Found a bug? Have an idea?
SVGFast is developed in the open. Every bug report, feature request, and discussion lives on GitHub where you can track progress and weigh in.
Before you file
A great issue gets fixed faster. Please include:
- What happened vs. what you expected.
- Steps to reproduce, ideally with the source image.
- Your browser and OS version.
- A quick search to check it's not already reported.
Known limitations
These aren't bugs — they're inherent trade-offs of vectorization. Knowing them up front saves a round-trip:
Photographs don't vectorize cleanly
Continuous-tone images become large, messy files in any tracer. Keep photos as PNG, WebP, or AVIF.
Gradients are approximated
Smooth gradients are reproduced as closely as the budget allows. Flat color reproduces most faithfully.
Very large images take longer
Because everything runs locally, huge inputs use more CPU. Downscale oversized sources before converting.
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.
