About formats

ORF (Olympus RAW Format) is the proprietary RAW image format used by Olympus (now OM Digital Solutions) digital cameras, introduced in 2000 with the E-10 digital SLR and continuing through the entire Micro Four Thirds OM-D and PEN lineups. ORF files capture the unprocessed 12-bit or 14-bit readout from the camera's Four Thirds or Micro Four Thirds Live MOS or CCD sensor, preserving the complete Bayer-pattern mosaic data before any demosaicing, noise reduction, or color processing. The format uses an Olympus-specific container that stores the raw data with lossless compression alongside multiple embedded JPEG previews, extensive EXIF metadata, and Olympus MakerNote tags encoding Art Filter settings, in-body image stabilization parameters, face/eye detection results, and computational photography mode information. ORF has evolved across several generations of Olympus sensors, from the original 4-megapixel Four Thirds CCD to the 20+ megapixel stacked sensors in current OM System bodies, and the format has accommodated these changes while maintaining backward compatibility in processing software. One advantage is the Micro Four Thirds system's depth-of-field characteristics: ORF files from these smaller sensors deliver greater depth of field at equivalent apertures compared to full-frame, a genuine advantage for macro, landscape, and travel photography where sharpness throughout the frame matters. Wide processing support is another strength — ORF files are handled by Adobe Lightroom, Capture One, DxO, Olympus/OM Workspace, dcraw, and RawTherapee.

Initial release: 2000
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 ORF to SK?

Vector formats like SK offer infinite scalability. Converting from Olympus ORF 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.

How long does the conversion take?

Most ORF to SK conversions finish in seconds. Processing time depends on image resolution and server load, but results are typically fast.

Will my ORF metadata (EXIF) be preserved?

Metadata handling depends on the target format. Where SK supports it, camera data like shooting parameters and GPS coordinates can be retained.

Is ORF to SK conversion free on Convertio?

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