About BMP files
BMP is the uncompressed Windows bitmap format. BMP files are completely uncompressed, so there are zero compression artifacts — every pixel is exactly as authored. BMP has no transparency, so the automatic background removal detects and strips solid backgrounds instead.
Tip: Keep the background a single flat colour so the automatic background removal can strip it cleanly.
About the DST format
DST (Tajima stitch format) is read by Tajima commercial machines and nearly every multi-needle or commercial embroidery machine — DST is the industry's most widely supported format. The format stores no thread colours at all — only stitches, jumps, and colour-stop commands. Transfer by USB or network. Because DST carries only colour stops, you assign the actual thread colours at the machine.
