About formats

SFW is a proprietary image format created by Seattle FilmWorks (later PhotoWorks) for their Pictures on Disk mail-order photo service, active primarily from 1994 through the early 2000s. Customers who sent film to Seattle FilmWorks for developing could opt to receive their photos back on 3.5-inch floppy disks in addition to (or instead of) traditional prints. SFW files contained the scanned photographs in a JPEG-based encoding wrapped in a custom header, designed to be viewed through Seattle FilmWorks' proprietary desktop software. The service was notably popular in the mid-1990s, offering one of the most accessible ways for ordinary consumers to obtain digital versions of their film photographs before consumer scanners and digital cameras became affordable. SFW files typically contained modest-resolution scans appropriate for screen viewing and small prints — sufficient quality for the 640x480 and 800x600 monitor resolutions common at the time. One advantage of SFW files is their role as historical artifacts: for many families, SFW disks represent the only digital copies of film-era photographs from the 1990s, preserved on media that predates widespread home scanning and digital photography. The underlying JPEG data ensures reasonable image quality despite the proprietary wrapper. Extracting images from SFW files is straightforward: tools like XnView, ImageMagick, and specialized SFW-to-JPEG converters can strip the proprietary header and save the standard JPEG data, making these nostalgic files accessible on any modern device.
Developer: Seattle FilmWorks
Initial release: 1994
RGB is a raw (headerless) image format that stores pixel data as a flat sequence of red, green, and blue sample values with no container structure, compression, or metadata. Each pixel is represented by three consecutive bytes (in 8-bit mode) — one for red intensity, one for green, and one for blue — written in scanline order from the top-left corner of the image to the bottom-right. Because there is no header, the image dimensions and bit depth must be specified externally when reading the file. The format supports multiple bit depths: 8-bit (0-255 per channel), 16-bit (0-65535 per channel), and floating-point variants, with 8-bit being the most common. The RGB color model itself reflects how display hardware produces color — by mixing red, green, and blue light at varying intensities — and raw RGB files represent this model in its most direct digital form. With 8-bit channels, three bytes per pixel yield a 24-bit color palette capable of representing 16,777,216 distinct colors. One advantage is zero-overhead processing: without headers or compression to parse, raw RGB data can be memory-mapped, fed directly into GPU textures, or piped between processing stages with minimal latency — valuable in real-time imaging, scientific instrumentation, and computer vision pipelines where every millisecond matters. The format's universal simplicity provides another practical strength — any programming language can read or write raw pixel data with just basic file I/O, making it a reliable interchange format between custom software that may not share support for structured image containers. Raw RGB files are handled by ImageMagick, FFmpeg, and various scientific and graphics tools.

Frequently Asked Questions

Why convert SFW to RGB?

SFW is a defunct proprietary format — the company no longer exists. Converting to RGB rescues your irreplaceable 1990s photos permanently.

What programs can open RGB?

GIMP, Photoshop, Blender, and IrfanView open SGI RGB images. This format was standard on Silicon Graphics workstations.

How accurate is SFW to RGB conversion?

The conversion keeps your image data intact — RGB does not introduce compression artifacts, ensuring the output matches the original closely.

How long does SFW to RGB conversion take?

The process is fast — cloud-based processing handles SFW to RGB conversion in seconds for standard-sized images, even on slower connections.

Can I convert multiple SFW images at once?

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