Open a KSM file. See every stitch.

A legacy machine format that stores needle-change commands. Preview the design before loading it onto a machine. The viewer parses the real stitch data and reports the design size, thread sequence, jumps, trims, and colour stops.

Real KSM parsing

The server reads the machine-file structure and stitch commands. Renaming another file to .ksm is rejected.

Production metrics

Check dimensions, stitch count, thread count, jumps, trims, colour changes, and the final end command.

Short-lived processing

Viewer uploads are streamed to the restricted engine and are not added to conversion history or free-job usage.

KSM compatibility: KSM uses needle-change commands and cannot preserve full thread-colour metadata.
