About formats

VIPS is the native file format of the libvips image processing library, originally developed by John Cupitt and Kirk Martinez at the National Gallery in London during the VASARI project (1989-1993) for high-resolution digitization and analysis of paintings. The VIPS format stores large images in a simple, memory-mappable layout: a header containing image dimensions, number of bands (channels), data type (8/16/32-bit integer, float, double, complex), color interpretation, resolution, and offset metadata, followed by the raw pixel data in band-interleaved format. This straightforward layout allows the operating system's virtual memory manager to map the file directly into address space, enabling libvips to process images much larger than available RAM by paging portions in and out as needed — a technique called demand-driven evaluation. VIPS files support images with any number of bands at any of the supported numeric types, accommodating everything from standard RGB photographs to hyperspectral datasets with hundreds of bands. One advantage is large-image performance: libvips's architecture processes images in small tiles evaluated on demand, meaning a 100,000 x 100,000 pixel image can be cropped, resized, sharpened, and saved without loading the entire image into memory — a capability that makes VIPS the engine behind image processing services handling millions of web images. The format's scientific heritage is another strength — the VASARI project required analyzing paintings at ultra-high resolution with multispectral imaging, and the VIPS format's support for arbitrary band counts and floating-point precision reflects these computational imaging origins. VIPS files are primarily used with the libvips library (available for C, Python, Ruby, and other languages) and can be converted to other formats via vips command-line tools or ImageMagick.
Initial release: 1993
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.

How do I open SIX files?

You can open SIX with Sixel-capable terminals like xterm, mlterm. No specialized software is needed on most modern systems.

Can I convert multiple VIPS files at once?

Batch conversion is supported — upload several VIPS files and each will be independently converted to SIX format.

Is VIPS to SIX conversion accurate?

Yes — the conversion engine renders VIPS content precisely into SIX format, retaining visual accuracy throughout.

Is the VIPS to SIX conversion free?

You can convert VIPS to SIX for free on convertio.tools. Larger or more frequent conversions are available with a subscription plan.

Does the conversion happen on my device?

Convertio handles all processing on its servers — your device just uploads the VIPS and downloads the SIX result.
