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.

Initial release: 1994
PDF (Portable Document Format) was developed by Adobe Systems, co-founded by John Warnock and Charles Geschke, with the first version released on June 15, 1993. Built on a simplified PostScript imaging model, PDF encapsulates complete document descriptions — text with fonts, vector graphics, raster images, and interactive elements — in a self-contained file that renders identically across every platform, device, and printer. The format evolved through multiple versions, culminating in its adoption as international standard ISO 32000-1 in 2008 (PDF 1.7) and ISO 32000-2 in 2017 (PDF 2.0), ensuring long-term vendor independence. PDF supports an extraordinary range of capabilities: digital signatures, form fields, annotations, bookmarks, accessibility tags, encryption, JavaScript, multimedia embedding, 3D content, and archival-specific profiles (PDF/A). One advantage is absolute visual fidelity — a PDF document looks exactly the same whether opened on Windows, macOS, Linux, iOS, or Android, printed on any printer, or viewed decades after creation. Universal software support is another core strength: PDF viewers are built into every major operating system and web browser, and the format is read by hundreds of applications worldwide. Specialized ISO profiles like PDF/A (archival), PDF/X (print production), and PDF/UA (accessibility) extend the format's reach into regulated industries. PDF has become the global standard for document exchange in business, government, legal, academic, and publishing contexts.
