Convert PEC to EXP 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 EXP

   Open the Stitchist converter and choose EXP 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 .exp 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 EXP

The standalone EXP copy does not preserve a self-contained PEC palette. Supply a chart, and check whether the receiving workflow requires files in addition to EXP. Keep the PEC source for future conversions.

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 EXP result

EXP stores an embroidery stitch sequence. It is used in Melco workflows and by some BERNINA machines, but the surrounding files expected by a particular machine can differ. Stitchist's converter downloads a single EXP stitch file.

Some BERNINA workflows use additional color or preview companion files. This converter does not create a BERNINA USB bundle, so check your machine manual before relying on a lone EXP.

A standalone EXP does not carry RGB thread colors in this workflow. The preview uses sample colors; retain your reference image and thread sequence.

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.

• When a shop asks for EXP, confirm whether it wants only the stitch file or a package with companion files. Keep any original companion files with the original design.
• 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.
