About formats

NRW is a variant of Nikon's RAW image format used specifically by their COOLPIX advanced compact cameras, introduced in 2008 with models like the COOLPIX P6000. While functionally similar to NEF (Nikon Electronic Format) in preserving unprocessed sensor data, NRW uses a simplified container structure tailored to the compact camera platform's processing constraints and smaller sensor sizes. NRW files store 12-bit raw Bayer-pattern data from the camera's smaller-format CMOS or CCD sensor, along with embedded JPEG thumbnails, basic EXIF metadata, and a subset of Nikon's MakerNote information. The format was designed for the COOLPIX cameras that bridged the gap between consumer point-and-shoots and interchangeable-lens systems — cameras like the P7000/P7100/P7700/P7800 series and the P330/P340 that attracted enthusiasts wanting RAW flexibility in a pocketable body. Unlike the full NEF format, NRW files typically use a fixed compression scheme and omit some of the more extensive metadata found in NEF files from Nikon's SLR and mirrorless bodies. One advantage is that NRW provides genuine RAW capture flexibility in compact camera form factors where most competitors offered only JPEG — photographers can apply custom white balance, adjust exposure, and control noise reduction during post-processing rather than relying on the camera's built-in processing. Software compatibility is another strength: NRW files are supported by Adobe Lightroom, Adobe Camera Raw, Nikon's ViewNX/NX Studio, dcraw, and other major RAW processors.
Developer: Nikon
Initial release: 2008
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 NRW to SIX?

NRW files capture more data than JPEG from your Coolpix but need conversion to SIX for sharing on social media or via email.

What opens SIX files?

SIX files can be opened with DEC terminal emulators, xterm, mlterm, and Sixel-capable terminal applications.

Will the SIX output retain my photo quality?

The converter processes raw image data from NRW and produces a high-quality SIX — results look great for viewing and sharing.

Can I convert multiple NRW files to SIX at once?

Yes — upload several NRW files simultaneously and each converts to SIX independently for individual download.

Are my NRW files safe during conversion?

Uploaded NRW files are deleted immediately after conversion. SIX outputs are automatically removed within 24 hours.
