Converter
HUS to VP3 converter
Turn a HUS file (older Husqvarna Viking machines) into VP3 (Husqvarna Viking and Pfaff machines). Drop the file, VP3 is preselected, download. Runs in your browser; nothing is uploaded.
What this conversion keeps and changes
- HUS stores colours as indices into the machine's built-in palette; VP3 stores thread names, catalogue numbers and RGB values. Threads are matched to the closest entry, and the original names are kept where the target has room for them.
- Trims: HUS marks them as implicit; VP3 as explicit. They are translated, not dropped.
- Maximum stitch length is 25.5 mm in VP3, which covers everything a HUS can hold.
- VP3 has no jump command: the machine moves without stitching, and trims are written explicitly.
Inside a HUS file
- Read by: older Husqvarna Viking machines.
- Colours: colours as indices into a fixed palette, so each thread becomes the nearest palette entry.
- Trims: implicit.
- Longest stitch per record: 12.7 mm; anything longer is written as two.
- HUS is compressed; it is decoded fully in the browser.
Inside a VP3 file
- Read by: Husqvarna Viking and Pfaff machines.
- Colours: thread names and catalogue numbers alongside the colours.
- Trims: explicit.
- Longest stitch per record: 25.5 mm; anything longer is written as two.
- VP3 has no jump command: the machine moves without stitching, and trims are written explicitly.
When you need this conversion
Designs are sold and shared in the format of the digitiser's software, and HUS is common because older Husqvarna Viking machines use it. If your machine is one of the Husqvarna Viking and Pfaff models, it wants VP3. The stitches are the same; only the container changes, and the notes above are the whole list of what the container cannot carry.
Before a paid job, run the result through the pre-flight check for density and hoop fit, and read the conversion guide for the traps that are specific to each pair.
How to use it
- 1
Drop the HUS file
Drag it onto the page or click to choose it. The file is decoded on your device and drawn on a hoop grid with its size, stitch count and colour blocks.
- 2
Check the preview
Step through the sew-out order if you want to see how the machine will run it. Rotate or mirror here if the placement needs it; centring is on by default.
- 3
Download the VP3
VP3 is already selected as the output. The file is written and read back on your device before the download starts.
- 4
Copy the colours over
Open the result in the viewer to see the colours the VP3 now stores and check them against the design's colour sheet.
Questions
What changes when converting HUS to VP3?
HUS stores colours as indices into the machine's built-in palette; VP3 stores thread names, catalogue numbers and RGB values. Threads are matched to the closest entry, and the original names are kept where the target has room for them. Trims: HUS marks them as implicit; VP3 as explicit. They are translated, not dropped. Maximum stitch length is 25.5 mm in VP3, which covers everything a HUS can hold. VP3 has no jump command: the machine moves without stitching, and trims are written explicitly.
Which machines read VP3?
Husqvarna Viking and Pfaff machines. VP3 has no jump command: the machine moves without stitching, and trims are written explicitly.
Will the VP3 stitch identically?
Geometry, yes: every needle position is kept to 0.1 mm, and the writer was checked against pyembroidery. Colours, trims and stops follow what the target format can store, as described on this page.
Is the file uploaded?
No. Reading and writing happen in your browser; close the tab and nothing remains.
Can I resize it at the same time?
Not here. Scaling a stitch file changes its density; use the resize tool, which re-spaces satin, fill and running stitches, then convert the result.
