About formats

TGA (Truevision Graphics Adapter, also known as TARGA) is a raster image format created by Truevision in 1984 for their line of display adapter cards designed for IBM PC compatibles. The format stores pixel data in a straightforward structure: an 18-byte header specifying dimensions, color depth, and image descriptor flags, optional color map data, and the pixel array in either uncompressed or RLE-compressed form. TGA supports indexed color (8-bit with palette), true color (15-bit, 16-bit, 24-bit), and true color with alpha channel (32-bit), and was one of the first PC image formats to include per-pixel alpha transparency. The format became a staple of the professional graphics industry, widely adopted by video editing suites, 3D rendering software, and game development pipelines throughout the 1990s and 2000s. One advantage is native alpha channel support — TGA was one of the earliest formats offering full 8-bit alpha transparency per pixel, making it the standard output format for 3D renderers and compositing software where layered transparency is essential. The simple, well-documented structure is another strength: TGA files are quick to parse and write, with no complex metadata or container overhead, valued in real-time applications and game engines where loading speed matters. While PNG has largely replaced TGA for general use, the format persists in game development, texture pipelines, and 3D rendering workflows where its simplicity and alpha support remain advantageous.
Developer: Truevision
Initial release: 1984
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 TGA to SIX?

TGA files lack built-in compression — converting to SIX often reduces file size dramatically while preserving quality.

What programs open SIX files?

Terminal emulators with Sixel support (mlterm, xterm, mintty), ImageMagick, and libsixel tools

How fast is TGA to SIX conversion?

Most conversions complete within seconds. Larger or more complex files may take slightly longer, but processing happens on fast cloud servers.

Does TGA to SIX conversion preserve quality?

The converter optimizes for best visual fidelity. SIX may apply compression

Does the conversion preserve transparency?

SIX does not support transparency natively. Alpha channel data from TGA will be flattened against a solid background during conversion.

How many TGA files can I convert at once?

You can upload multiple TGA files in one session. Each converts to SIX separately, and all results are downloadable upon completion.
