About formats

SRF (Sony RAW Format) is the earliest proprietary RAW image format used by Sony digital cameras, introduced in 2003 with the Cyber-shot DSC-F828 and also used by the DSC-V3 compact camera. SRF files capture the unprocessed sensor readout at 12 bits per channel, preserving the raw Bayer-pattern data from the camera's CCD sensor before any demosaicing, white balance, or compression processing. The DSC-F828 was notable for its unique 4-color RGBE (Red, Green, Blue, Emerald) CCD sensor design — an attempt to capture a wider color gamut by adding a cyan-shifted fourth color filter element — and SRF files from this camera store the raw 4-color mosaic data needed to take advantage of this unconventional sensor layout. The format uses a proprietary container structure with Sony-specific metadata tags recording exposure parameters, lens position, and camera settings. SRF was succeeded by SR2 and then ARW as Sony expanded into interchangeable-lens cameras with the Alpha DSLR system from 2006 onward. One advantage is the capture of data from genuinely innovative sensor technology — the DSC-F828's 4-color filter array was a unique experiment in consumer camera design, and SRF files preserve the raw 4-channel data that enables exploration of the extended color gamut this sensor design was intended to provide, particularly in the cyan-green portion of the spectrum where standard Bayer sensors have gaps. Despite the format's obscurity, SRF files remain processable: Adobe Camera Raw, dcraw, LibRaw, and RawTherapee all support SRF, ensuring these early Sony RAW files remain accessible for modern processing.

WMF (Windows Metafile) is a vector graphics format created by Microsoft, introduced with Windows 3.0 in May 1990 as the platform's native format for recording and replaying graphical operations. A WMF file captures a sequence of GDI (Graphics Device Interface) drawing commands — lines, rectangles, ellipses, polygons, text, and bitmap blits — in the order they were issued, serializing screen or printer output into a replayable file. The format uses a 16-bit coordinate space and organizes records as a linear stream of function calls with their parameters, preceded by a header specifying the bounding rectangle and resolution. WMF became deeply integrated into the Windows ecosystem as the default format for clip art collections, Office document graphics, and clipboard vector interchange during the 1990s — Microsoft Office shipped with thousands of WMF clip art images that defined a visual era of desktop publishing. One advantage is pervasive compatibility: virtually every Windows application from the past three decades can render WMF content, making it one of the most widely supported vector formats in existence. The lightweight recording model is another strength — WMF files are compact and render quickly because they replay native system drawing calls rather than interpreting a complex graphics language. While 16-bit limitations and lack of transparency and Bezier curves led Microsoft to develop EMF as a 32-bit replacement, WMF files remain ubiquitous in legacy documents and across current Windows software.

Frequently Asked Questions

Why convert SRF to WMF?

First-generation Sony Alpha cameras produced SRF files that are now nearly impossible to open — converting to WMF brings them back to life.

What opens WMF files?

WMF files can be opened with Microsoft Office, Windows applications, LibreOffice, and Inkscape.

Does converting SRF to WMF lose quality?

Convertio extracts full sensor data from your SRF file. The WMF output retains excellent quality within the target format capabilities.

How long does SRF to WMF conversion take?

Most conversions finish in just a few seconds — server-side processing handles the heavy lifting, not your device.

Can I convert multiple SRF files to WMF at once?

Yes — upload several SRF files simultaneously and each converts to WMF independently for individual download.

Is there a cost for converting SRF to WMF?

Convertio offers free conversions for standard use. Premium plans are available for users who need higher volume.
