What is SFW (Seattle FilmWorks)?
SFW is a proprietary image format developed by Seattle FilmWorks, a photo finishing company that operated from the 1970s to the late 2000s. It's similar to PWP format from the same company.
This format was used by Seattle FilmWorks as part of their photofinishing service, where customers could receive digital versions of their film photos on floppy disks or other media.
SFW files typically contain compressed image data along with various metadata about the image, such as date, time, and basic camera information if available from the film processing.
How to open SFW?
Since Seattle FilmWorks is no longer in business, opening SFW files has become challenging. Some versions of IrfanView with plugins may support the format.
Specialized conversion utilities like GraphicConverter (for Mac) and XnView (cross-platform) might be able to open and convert SFW files to more common formats.
For bulk conversion of legacy SFW archives, batch processing utilities with SFW support can be helpful, though finding current software with good SFW compatibility may require some research.
SFW is Developed by: Seattle FilmWorks (later PhotoWorks)
SFW was Released on: 1990s

Preserving SFW Images
If you have SFW files in your archives, it's highly recommended to convert them to standard, widely supported formats like JPEG or TIFF for long-term preservation.
The proprietary nature of the format and the fact that the company no longer exists means that support for SFW may continue to decline over time, potentially leading to inaccessibility.
When converting SFW files, be sure to preserve as much of the original image quality as possible by using lossless formats or high-quality settings for lossy formats.
