Both PNG and SVG work in StitchConvert, but they behave differently during auto-tracing. Here is how to pick the right format.
SVG stores shapes as paths, not pixels. Logos, monograms, and flat artwork exported from Illustrator, Inkscape, or Canva usually trace cleanly because edges stay sharp at any size.
If your design uses solid fills and a limited color palette, start with SVG. You will spend less time fixing jagged edges after upload.
PNG is a good choice when you only have a raster export or a screenshot of a simple design with high contrast and large shapes.
Avoid tiny text, gradients, and photo-realistic detail in PNG files. Auto-tracing treats each color region as a fill area, so soft blends become noisy stitch regions.
Logo or text-heavy art: export SVG if you can. Simple icon or single-color mark: PNG at least 800 px on the longest side is usually fine.
Either way, map your thread colors in StitchConvert and preview stitches before paying so you know the result matches your hoop and machine.
