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.

Add a folder with your U01 files to the free Satinsmith library to preview them before you rely on a workflow. The library lesson shows the steps with practice files.
Before you sew
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.
