Why PNG is a good starting point
PNGs keep hard edges without JPG compression noise, and transparency tells the digitizer exactly what to stitch. If your PNG has a white box behind the logo, remove it first.
Size the design for your hoop
Brother home machines commonly use 4×4 in (100×100 mm) or 5×7 in (130×180 mm) hoops. Convert at a size that fits your hoop with a little margin — resizing a PES file afterwards changes stitch density.
Keep colours machine-friendly
Every colour is a thread change. Merge near-identical shades, and remember small text under about 5 mm tall becomes hard to read in thread.
Convert and transfer
Upload the PNG to StitchAI Pro, set the size in mm or inches, preview the stitches and download the PES. Copy it to a USB stick (or send it via your machine's app) and load it on the machine. New accounts get 15 free credits — enough for one embroidery conversion.
Test-sew before the real garment
Use stabilizer that matches your fabric and sew a sample first. If you see gaps between colours or puckering, re-run with adjusted settings.
