Convert PEC to U01 online

Step by step

1. Start with the original file

   Choose the .pec embroidery file. Extract it first if it is in a ZIP. Keep the original extension; changing a filename is not conversion.

2. Select U01

   Open the Stitchist converter and choose U01 in the output selector. The link on this page selects it for you. Upload the file, then click Convert.

3. Inspect the converted result

   Compare the displayed width, height, stitch count and color sequence. The preview is read from the written output, not just copied from the input.

4. Download and check at the machine

   Sign in or create a free account to download the .u01 file. Save it promptly: temporary results normally expire after 30 minutes and can disappear sooner after a restart. Check the file in your machine's workflow before sewing.

When to convert PEC to U01

For a PEC-to-Barudan handoff, give the operator the original color list and design dimensions. A domestic file's palette should not be confused with the physical needle assignments on a multi-needle machine.

What your PEC file contains

PEC is a Brother-family stitch format, also used within PES files. Some machines and software accept standalone PEC, but PES is often the more familiar delivery choice. Use PEC when the recipient or machine specifically supports it.

PEC uses a limited thread palette. Approximate color matches can appear even when the stitch positions and color-change order are correct.

What to check in the U01 result

U01 is associated with Barudan stitch-file workflows. A U01 delivery file is a machine sequence, not the original object-based digitizing document. Confirm the accepted file format and needle setup with the receiving operator.

Review needle changes, machine stops and the receiving Barudan model's requirements. Keep a written color sequence so the operator can assign the intended threads.

U01 does not preserve RGB thread colors in this converter. Sample preview colors are not a thread shopping list; check needle assignments and the original chart.

What changes, and what does not

Stitchist converts the decoded stitch sequence. The destination format may round coordinates, split a long stitch into smaller movements, or encode trims and stops differently. A slightly different stitch count is not by itself proof of a damaged design.

The converter does not resize the design, regenerate a fill, repair weak digitizing or restore object editing. Compare dimensions and sewing order, and keep the original file as your reference.

• For a commercial handoff, include the final dimensions and a numbered thread sequence with the U01. A format name alone does not describe the sewing setup.
• Use the machine manual to confirm format, version and embroidery-area support.
• For a design you plan to sell or repeat, test the final size on the intended fabric and stabilizer.

If the file is rejected

The input must be an embroidery file, not a PNG, JPEG, PDF or ZIP renamed to .pec. Use Auto Digitize for artwork. If a valid original file is not recognized, provide its original format when asked or re-export it from the source software. The stitch-file upload limit is 10 MiB.

Do not cycle through unrelated source-format hints. That can decode the wrong bytes without producing a trustworthy design.
