HUS Embroidery File Format

HUS is the legacy native format for older Husqvarna Viking embroidery machines. It stores stitch data along with thread color references from the Husqvarna palette — a key difference from purely stitch-only formats like DST.

Working with HUS files

01

Color data included

HUS files embed thread color references from the Husqvarna Viking palette, unlike DST or EXP. This makes thread setup easier but can cause color shifts when converting to other formats.

02

Legacy machine support

Designed for older Husqvarna Viking models including the Designer, Rose, and Orchidea series. Newer Husqvarna Viking and Pfaff machines use the modern VP3 format instead.

03

Convert any image

Upload a PNG, JPG, SVG, or WebP file and StitchPilot.ai will digitize it to HUS format using AI-assisted stitch planning for your legacy machine.

04

Free online viewer

Preview HUS files in the browser — no software needed. Inspect stitch paths and color stops before loading the design onto your machine.

HUS vs VP3

Choosing the right format

If your machine supports VP3, always prefer it over HUS — VP3 offers richer stitch types, larger design areas, and better software support. HUS is only needed for older legacy machines.

  • VP3 is the modern Husqvarna Viking format with richer features
  • HUS lacks advanced stitch type support found in VP3
  • HUS color data may shift during conversion to non-Husqvarna formats
  • Use the StitchPilot.ai viewer to verify colors before stitching
