PES vs DST: Which Embroidery File Format Do You Need?

PES and DST are the two formats you'll run into most. They're not interchangeable, but they're closely related — both ultimately describe the same thing: where the needle goes and when to change thread. Here's how to choose.

DST: the universal standard

DST is a Tajima commercial format that every machine reads. It stores stitches, jumps, trims, and color-change stops — nothing else. No thread colors, no hoop data, no preview image. It's the lowest common denominator, which is exactly why it's so reliable: there's almost nothing in it that can go wrong.

PES: Brother's native format

PES is the native format for Brother and Babylock home machines. It contains everything DST has plus actual thread color data, design thumbnails, and hoop information. When you load a PES on a Brother machine, you see the design rendered in its real colors on the screen — with a DST you see a generic color sequence and assign threads yourself.

Which one should you use?

• Brother/Babylock machine: PES if available, DST works fine
• Janome: JEF preferred, DST works
• Commercial machines (Tajima, Barudan, SWF): DST is the native choice
• Sharing designs with others: DST — everyone can read it
• You only have a DST and a Brother machine: just use it and set colors manually

Converting between formats

Any embroidery software converts between formats losslessly at the stitch level — a stitch is a stitch. Free tools like Ink/Stitch, or online converters, handle DST↔PES conversion in seconds. What you lose converting to DST is only the metadata (colors), never the sewing data.

embroider.app currently exports DST for exactly this reason: it's the one format guaranteed to work in every machine, and the stitch-accurate preview shows you the real color sequence to match at the machine.
