1. What is a PES file?
PES is the native embroidery file format of Brother embroidery machines and Brother software such as PE Design. It contains information about stitching sequence, colors, stitches, and patterns.
2. Why is the PES file not recognized?
There are different versions of the PES format – the current version is 11. Older versions of PE-Design (e.g., PE-Design 8 or 10) cannot read PES files created with a newer version (e.g., V11).
Example: A file saved with PE-Design 11 cannot be opened with PE-Design 8.

3. How do I find out the version of my PES file?
The PES version is stored in the file itself, but isn't directly visible without additional software. Programs like Wilcom Truesizer , Embrilliance , or Creativate often display the internal version.
4. What can I do if my software doesn't open the file?
Solution 1: Update PE design
If you're using PE Design, check if you can upgrade to a newer version. Only recent versions like PE Design 11 support the latest PES files.
Solution 2: Use compatible software
Some embroidery software (e.g., Creativate, Bernina V9, Wilcom, Hatch) allows you to save in different PES versions. Ask the person who created your file to save it in an older PES version (e.g., version 6 or 8).
Solution 3: Use alternative formats
Ask for an additional export file, such as .DST or .EXP format, if your program supports these formats.
5. Is there a way to convert PES files?
Yes. You can convert PES files to other versions using special software. These include:
- Embrilliance Essentials
- Creativate from PFAFF, Singer, Husqvarna VIKING
- Wilcom Hatch
A free solution is currently not reliably available.

Conclusion
If a PES file can't be opened in PE Design, it's usually because the file version is too new. Upgrading the software or using compatible programs can solve the problem.
