Free Online PNG to SVG Vector Converter
Trace raster PNG, JPG, and WebP graphics into scalable SVG paths using boundary contour tracing.
Understanding Bitmap Vectorization
Raster images (such as PNG and JPG) map visuals onto a static grid of pixels. When scaled up on higher-density screens or large print canvases, bitmaps reveal jagged edges and blurriness.
In contrast, Scalable Vector Graphics (SVG) describe graphics as mathematical coordinate paths, curves, and polygons. This tool computes contrast contours across your image matrix and builds interconnected vector <path> commands that scale cleanly to any resolution.
Raster vs. True Vector Graphics
| Metric | Bitmap Graphics (PNG, JPG) | Vector Graphics (SVG) |
|---|---|---|
| Internal Structure | Static pixel grid coordinates | Mathematical path geometries (XML) |
| Scalability | Degrades when enlarged | Infinite scalability without degradation |
| Styling Flexibility | Fixed pixel colors | CSS controllable (fill, stroke, animations) |
| Ideal Subject Matter | Photographs with complex textures | Logos, glyphs, badges, and typography |
How to Convert Bitmaps to Clean SVG
- Select Source Graphic: Upload a high-contrast logo, symbol, or badge with a clean or transparent background.
- Calibrate Luminance Threshold: Adjust the threshold slider until the preview accurately isolates the subject contours without noise.
- Select Fill Color: Pick an initial fill palette for the generated vector path.
- Export or Copy: Download the production-ready
.svgfile or copy the raw XML markup directly into your HTML/CSS pipeline.
Technical Limitations & Best Practices
- Photographs Are Inefficient as Vectors: Photographs contain millions of minute tonal shifts. Tracing a photo creates tens of thousands of complex path coordinates, producing an unmanageably heavy SVG file.
- High Contrast Yields Better Results: Clear separation between dark subject matter and bright or transparent backgrounds produces cleaner boundary paths.
- Client-Side Processing Scale: Large files are constrained to optimal dimension thresholds to ensure browser thread responsiveness without memory freezes.

Frequently Asked Questions
How does in-browser vectorization work?
The tool parses the bitmap onto an offscreen canvas, extracts brightness contours using luminance thresholding, and tracks boundary loops to construct true scalable SVG <path> elements.
Are my images uploaded to any remote server?
No. All canvas rendering, contour tracing, and SVG generation occur entirely inside your browser's JavaScript engine. No file data leaves your device.
Can I convert complex color photos into clean vectors?
Vectorization works best for logos, icons, line art, and high-contrast shapes. Complex photographic images contain millions of soft gradients that result in massive, impractical SVG files.
Can I edit the generated SVG in Illustrator or Figma?
Yes. The generated file is standard W3C-compliant SVG markup using vector path geometry, allowing full editing in software like Adobe Illustrator, Figma, and Inkscape.
