Design size (longest side)
The finished embroidery is scaled so that its longest side has this length. 100 mm fits the standard 4x4" hoop. Choose "original" if your file is already drawn at its real size.
Your file is processed instantly and deleted as soon as you download it.

What the WMF format is
In machine embroidery workflows, WMF is usually a Windows Metafile used as source artwork rather than as a finished stitch design. It stores lines, curves, fills, and text as scalable vector objects, so logos and lettering can be enlarged without the pixelation associated with raster images.
WMF files commonly come from Windows graphics programs, office software, older sign-making applications, and embroidery digitizing software during the artwork-import stage. A WMF contains visual geometry, not embroidery commands: it normally has no stitch order, stitch type, density, underlay, thread sequence, trims, or machine-specific needle movement.
What the U01 format is
U01 is a machine-embroidery stitch format associated with Barudan equipment and compatible embroidery software. It stores digitized machine instructions such as needle coordinates, color changes, and movement commands.
U01 is useful when a Barudan machine or its control software requires that format. Unlike WMF, it is intended for production and contains stitch data, but it is not generally convenient for editing shapes as vector artwork. The exact supported hoop sizes, color handling, trim commands, and machine controls depend on the U01-compatible software and machine model.
How to actually convert WMF to U01
For a quick conversion, use the converter on 101convert.com:
- Open the WMF-to-U01 conversion page on 101convert.com.
- Upload the
.wmffile. - Select
U01as the output format and start the conversion. - Download the resulting
.u01file and copy it to the machine or transfer medium required by the Barudan workflow.
If the WMF contains only artwork, use embroidery digitizing software instead of treating the operation as a purely graphical conversion. Import the file through File → Import, assign embroidery objects to the artwork, set stitch types, density, underlay, pull compensation, sewing order, trims, and thread colors, then choose the software's U01 or Barudan export command. Software support varies, so confirm that the export list explicitly includes .u01.
Before exporting, define the intended hoop size and scale. Preview the stitch simulation, check the total stitch count and color-change sequence, and save the native digitizing project separately from the exported .u01 file.
Quality and compatibility limitations
A WMF-to-U01 result can require substantial digitizing correction because vector outlines do not specify how fabric should be filled. Small lettering, narrow columns, overlapping shapes, and sharp corners are especially likely to sew poorly without manual stitch settings.
Verify the output on the target machine or in its simulator before production. U01 compatibility can vary by Barudan model, software version, hoop definition, color format, and supported commands; a file that opens correctly may still need resizing, rehooping, or removal of unsupported trims.
