PES to DST: what actually changes
An embroidery file is a list of stitches with machine commands: move, jump, trim, change colour. Converting PES to DST means reading that list and rewriting it in the other machine's grammar. The stitches don't move; what changes is what each format can say around them. PES keeps thread colours (the 64-colour Brother palette) and a preview thumbnail. DST carries no thread colours: the colour order is on the printable run sheet.
- Drop the PES file above (with its .rgb colour file if it has one). The studio opens it and shows the stitched design in relief with stitch count, colours and size.
- Check: stitches outside the hoop, untrimmed jumps and very short stitches are flagged and can be cleaned in one click. You can also resize; beyond 15 % the studio re-digitizes the shapes and recalculates every stitch instead of stretching them.
- Export as DST. Colour changes, trims and stops are re-encoded following DST conventions.
The usual conversion traps
- Colours. PES carries colours; they are kept and matched to the DST palette when it has one.
- Trims. In DST a trim is three consecutive jumps; in PES, EXP and VP3 it is explicit; in JEF three zero jumps. The studio translates these conventions, which naive converters forget (result: untrimmed threads to cut by hand).
- Size. Conversion never changes size. To enlarge by more than 15 %, use “Re-digitize”, which recalculates density.
Is it free?
Opening, converting, previewing the stitches in 3D and running the quality check are free and need no account. Without an account, the simple converter (automatic settings) sends the machine file to your e-mail address. Downloading the machine file directly needs a free account (Discovery plan: 3 files a month, designs up to 30,000 stitches); the Loisir plan, at €9.99 a month, gives 10, designs up to 50,000 stitches; shops that produce every day take the Atelier plan at €19.99 a month or €199.99 a year. Atelier can be tried free for 14 days.
Frequently asked questions
Does PES → DST lose quality?
No: stitch coordinates are copied as they are, to a tenth of a millimetre. What may change are the displayed colours and the trim encoding, which the studio translates.
Can I convert several files at once?
Yes: the file viewer (Import ▸ Viewer) opens a whole folder, shows thumbnails and converts each design to the chosen format.
