About PNG files
PNG is a lossless image format with full transparency support. Transparent pixels can be treated as background without estimating where the subject ends. Lossless compression avoids JPEG-style edge noise, but gradients, tiny details, and anti-aliased edges are still simplified into stitchable colour regions.
Tip: Export logos and clip-art as PNG with a transparent background for the cleanest stitch regions.
About the SEW format
SEW (Janome SEW format) is read by older Janome and Elna machines (Memory Craft 8000/9000 era) and some Bernina models. The format stores thread colours as Janome palette indices, like JEF. Copy the file to the memory card or USB medium your machine reads.

Frequently asked questions
How do I convert a PNG to SEW?
Upload the PNG on this page — SewFlow digitizes it automatically (colour detection, background removal, stitch generation), shows a free preview, and lets you save the design to your account. Pick your size, then download the SEW file for older Janome, Elna & Bernina machines with a paid plan or bonus credit.
Does a transparent PNG background help the conversion?
Yes — transparency is the cleanest possible input. SewFlow treats transparent pixels as background automatically, so only your actual artwork is digitized, with no halo or leftover background patches.

SEW is read by older Janome and Elna machines (Memory Craft 8000/9000 era) and some Bernina models. Copy the file to the memory card or USB medium your machine reads.
Is the PNG to SEW converter free?
Converting and previewing are free, and a free account saves your designs. Downloading the finished embroidery file requires a paid plan or bonus credit.
