How to Convert PNG to PES for Embroidery: Step-by-Step Guide

An embroidery machine cannot stitch a PNG. It needs a PES file, which tells the machine where to place every stitch and which thread color to use. Turning a flat picture into stitch instructions is called digitizing.

PNG vs PES

A PNG is a grid of colored pixels. A PES is a list of machine commands: stitch types, direction, color changes and trims. PES works on Brother, Babylock and many Bernina machines. You cannot just rename the file or use "Save as", because the stitch type and order must be decided first.

Three ways to convert

• Auto-convert tools: fast, but only good for simple flat-color logos. Small text and fine detail come out rough.
• Manual digitizing: trace the shapes in software like Wilcom, Hatch or Brother PE-Design and choose each stitch type. You get full control, but there is a learning curve.
• Professional service: the safest choice for business orders and complex designs. Our PNG to PES digitizing service delivers stitch-ready files.

Step by step

1. Prepare a high-resolution PNG (1000+ pixels) with a clean background and 4 to 8 flat colors.
2. Import it into your embroidery software and set the real stitch size, for example 3 inches for a left-chest logo.
3. Digitize: fill stitch for large areas, satin stitch for borders and narrow columns under about 8 mm, run stitch for fine lines.
4. Set density and underlay so the stitches sit stable on the fabric.
5. Order the objects so background elements stitch first and details last, then match your thread colors.
6. Preview in the stitch simulator and check for gaps and long jumps.
7. Export as PES and copy it to your machine by USB.
8. Test stitch on scrap fabric before sewing the final garment.

Tips for cleaner results

• Keep lettering taller than about 5 mm, or it will fill in.
• Remove gradients. Thread is a solid color, so use separate color blocks.
• Stabilize the fabric: cut-away for knits, tear-away for woven fabric.
• Save the original design file, since PES is hard to edit later.

Common mistakes

• Renaming a PNG to .pes. The machine cannot read it.
• Using a blurry, low-resolution image.
• Skipping the test stitch.
• Enlarging a finished PES by a lot without re-digitizing.

Conclusion

Converting PNG to PES is really digitizing. Use auto-convert for simple logos, manual digitizing when you want control, and a professional service when the result must be right the first time. Start with a clean image and always run a test stitch.
