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.

CUR is the cursor image format for Microsoft Windows, structurally nearly identical to the ICO (icon) format but with the addition of a hotspot coordinate that identifies the precise pixel position where mouse clicks register. Introduced with early Windows versions, CUR files use the same container structure as ICO: a directory header listing one or more image entries, each specifying dimensions and color depth, followed by the pixel data for each variant. Like ICO, a single CUR file can contain multiple images at different sizes and color depths, allowing Windows to select the most appropriate cursor image for the current display resolution and color settings. Image data within CUR files can be stored as BMP pixel arrays (for legacy compatibility) or as embedded PNG images (supported since Windows Vista) for alpha-blended cursors with smooth edges. The hotspot coordinate — the distinguishing feature separating CUR from ICO — is stored as an X,Y pair in the directory entry header, typically pointing to the tip of an arrow or the center of a crosshair. One advantage is multi-resolution packaging: a single CUR file provides appropriate cursor imagery across display densities from standard DPI to high-DPI screens. Native Windows integration is another strength — CUR files are loaded directly by the operating system for mouse cursor display without any third-party software. CUR files are used by application developers and theme creators to customize the pointing experience across Windows environments.

Frequently Asked Questions

Why convert SFW to CUR?

Seattle FilmWorks locked photos in a proprietary format. Converting SFW to CUR frees your personal photographs for modern use.

What programs can open CUR?

Windows uses CUR files natively as mouse cursors. IrfanView, GIMP, and dedicated cursor editors open CUR for viewing and editing.

How accurate is SFW to CUR conversion?

CUR preserves image data without lossy compression, so the visual content from your SFW is retained faithfully during conversion.

Is SFW to CUR conversion fast?

Most SFW images convert to CUR within seconds. The exact time depends on the resolution and complexity of the source, but it is typically quick.

Does Convertio support batch SFW to CUR conversion?

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

Can I recover photos from old floppy disks?

If you can read the SFW files from the disk onto your computer, Convertio will convert them to CUR — rescuing those memories.
