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.

Initial release: 2006
SK is the native file format of Skencil (originally named Sketch), a free vector graphics editor for Linux created by Bernhard Herzog, with the first public release on October 31, 1998. Skencil holds historical significance as one of the earliest full-featured vector drawing applications written almost entirely in Python, with only performance-critical rendering components implemented in C. The SK file format uses a text-based, Python-like syntax to describe document structure — pages, layers, groups, and individual graphic objects are represented as nested statements with parameters specifying coordinates, colors, line styles, and transformations. The format supports Bezier curves, rectangles, ellipses, text objects with font specifications, imported raster images, gradient and pattern fills, and hierarchical grouping with affine transforms. One advantage is human readability — SK files can be opened in any text editor, making it possible to inspect, modify, or generate artwork programmatically using simple scripts. The Python-native structure also provides a benefit for automation: since Skencil itself is a Python application, the file format integrates naturally with scripting workflows for batch processing and procedural graphic generation. While Skencil's development slowed after the mid-2000s, its SK format became the foundation for the sK1 project, which extended the format and continued active open-source vector graphics development. SK files remain convertible through sK1, UniConvertor, and other open-source tools.

Frequently Asked Questions

Why convert ARW to SK?

Vector formats like SK offer infinite scalability. Converting from Sony ARW creates a scalable version suitable for design and illustration contexts.

What programs open SK?

Open SK with Skencil (formerly Sketch) on Linux and compatible vector editors — it works across platforms.

Does the conversion preserve image quality?

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

What happens to my uploaded ARW images?

Your Sony ARW images are deleted right after conversion. The resulting SK output is removed from servers within 24 hours for complete privacy.

Is ARW to SK conversion free on Convertio?

Standard ARW to SK conversions are free on convertio.tools. Larger volumes or bigger images may benefit from a premium account for faster processing.
