Raster vs Vector: Understanding the Difference
Raster images (PNG, JPG) are grids of colored pixels. Zoom in far enough and you see individual squares. Vector images (SVG) are mathematical descriptions of shapes and curves. They scale infinitely without losing quality.
Converting raster to vector involves 'tracing' — analyzing the pixel image and creating vector shapes that approximate its appearance. This works well for some images and poorly for others.
When Vectorization Works Well
Simple graphics with distinct shapes and limited colors convert excellently. Logos, icons, line art, text, and illustrations with flat colors produce clean vector results that scale perfectly.
The traced SVG can be edited in vector software like Illustrator or Inkscape, with individual shapes selectable and modifiable.
Limitations with Photographs
Photographs do not convert well to vectors. The subtle gradients, textures, and millions of colors in photos cannot be represented as simple vector shapes. The result looks artistic but heavily stylized — useful for effects but not for preserving photo realism.
For photos needing larger sizes, consider AI upscaling rather than vectorization.
Trace Images Privately
FormatWiz traces your PNG images entirely in your browser using JavaScript-based vectorization algorithms. Your graphics never upload to external servers.
This is important for logos, brand assets, and other graphics that should remain confidential during processing.
