How Image-to-SVG Conversion Works

Our Image-to-SVG converter uses VTracer, a powerful WebAssembly-based vectorization engine that runs directly in your browser. Unlike server-side solutions, this provides instant feedback and complete privacy for your images.

The VTracer Process

1

Image Analysis

VTracer analyzes your image pixel by pixel, identifying colors, edges, and shapes.

2

Color Clustering

Similar colors are grouped together based on your clustering mode and precision settings.

3

Path Tracing

Edges are traced and converted to mathematical curves and paths using your path mode settings.

4

SVG Generation

Clean, optimized SVG code is generated with proper layer organization and structure.

Getting Started with Image Conversion

Step-by-Step Process

1. Generate or Upload Image

Start by generating an image from a text prompt, or use the dedicated Image-to-SVG page to upload your own image.

2. Access SVG Settings

After generation, click the "SVG Settings" tab to access VTracer configuration options.

3. Adjust Parameters

Fine-tune the conversion settings based on your image type and desired output quality.

4. Apply & Download

Click "Apply Settings" to regenerate the SVG, then download your optimized vector graphic.

Basic Parameters Explained

The basic parameters control the fundamental aspects of your conversion. These settings have the most impact on your final result.

Clustering Mode

Determines how colors are grouped during conversion. This is one of the most important settings.

Binary Mode

Converts images to black and white only. Perfect for:

  • • Line drawings and sketches
  • • Text and documents
  • • Simple logos with high contrast
  • • Silhouettes and stencils

Color Mode

Preserves full color information. Ideal for:

  • • Colorful illustrations
  • • Photographs
  • • Complex artwork
  • • Brand logos with multiple colors
Pro Tip

Start with Color mode for most images. Switch to Binary if you want a simplified, high-contrast result.

Layer Structure

Controls how SVG layers are organized and how shapes interact with each other.

Stacked

Layers are placed on top of each other. Best for:

  • • Most photographs and illustrations
  • • Images with overlapping elements
  • • Complex compositions
  • • When you want to edit layers separately

Cutout

Inner shapes cut holes in outer shapes. Perfect for:

  • • Logos with negative space
  • • Icons with holes or cutouts
  • • Stencil-style designs
  • • Minimalist graphics

Color Precision (1-8)

Controls the number of colors in the final SVG. Higher values preserve more colors but increase file size.

1-2: Simple
3-4: Balanced
5-6: Detailed
7-8: Maximum

Lower Values (1-3)

  • • Smaller file sizes
  • • Faster processing
  • • Simplified color palette
  • • Good for logos and icons

Higher Values (6-8)

  • • More color accuracy
  • • Larger file sizes
  • • Better for photographs
  • • Preserves gradients

Noise Reduction (0-20)

Removes small artifacts and noise from the image. Higher values remove more noise but may lose fine details.

0-5: Minimal

Keeps most details, some noise may remain

6-12: Balanced

Good balance between detail and cleanliness

13-20: Aggressive

Very clean result, may lose fine details

Important

Start with lower values (4-8) and increase gradually. High values can remove important details.

Advanced Parameters

These advanced settings give you fine-grained control over the conversion process. Adjust these after you're comfortable with the basic parameters.

Path Mode

Determines how paths are represented in the SVG. This affects both appearance and file size.

Spline

Smooth curves using Bézier paths

  • • Best for organic shapes
  • • Smooth, flowing lines
  • • Smaller file sizes
  • • Default recommendation

Polygon

Straight line segments only

  • • Sharp, angular shapes
  • • Good for geometric designs
  • • Larger file sizes
  • • More precise edges

None

No path optimization

  • • Raw pixel data
  • • Largest file sizes
  • • Most accurate to original
  • • Rarely recommended

Layer Difference (1-255)

Controls the color difference threshold for creating new layers. This directly affects how many layers your SVG will have.

Layer Count Impact
1-50
Many layers
51-100
Balanced
101-255
Few layers

Lower Values (1-50)

  • • More layers created
  • • Better color separation
  • • Larger file sizes
  • • More editing flexibility

Higher Values (100-255)

  • • Fewer layers created
  • • Colors merged together
  • • Smaller file sizes
  • • Simpler structure

Corner Threshold (0-180°)

Controls the angle threshold for detecting corners. This affects how smooth or sharp your paths will be.

Lower Values (0-60°)

Detects more corners, creates sharper paths

  • • Sharp, angular results
  • • Good for geometric shapes
  • • More path points
  • • Larger file sizes

Higher Values (90-180°)

Fewer corners detected, smoother curves

  • • Smooth, flowing results
  • • Good for organic shapes
  • • Fewer path points
  • • Smaller file sizes

Length Threshold (0-20)

Minimum path length to keep. Shorter paths are removed to simplify the SVG and reduce file size.

Recommended Values by Image Type

0-2
Detailed images, keep small elements
3-8
Balanced cleanup, most images
9-20
Aggressive cleanup, simple shapes

Path Precision (1-16)

Controls the precision of path coordinates. Higher values create more precise paths but increase file size.

Lower Precision (1-4)

  • • Faster processing
  • • Smaller file sizes
  • • Slightly less accurate
  • • Good for web use

Higher Precision (8-16)

  • • More accurate paths
  • • Larger file sizes
  • • Better for print
  • • Professional quality

Max Iterations (1-50)

Maximum number of optimization iterations. Higher values produce better quality but take longer to process.

1-10
Fast processing
11-25
Balanced quality
26-50
Maximum quality
