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.

SNB is a proprietary ebook format developed by Shanghai Nutshell Electronics, a subsidiary of Shanda Interactive Entertainment, for the Bambook e-reader launched in August 2010. The format is structurally based on EPUB principles, packaging HTML content, CSS styling, images, and metadata within a compressed archive, but uses a proprietary container that restricts native playback to Bambook devices and associated software. Shanda designed the Bambook and its SNB ecosystem as an integrated reading platform tied to the Cloudary literature portal (later rebranded as China Literature), one of China's largest online publishing networks hosting millions of web novels and serialized fiction. The format supported reflowable text, chapter navigation, bookmarks, and basic typographic controls suited to Chinese-language content display. One advantage was tight integration with Shanda's massive content catalog, providing readers instant access to an enormous library of Chinese-language literature directly through the device. The Bambook was initially offered at a heavily subsidized price point, using the content ecosystem to drive revenue — a model that preceded similar strategies by other e-reader manufacturers. While the Bambook hardware line was eventually discontinued as the Chinese market shifted toward tablet-based reading apps, SNB files from that era can be converted to standard formats using tools like Calibre with appropriate plugins. The format represents an interesting case study in platform-specific ebook ecosystems within the Chinese digital publishing landscape.

Frequently Asked Questions

Why convert PES to SNB?

Placing PES images into SNB format lets recipients view them in standard document readers — far more accessible than raw PES files.

What programs open SNB files?

Standard document viewers handle SNB files — Microsoft Office, LibreOffice, Adobe Reader, or Calibre for e-book formats.

Why is PES not widely supported?

PES is a specialized machine embroidery format made for Brother equipment. Standard image viewers lack the ability to interpret stitch pattern data.

How is image quality handled during conversion?

The converter extracts full image data from PES and encodes it into SNB at the highest quality the target format allows. No unnecessary loss.

Do I need to install anything?

No installation needed — the conversion happens entirely online. Open the converter in any modern web browser and your device handles the rest.
