Bug report

Something isn't working the way it should.

Feature request

An idea to make SVGFast better.

Known limitations

These aren't bugs — they're inherent trade-offs of vectorization. Knowing them up front saves a round-trip:

By design

Photographs don't vectorize cleanly

Continuous-tone images become large, messy files in any tracer. Keep photos as PNG, WebP, or AVIF.

By design

Gradients are approximated

Smooth gradients are reproduced as closely as the budget allows. Flat color reproduces most faithfully.

Tip

Very large images take longer

Because everything runs locally, huge inputs use more CPU. Downscale oversized sources before converting.

Tip

Tiny embedded text is better re-typeset

Trace large lettering fine; for small text, set it with a real font for sharper, smaller results.

Hitting something not on this list? That might be a real bug — let us know.
