FastSmaller files. Cleaner paths.
No quality trade-off.
Every SVGFast result is rendered back to a bitmap and scored against the source image. Here's how it stacks up against popular tracers on a fixed set of real logos and illustrations.
5.2×
smaller output than VTracer across the test set
~98%
average rendered fidelity to the source
3.7
avg paths per file (vs 101 for VTracer)

Smaller bar = smaller SVG on a representative icon from the benchmark corpus.
Full corpus results
Six representative images across logos, illustrations and text. Fidelity is the rendered-back match to the source (higher is better); paths is the number of vector paths in the output.

Adobe rows embed a raster preview inside the SVG, so a path count isn't comparable. On the RootToRise mark VTracer edges fidelity by 0.3 points, but at 4.6× the file size and 15× the path count.
How we measure
Vector quality is easy to game with one cherry-picked image, so SVGFast scores every result the same way:
- Trace. Each tool converts the same source PNG with its default or recommended settings.
- Re-render. The output SVG is rasterized back to a bitmap at the source resolution.
- Score. That render is compared to the original to produce a fidelity score, alongside the final byte size and path count.
Numbers above come directly from the project's evaluation harness on a fixed corpus. Your results will vary with image complexity — busy photos vectorize less cleanly than logos for every tool.
