How to convert PNG to EXP
- 1Drop your PNG into the tool above. Transparent areas are left unstitched.
- 2Set the stitched width in millimetres or inches for your hoop, then check the stitch preview, stitch count and sewing time.
- 3Note the colour order: EXP has no thread colours, so the machine shows defaults. Follow the production sheet in the ZIP.
- 4Download the ZIP (PES, DST, JEF and EXP), unzip it and copy the EXP file to your machine.
Preparing your PNG for embroidery
PNG is the best everyday starting point for embroidery. It's lossless, so edges stay crisp and flat colours stay flat, and it can carry a transparent background. StitchMyPic leaves transparent areas unstitched: the fabric shows through instead of becoming a large fill with thousands of extra stitches.
- Export about 10 pixels per millimetre of finished embroidery: 1000 px wide for a 100 mm design.
- Keep the background transparent, or one flat colour that you leave out.
- Remove glows, drop shadows and soft edges. Three to six flat colours stitch best.
What you get in the EXP file
EXP is the Melco "expanded" format, read natively by Melco commercial machines and by Bernina home machines. It's about as simple as a stitch file gets: no header, just a pair of signed bytes for each move (up to 12.7 mm), with escape codes for jumps and colour changes. Like DST it carries no thread colours. Bernina's software saves companion files with colours and a preview image next to the EXP, but the machine sews from the EXP alone.

PNG to EXP: common questions
Is the PNG to EXP converter free?
The preview is free and needs no account: drop your PNG above and you see the stitches, stitch count and sewing time. Downloading uses one credit, from $2.58 per design, and new accounts get one free credit. The ZIP contains EXP plus the other three formats.
Is the transparent background of my PNG stitched?
No. Transparent pixels are left out, so the garment colour shows through, which is usually what you want for logos on shirts, bags and caps. If you'd like a filled background, give the PNG a solid background colour before you upload it.
Do I need the .INF and .BMP files that Bernina uses?
No. Bernina's software saves them next to the EXP to carry thread colours and a preview picture, but the machine sews from the EXP alone. Without them the design sews exactly the same; the screen just shows default colours instead of your threads.
Is EXP the same file for Bernina and Melco?
Yes, both read the same Melco expanded stitch data. Bernina home machines load it from a USB stick and Melco commercial machines read it natively. On either one, set the colours from the production sheet, because EXP doesn't store them.
How big should I stitch my design?
Most logos and badges look best 70–120 mm wide. Keep capital letters at least 6 mm tall and lines at least 1 mm wide at the final size, and leave 5–10 mm between the design and the edge of your hoop's sewing field. The editor warns you if the design doesn't fit.
