EXP to DST Converter
Convert Melco EXP embroidery files to Tajima DST — stitch-for-stitch, free, in your browser.
Quick answer: To convert EXP to DST for free, you need a stitch-level converter, not an image converter — embroidery files store needle movements, not pictures. This tool decodes the Melco EXP stitch commands in your browser and re-encodes them as Tajima DST 1:1, preserving every stitch, jump and color change at the original size.
This converter decodes the actual stitch commands in your Melco EXP file and re-encodes them as a Tajima DST file — every stitch, jump and color change preserved exactly, at the original size. It is not an image trace, and the file never leaves your browser.
Melco/Bernina designs need DST for Tajima-compatible commercial machines.
Beware of generic "file converter" websites offering this conversion: most treat embroidery files like images and produce output no machine can sew. A stitch file must be converted at the stitch level — that's what this does.
How it works
- Drop a Melco EXP (.exp) file — it is decoded locally in your browser.
- Check the detected stitch count, size and color changes.
- Download the Tajima DST (.dst) file, converted stitch-for-stitch.
Good to know
- Conversion preserves the design 1:1 — it cannot resize it or adjust stitch densities for different fabric. If the size or fabric changes, the design should be re-digitized from the original artwork.
- DST physically cannot store thread colors — the machine operator assigns threads at sew-out. Keep your color sequence notes.
- Always run a test sew-out before production, as with any converted file.
Frequently asked questions
Does converting EXP to DST lose quality?
No — the stitch data is copied 1:1 (we validated the conversion against the industry reference library on real production files). What conversion can never do is adapt the design to a new size or fabric; that's re-digitizing, not converting.
Is my design file uploaded to your server?
No. The whole conversion runs inside your browser — for commercial designs that matters.
Why does my converted DST file sew wrong colors?
Machine formats like DST don't store thread colors at all — the operator sets the thread sequence at the machine. The stitches themselves are unchanged.
Can you convert a JPG or PNG logo this way?
No — an image has no stitches to convert. Turning artwork into an embroidery file is digitizing, a manual craft. DigitEMB does exactly that from $10 with free edits.
