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
EPUB (Electronic Publication) is an open ebook standard originally developed by the International Digital Publishing Forum (IDPF) and now maintained by the W3C following the organizations' merger in 2017. The first version carrying the EPUB name was approved in October 2007 as a successor to the Open eBook Publication Structure (OEBPS). An EPUB file is essentially a ZIP archive containing XHTML or HTML5 content documents, CSS stylesheets, images, fonts, and metadata organized according to the Open Packaging Format and Open Container Format specifications. The current major version, EPUB 3, supports reflowable and fixed-layout content, embedded multimedia, JavaScript interactivity, MathML equations, and rich accessibility features including semantic markup and media overlays for synchronized text and audio. A defining advantage is universal device support — unlike proprietary formats, EPUB works natively on virtually every non-Kindle e-reader, tablet, and reading application, from Apple Books and Google Play Books to Kobo and dozens of third-party apps. The reflowable text model is another core strength, automatically adapting pagination, font size, and margins to match any screen dimension and user preference. EPUB's open specification and active W3C stewardship ensure long-term preservation and vendor independence, making it the de facto standard for digital publishing across libraries, academic institutions, and commercial retailers worldwide.
Initial release: October 2007
