PNG to VP3 converter

An embroidery machine cannot read a picture. It reads a list of needle positions — where to stab, in what order, in which colour. Turning artwork into that list is called digitizing, and it is normally done by hand in software costing hundreds or thousands.

This converter runs Stitchist's auto-digitizer on your image. It reduces the artwork to a workable palette, traces each colour region into a clean outline, decides whether each region should be a filled area or a satin column, works out the stitch angle, sequences the regions so the machine changes thread as little as possible, and adds the underlay and pull compensation that stop the design puckering.

Flat artwork with clear areas of colour converts best: logos, lettering, line art, simple illustrations. Photographs do not — there is no such thing as a photographic stitch, and any tool promising one is guessing.

PNG is the better starting point of the two common ones. It stores exact pixels, so edges stay crisp and the tracer sees the colour you actually drew. It also supports transparency, and a transparent background is dropped rather than digitized as a coloured field.

VP3 is the Husqvarna Viking and Pfaff format, and holds both the stitches and the design's thread information in one file.

The VP3 written here is a real machine file for Husqvarna Viking and Pfaff machines. As with any digitized design, test-stitch on scrap with the same stabilizer before you commit to the final piece.
