convert jpg to svg
A JPG carries compression blotches around letters and shapes, and tracing tries to turn all of that into drawing. Two settings fix most of it: smoothing and background color removal.
The limit is 20 + 12 x smoothing.
The radius never goes above 5.
5 + 4 + 2 = 11, well under 96, so the layer is removed.
15 + 25 + 55 = 95, one below the limit, so the layer is removed.
20 + 30 + 60 = 110, above 96, so the layer stays.
Upload the image, pick the type (Logo works for most cases) and download the SVG. The conversion is a trace: the tool reduces the colors, follows the outline of every region and writes shapes instead of pixels. It is not just wrapping the PNG inside an SVG file, which would still be a picture made of pixels.
Almost always compression. Raise Smoothing to 2 or 3, lower Colors to the real number of colors in the drawing and lower Detail so small blotches are filtered out. If the image is very small and heavily compressed, no setting replaces a better version of the file.
The tool only removes it when the most common border color covers at least half of the border and a palette color is within 96 of it. A photo with a varied border, a gradient background or shadows touching the edge do not pass that rule. In those cases a notice appears and nothing is removed.
Only for the poster effect. A photo needs many layers to look natural, and the resulting file is usually larger than the JPG. Tracing pays off on flat art: logos, icons, stamps and drawings.
Tracing works best on logos, icons and flat art. Photos turn into a posterized version, like a poster print.
