PNG to SVG Tracer

The PNG to SVG Converter traces raster PNG images into vector SVG format. Vector images scale without pixelation, look sharp at any size, and have smaller file sizes for simple graphics. Best for logos, icons, simple illustrations, and high-contrast graphics. Not suitable for photographs or complex detailed images — tracing those produces massive vector files that don\u2019t look better than the original.

Upload a PNG and choose tracing parameters (color quantization, threshold, curve smoothing). The tool runs edge detection and path fitting to produce an SVG approximation of the original. Preview compares original vs. vector. Export the SVG for use anywhere (web, print, editing in Illustrator/Inkscape). All processing runs in your browser.

Raster-to-vector conversion is called image tracing or vectorization. The tool uses algorithms similar to Potrace or Autotrace.

Process:
1. Preprocessing: optionally reduce colors (posterize), increase contrast
2. Threshold: convert to binary (black and white) or limited color palette
3. Edge detection: find boundaries between regions
4. Path tracing: follow edges to create curves
5. Curve fitting: convert point sequences into Bezier curves
6. Simplification: reduce curve complexity while preserving shape
7. SVG generation: output paths with fill colors

Quality depends heavily on input:
- High-contrast simple images (logos, icons): excellent, clean vectorization
- Mid-complexity (simple illustrations): decent, may need manual cleanup
- Photos: very poor — produces huge files with jagged edges, not usable
- Gradients and fine details: lost in tracing

Tracing modes:
- Black and white: single color, simplest, fastest
- Limited palette (5-10 colors): posterize first, then trace each color layer
- Full color: traces many color boundaries, very complex output

Parameters:
- Threshold (black/white): pixel brightness cutoff for binarization (0-255)
- Color count: how many colors to reduce to for color tracing
- Curve tolerance: how closely curves match original (lower = more accurate, more nodes)
- Smoothing: corner detection and rounding

For best results:
- Use high-resolution source (2000+ pixels on long side)
- Solid colors, not gradients
- Clean edges, not anti-aliased
- Simple shapes, not complex detail

Common uses:
- Convert raster logo to vector for scalable use
- Create SVG icons from PNG designs
- Prepare graphics for cutting machines (CNC, laser) that need vector input

Limitations:
- Photos and complex images: not suitable
- Text in images: traced as shapes, not editable text
- Gradients lost: converted to solid fills
- Anti-aliased edges: stairstep effect in output

For photos, alternative approaches include rendering raster image at higher resolution (upscaling) rather than vectorizing. True photo-to-vector conversion is computationally expensive and produces massive files.

Performance: tracing takes seconds to minutes depending on image size and parameters.

Compared to Adobe Illustrator\u2019s Image Trace, this tool is free. Illustrator has more refined tracing algorithms; this tool covers the common case.

Compared to online tracing services like Vectorizer.ai, this tool runs in browser. Paid services offer higher quality tracing powered by AI; this tool is free and private.

Compared to command-line Potrace, this tool has a browser UI. Potrace is the industry-standard tracing engine; this tool uses similar algorithms with visual interface.
