SewFlow converts PNG, JPEG, SVG, BMP, GIF, WebP, and TIFF images into SEW embroidery files for older Janome and Elna machines. The converter detects colours, builds dense satin-stitch fills, and writes the SEW stitch stream automatically.
How the Conversion Works
- •Colour detection groups your image into a small set of thread layers.
- •Each colour is matched to the nearest Janome thread-chart entry.
- •Each layer is filled with stitch paths at an embroidery-friendly density.
- •Layers are ordered and separated with colour-change stops, then exported as a SEW file.

Photos with soft gradients or hundreds of colours don't translate to thread. Flatten to bold shapes and a few solid colours for the cleanest SEW result.
