Free online PS to EXP converter

What the PS format is

In machine embroidery, PS identifies a design format used by particular embroidery software or machine ecosystems; it does not have one universally implemented specification like a standard interchange format. PS files can contain stitch coordinates, color-change information, design dimensions, and other digitizing data, depending on the program that created them.

You may encounter design.ps files in legacy design collections, proprietary digitizing applications, or downloads supplied for a specific embroidery system. The extension alone is not enough to identify the exact PS variant, so the originating software and the file's design preview are useful when a converter reports that the file is unsupported.

What the EXP format is

EXP is an expanded stitch format associated primarily with Melco embroidery machines and software. It stores the needle-movement instructions needed to sew a design and is supported by many embroidery editors and machine-format converters.

EXP is useful when a Melco-compatible workflow requires a compact stitch file rather than the original digitizing project's editable format. It is less suitable for later design editing because it generally does not retain objects, outlines, fills, lettering, or the full set of digitizing settings from the source.

How to convert PS to EXP

1. Make a backup of the original file, then confirm that it is an embroidery design rather than an unrelated file with the same extension. Record the intended hoop size, design dimensions, thread sequence, and machine model.
2. Open the conversion page on 101convert.com; its online converter can process the file for free without installing software.
3. Choose or upload design.ps, select EXP as the output format, and start the conversion. If the service displays a PS-variant or compatibility option, select the one matching the software that created the file.
4. Download the resulting design.exp file and open it in an embroidery editor that supports EXP. Check the stitch count, finished width and height, rotation, hoop placement, color-change sequence, and jump or trim behavior before transferring it to the machine.
5. If the online converter cannot read the file, open it in the original PS-compatible embroidery program and use File → Export or Save as to create an intermediate format such as DST, then convert that file to EXP. If the original program can export EXP directly, use that route instead.

Quality and compatibility limitations

Converting between stitch formats does not recreate editable embroidery objects. The output can retain the stitch path while losing lettering, fill parameters, underlay settings, pull compensation, appliqué instructions, and the original thread-brand assignments.

EXP files may not carry reliable thread colors. Assign colors manually in the embroidery editor, and confirm every color stop because different programs interpret color-change and stop commands differently. Some Melco workflows also use an accompanying information file for color or design metadata; an EXP file alone may therefore open without the expected palette.

Inspect the design at its actual sewing size. Resizing an already digitized file can cause excessive stitch density, gaps, distorted satin columns, or poor registration. Run a test sew on comparable fabric and stabilizer before production, especially if the conversion changes trims, jumps, or needle stops.
