About formats

ARW (Alpha RAW) is Sony's proprietary RAW image format used across the Alpha mirrorless and DSLR camera lineup, introduced in 2006 with the Alpha DSLR-A100. Built on a TIFF-like container structure, ARW stores the unprocessed readout from Sony's Exmor and Exmor R/RS CMOS sensors at 12 or 14 bits per pixel, retaining the complete dynamic range and color information before any in-camera processing is applied. The format includes detailed metadata — AF point data, lens distortion profiles, face detection results, and real-time tracking information from newer bodies — enabling RAW processors to replicate or refine the camera's processing decisions after the fact. ARW has evolved through several revisions: ARW 1.0 used simple per-row compression, ARW 2.0 introduced a more efficient delta encoding scheme, and ARW 4.0 added lossless compression support. One advantage is the exceptional latitude for exposure correction: Sony's sensor technology captures 14+ stops of dynamic range in many bodies, and the uncompressed ARW data preserves this range fully, allowing photographers to recover shadow detail or pull back highlights well beyond what JPEG permits. The format's integration with Sony's ecosystem is another practical strength — Creative Styles, Picture Profiles, and in-camera lens corrections are stored as metadata tags rather than baked into the data, giving photographers complete flexibility during post-processing. ARW files are supported by Adobe Lightroom, Capture One, DxO PhotoLab, and Sony's own Imaging Edge software suite.

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 ARW to WMF?

Converting ARW raster data to a vector-based format makes the image resolution-independent — useful for certain design, illustration, and print workflows.

What programs open WMF?

You can open WMF in Microsoft Office, Windows apps, LibreOffice, and Inkscape.

Can I convert ARW from Google Drive?

Yes — import Sony ARW photos directly from Google Drive or Dropbox without downloading them to your device first. Cloud-to-cloud workflow.

What resolution can I convert?

The converter handles ARW images at their original resolution — from compact camera shots to high-megapixel Sony sensor outputs.

Does the conversion preserve image quality?

The converter processes your Sony ARW sensor data carefully to produce the best possible WMF output. Quality depends on the target format's capabilities.
