Stitch Toolbox, embroidery files in the browser

Field notes

The toolkit exposes stitch-by-stitch previews, color blocks, thread names, run time, thread use, and hoop fit directly in the browser. Its diagnostics use concrete thresholds, including stitches under 0.3 mm and jumps over 12 mm, while the converter lists 22 formats and 11 output formats. The page also describes a validation process involving 226 files from named embroidery software ecosystems and read-back checks against two readers.
