG always)

<svg viewBox="0 0 100 100">
  <path d="M12 2L2 22h20z" fill="#e11"/>
  <circle cx="50" cy="50" r="20"/>
</svg>

Real vector paths — mathematical curves
Infinite zoom, always sharp
Edit every anchor point in AI/Figma
File 2-500 KB — much lighter
Animate path, morph, draw-on effects

Quick test: download an SVG from any converter and open it in Notepad or VSCode. If you see 'base64' — it's a fake. If you see 'M10 10L20 20' or 'd=' — it's a pure SVG.

3 steps to a high-quality pure SVG

1
Pick the right tool
Full-color images and illustrations → Color Vectorize (VTracer). Black-and-white logos and icons → Mono Vectorize (Potrace). Existing SVG you want to shrink → SVG Optimizer. Many images at once → Batch Convert.
2
Upload and tweak
Drag-drop your PNG/JPG/WebP. Adjust preset, threshold, color precision, or filter speckle as needed. Anything over 2048px is auto-resized to avoid memory issues.
3
Download your pure SVG
Output is real vector paths — drop it into the web, print at A0, animate with CSS/GSAP, send to a laser cutter. SVGO multipass is applied automatically so the file is as light as it can be.

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.

Why is OneSVG completely free?

OneSVG runs on our own homeserver at Phần Mềm Tổng Hợp — operating costs are low enough to absorb community traffic. No intrusive ads, no data collection, no selling of user profiles.

Is my data used to train AI models?

No. Uploads are deleted within 1 hour, we don't log image content, and nothing is ever used to train any model.

Can the exported SVG be edited in Illustrator or Figma?

Yes, 100%. Because the output is a pure path-based SVG, Adobe Illustrator, Inkscape, Figma, and Affinity Designer all open it and let you edit every anchor point, every path, and every fill color.
