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.

VIFF (Visualization Image File Format) is a scientific image format developed by Khoral Research (originally at the University of New Mexico), first appearing around 1990 with the Khoros visual programming environment for image processing and data visualization. VIFF files use a 1024-byte header followed by optional color map data, and the image data itself, with the header containing detailed specifications: data storage type (bit, byte, short, integer, float, double, complex), data encoding (none, CCITT Group 3/4), color space model (none, generic, RGB, HSI, CMYK, and others), and support for multi-band (multi-channel) images with arbitrary numbers of bands. The format accommodates one-dimensional signals, two-dimensional images, three-dimensional volumes, and location data (sparse pixel coordinates), making it versatile beyond simple image storage. VIFF was designed for the Khoros/VisiQuest visual dataflow programming environment, where users constructed image processing pipelines by connecting processing nodes in a graphical canvas — an approach that influenced later systems like AVS, MATLAB Simulink, and LabVIEW. One advantage is scientific data fidelity: VIFF supports the full range of numeric types used in scientific computing (including complex numbers and double-precision floats), stores multi-band datasets natively, and carries calibration metadata — making it suitable for remote sensing, medical imaging, and spectral analysis applications where generic image formats lose information. The format's connection to the Khoros visual programming paradigm provides another notable dimension — VIFF was the standard I/O format for one of the most influential early visual programming environments for scientific image analysis. VIFF files can be read by ImageMagick and legacy Khoros/VisiQuest installations.

Frequently Asked Questions

Why convert PES to VIFF?

VIFF 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 VIFF files?

VIFF 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 VIFF 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.
