About formats

SIXEL (Six Pixel) is a bitmap graphics encoding format created by Digital Equipment Corporation (DEC) in 1983 for rendering images on character-cell printers and video terminals. The name derives from the encoding's fundamental unit: a column of six pixels represented by a single ASCII character. Each printable character in the sixel data stream (ASCII 63-126) encodes a 6-pixel vertical column, with the character's binary value determining which pixels are on or off. Color is specified through register-based palette control: a Select Color Sequence assigns an HLS or RGB color value to a numbered register, and subsequent sixel characters use that color until another register is selected. The encoding supports raster attributes for specifying pixel aspect ratio and image dimensions, repeat sequences (! followed by a count and character) for run-length compression of identical columns, and $ (carriage return) and - (new line) for navigating the sixel grid. DEC implemented SIXEL support in their VT240, VT241, VT330, and VT340 terminals, as well as multiple printer models. One advantage of the SIXEL encoding is its ASCII-clean nature: the data stream consists entirely of printable characters and standard control sequences, meaning SIXEL graphics can be transmitted through any text-based communication channel — serial terminals, SSH sessions, telnet connections — without requiring binary-safe transport or protocol modifications. The format's modern renaissance provides another remarkable dimension: after decades of obscurity, SIXEL support has been implemented in numerous contemporary terminal emulators, enabling inline image display in command-line workflows. SIXEL output can be generated by ImageMagick, libsixel, chafa, and various plotting libraries.

JPE is an alternate file extension for JPEG (Joint Photographic Experts Group) compressed images, functionally identical to .jpg and .jpeg files. The .jpe extension originated in early computing environments where three-character file extensions were the norm (as on MS-DOS and Windows 3.x), and some applications registered .jpe as an additional JPEG-associated extension alongside .jpg. JPE files contain standard JPEG-compressed data: the same DCT-based lossy compression that transforms 8x8 pixel blocks into frequency coefficients, quantizes them according to quality settings, and encodes the result using Huffman entropy coding. The file structure follows the JFIF or Exif specification, beginning with an SOI marker (0xFFD8), followed by application-specific markers (APP0 for JFIF, APP1 for Exif), quantization and Huffman table definitions, and the entropy-coded image data. JPE files support 8-bit grayscale and 24-bit color images at any resolution, and may contain embedded ICC color profiles, Exif metadata from digital cameras (exposure, GPS, lens data), IPTC captions, and XMP metadata. The JPEG compression algorithm achieves its remarkable efficiency by exploiting the human visual system's reduced sensitivity to high-frequency spatial detail and color differences — discarding information the eye cannot readily perceive. One advantage is the extension's broad registration in MIME type databases and file association tables, ensuring that email clients, web servers, and operating systems recognize .jpe files as JPEG images and handle them correctly. The format's universal reach is another definitive strength — JPE/JPEG is supported by literally every image-capable software and hardware device manufactured in the last three decades. Files are processable by any tool that handles JPEG, including all browsers, editors, and programming libraries.
Initial release: 1992

Frequently Asked Questions

Why convert SIXEL to JPE?

SIXEL images only appear inside terminal emulators. Exporting to JPE lets you use that artwork in any image viewer or editor.

What programs can open JPE?

All web browsers, Photoshop, GIMP, IrfanView, and every standard photo viewer open JPE files — it is simply an alternate JPEG extension.

Is the conversion from SIXEL to JPE lossless?

A small amount of data is discarded during lossy JPE encoding. For everyday viewing and sharing, the quality difference is imperceptible.

How long does SIXEL to JPE conversion take?

Conversion is handled on cloud servers and usually completes in a few seconds. Larger or higher-resolution SIXEL images may take slightly longer.

Can I convert multiple SIXEL images at once?

Absolutely. Add several SIXEL images at once, set JPE as the output, and the converter processes them all in parallel for maximum efficiency.
