Does converting an embroidery file change the design?

No. The converter reads the stitches, jumps, trims and colour changes out of your file and writes the same ones back in the new format. The size and the stitch count are unchanged. The only things that can differ are what the target format cannot store — DST and EXP hold no thread colours, and a format with a shorter maximum stitch length will split the few stitches that exceed it.

Is this the same as digitizing?

No, and that distinction matters. Digitizing turns a picture into stitches, and a good one is a design decision. This tool never touches the stitches — it only rewrites the container. If you have an image rather than an embroidery file, use the image converter instead.

Will I lose my thread colours?

Only if you convert to DST or EXP, which have no thread list in the file at all — the colour changes survive, so the machine still stops in the same places, but the operator picks the actual threads. PES, JEF, SEW, VP3 and XXX all store colours, and they are carried across.

Do I need an account to convert an embroidery file?

No. Format conversion is free and needs no account. It costs us almost nothing because there is no digitizing involved, so there is no reason to put it behind a sign-up.

Convert JEF to EXP

Upload a JEF file and download it as EXP for Melco and Bernina. The design is re-encoded, not re-digitized — same stitches, same size, same stitch count.

How to convert JEF to EXP

Choose your .jef file above — it is read in your browser first, so you can check the size and stitch count before anything is sent.
Leave the output set to EXP.
Press Convert file, watch the result stitch out in the preview, then download it.

What changes, and what does not

Nothing about the stitching changes. JEF and EXP are two ways of writing down the same thing — a list of needle positions with commands between them — so the conversion rewrites the list, not the design. Your EXP file will report the same physical size and essentially the same stitch count as the JEF you started with.

The one real loss going from JEF to EXP: EXP files do not store thread colours. JEF carries a thread list; EXP carries only stitches and colour-change commands. Your machine will stop in exactly the same places, but it will not know which colour to ask for — you set the threads at the machine. Note the colour order from the preview above before you download.

Which machines read EXP?

EXP is the native format for Melco and Bernina. If you are not sure what your machine takes, its manual lists the formats it will load from a USB stick — and the PES vs DST vs JEF comparison covers what each one stores.

Formats you can convert between

Format	Machines	Stores thread colours?
PES	Brother, Baby Lock	Yes
DST	Tajima and most industrial multi-needle machines	No — colour changes only
JEF	Janome, Elna	Yes
SEW	Older Janome — Memory Craft 5700, 8000, 9000	Yes
EXP	Melco, Bernina	No — colour changes only
VP3	Husqvarna Viking, Pfaff	Yes
XXX	Singer, Compucon	Yes

Files can also be read from a wider set — HUS, SHV, PHB, PHC, JPX, EMD, PCS, U01, TAP and several older industrial formats — even though those are not offered as outputs.

Frequently asked questions

No. The stitches, jumps, trims and colour changes are read out of your file and written back in the new format, so the size and stitch count are unchanged. The only differences come from what the target format cannot store: DST and EXP hold no thread colours, and a format with a shorter maximum stitch length splits the few stitches that exceed it.

No, and the distinction matters. Digitizing turns a picture into stitches. This only rewrites the container around stitches that already exist. If you are starting from an image, use the image to embroidery converter.

No. Format conversion is free and account-free. There is no digitizing behind it, so it costs almost nothing to run and there is no reason to put it behind a sign-up.

Yes — that is what the preview under the result is for. It plays the converted file in the order the machine will sew it, so you can confirm the colour blocks and stop points before committing. The stitch simulator does the same for any file you already have.
