Convert EPDF to SFW

Understanding EPDF and SFW file formats

EPDF typically refers to an Encapsulated Portable Document Format, a variant of the standard PDF file used for sharing documents with embedded fonts, images, and layouts. SFW stands for Seattle FilmWorks Image, a raster image format once used by the Seattle FilmWorks photo processing service. SFW files are uncommon today and are primarily used for archiving old photographs.

Why convert EPDF to SFW?

Converting an EPDF to SFW is rare, but may be necessary if you need to extract images from a PDF and save them in the SFW format for compatibility with legacy software or archival purposes.

How to convert EPDF to SFW

There is no direct converter from EPDF to SFW, as these formats serve different purposes. The process involves two main steps:

1. Extract images from the EPDF: Use a PDF reader or editor to export images from the EPDF file.
2. Convert extracted images to SFW: Use an image converter that supports SFW output.

Recommended software for conversion

• Adobe Acrobat Reader: Open your EPDF and use File → Export To → Image to extract images in a common format (e.g., JPEG, PNG).
• XnView: A powerful image viewer and converter that supports SFW. Open the extracted image and use File → Save As to select SFW as the output format.

Step-by-step conversion process

1. Open the EPDF in Adobe Acrobat Reader.
2. Export images using File → Export To → Image.
3. Install and open XnView.
4. Open the exported image in XnView.
5. Go to File → Save As and choose SFW as the format.
6. Save the file to complete the conversion.

Tips and considerations

• SFW is an outdated format; consider using more modern formats unless SFW is specifically required.
• Not all image converters support SFW. XnView is one of the few that does.
• Quality may be lost during conversion, especially if the original images are compressed.
