About formats

PES is a machine embroidery file format developed by Brother Industries, used primarily with Brother and Babylock home and semi-professional embroidery machines. The format stores complete embroidery designs including stitch coordinates, color sequence information, and design metadata within a structured binary file. Unlike the minimalist DST format, PES files embed thread color data — specifying both the color sequence and palette references — so the machine displays correct thread colors on its LCD panel without manual configuration. PES version numbers have evolved alongside Brother's PE-Design digitizing software, with each release supporting additional machine features like larger hoop sizes, more color stops, and enhanced stitch types. The format handles standard stitch movements, jump stitches, trim commands, and color change markers, with coordinate precision suitable for detailed reproduction. One advantage is embedded color information — when a PES file loads on a compatible machine, it displays the complete color sequence and thread recommendations, streamlining setup. The tight integration with Brother's PE-Design software is another strength, providing a complete workflow from design creation through machine embroidery output with auto-digitizing, lettering tools, and stitch simulation. PES is among the most popular formats in the home embroidery community, supported by major digitizing software and widely available through online design marketplaces.

SIX is a file extension for SIXEL (Six Pixel) graphics data, a bitmap graphics format developed by Digital Equipment Corporation (DEC) in 1983 and introduced with the LA50 dot matrix printer. SIXEL encodes images as a sequence of printable ASCII characters, where each character represents a column of six vertical pixels (a 'sixel') — the character's ASCII value minus 63 provides a 6-bit binary pattern, with each bit controlling one pixel in the vertical column. The encoding is structured as a series of sixel bands (each six pixels tall) across the image width, with control sequences for color selection (up to 256 registers with HLS or RGB specification), repeat counts (run-length encoding for efficiency), carriage return, and newline commands. SIXEL data is transmitted to the output device using DEC's standard escape sequence protocol, embedded within the text stream alongside regular character output. Originally designed for DEC's line of printers and later supported by DEC VT-series terminals (VT240, VT330, VT340), SIXEL has experienced a remarkable revival in modern terminal emulator software. One advantage is terminal-native image display: SIXEL allows images to be rendered directly within a text terminal session without requiring a graphical window system, enabling command-line tools to display graphs, photographs, and previews inline with text output. This capability has driven adoption in modern terminals like mlterm, xterm, WezTerm, and foot. SIX/SIXEL data can be generated by ImageMagick, libsixel, and chafa, and viewed in any SIXEL-capable terminal emulator.

Frequently Asked Questions

Why convert PES to SIX?

SIX is a widely supported format, making it easy to view, share, and use images that originated as embroidery design files in machine embroidery.

What programs open SIX files?

SIX files open in most image viewers and editors — including web browsers, system preview tools, Photoshop, GIMP, and Paint on Windows.

What makes PES files unique?

PES files contain complete stitch-by-stitch instructions for embroidery machines — including thread colors, pattern paths, and design dimensions.

Can I convert multiple PES files at once?

Yes — upload several PES files in a single session and convert them all to SIX simultaneously. Batch processing saves considerable time.

Is my PES data kept private?

Uploaded files are deleted immediately after conversion, and converted files are removed within 24 hours. Your data stays private and secure.
