Open U01 embroidery files on a Mac

U01 is Barudan's format for its commercial machines. It records stitches, trims, stops and needle changes, but not thread colors.

Commonly used with: Barudan commercial embroidery machines.

What Satinsmith does with U01

Open and preview U01 files free. Save a design as U01 with any export: the free plan includes five exports a month, and paid plans are unlimited. Converting many files at once needs Studio.

  • Satinsmith shows each needle change as a color change. Because U01 stores no thread colors, choose threads from the design's source, not from the preview.

Satinsmith runs on Apple silicon Macs with macOS 14 or later. Download it free.

Check your machine's manual for the formats and versions it accepts. Satinsmith checks files in software, reports what an export changes, and does not test files on machines. Known limits.
