What is embroidery digitizing?
Embroidery digitizing is the process of converting artwork into a set of instructions that an embroidery machine can follow. Every stitch, every color change, every jump between sections of a design has to be mapped out precisely. The machine does not "see" your design the way you do. It reads coordinates, stitch types, and thread colors from a file, then executes them one stitch at a time.
Why you can't just send an image to a machine
A common misconception is that embroidery machines work like printers. They do not. A printer lays ink on paper in horizontal lines. An embroidery machine moves a needle through fabric in specific patterns. Fill areas need hundreds of parallel stitches. Outlines need satin columns with precise width and direction. Small text needs running stitches that follow a single path. Each of these stitch types behaves differently, and choosing the wrong one ruins the result.
This is why digitizing exists as a separate step. Someone (or something) needs to look at a design and decide: this area gets a fill stitch at 4mm density, this outline gets a 2.5mm satin column, this thin line gets a running stitch. Those decisions are what separates a clean embroidery from a tangled mess.
Manual vs. automatic digitizing
Professional digitizers have traditionally done this work by hand using desktop software. They trace shapes, assign stitch types, set underlay patterns, define pull compensation, and optimize the stitch order to minimize jumps. A single design can take 30 minutes to several hours depending on complexity. The skill ceiling is high, and good digitizers charge accordingly.
Automatic digitizing tools take a different approach. They analyze the geometry of your design and apply stitch types based on shape properties. Wide shapes get fill stitches. Narrow shapes get satin stitches. Single lines get running stitches. The best automatic tools let you override these decisions on a per-shape basis, giving you speed without sacrificing control.
Where Stitch fits in
Stitch is an automatic digitizer that works with SVG files. You upload a vector design, configure your hoop size and thread palette, and the software generates a machine-ready embroidery file. It supports DST, PES, JEF, EXP, VP3, and EMB formats, covering every major machine brand. The entire process happens in your browser with a real-time stitch preview, so you can see exactly what your machine will sew before you download.
