About formats

X3F is the proprietary RAW image format used by Sigma cameras equipped with Foveon X3 direct image sensors, introduced in 2002 with the Sigma SD9 — the first digital SLR camera to use a sensor that captures full color information at every pixel location. Unlike conventional cameras that use a Bayer color filter array (where each pixel records only one color and the other two are interpolated), the Foveon X3 sensor stacks three photodiode layers at each pixel site, exploiting silicon's wavelength-dependent absorption depth to capture blue, green, and red light simultaneously. X3F files therefore store a fundamentally different kind of raw data: three complete color planes captured at the same spatial location, with no demosaicing required. The format uses a proprietary container with multiple data sections including the raw sensor data (compressed using a Huffman-based scheme), embedded JPEG previews, camera metadata, and Sigma-specific processing parameters. One advantage is the absence of demosaicing artifacts: because every pixel records all three colors natively, X3F images exhibit a per-pixel sharpness and color accuracy that Bayer-based sensors achieve only after interpolation — there is no moire, no false color, and no loss of spatial resolution from the color reconstruction step. This produces a rendering quality that many photographers describe as uniquely three-dimensional and film-like, particularly at low ISO settings. X3F files can be processed using Sigma's Photo Pro software, and are also supported by dcraw, Iridient Developer, and other RAW converters.

ODT (OpenDocument Text) is the word processing format defined by the OpenDocument Format (ODF) standard, developed by the OASIS technical committee and first published as ODF 1.0 on May 1, 2005, later adopted as international standard ISO/IEC 26300. An ODT file is a ZIP archive containing XML documents that describe text content, formatting styles, metadata, and settings using a vendor-neutral, royalty-free specification. The document body resides in content.xml with styling rules in styles.xml, while embedded images, fonts, and other resources are stored alongside in the package. The format supports rich word processing features including paragraph and character styles, tables, footnotes, tracked changes, table of contents generation, bibliography management, mail merge fields, and embedded vector and raster graphics. ODT serves as the native format for LibreOffice Writer, Apache OpenOffice Writer, and Calligra Words, and can be imported by Microsoft Word, Google Docs, and other commercial tools. One advantage is vendor independence — ODT is governed by an open standard rather than a single company, ensuring long-term document accessibility free from proprietary lock-in. This makes ODT particularly important for government agencies, educational institutions, and organizations with archival mandates. The XML-based architecture provides another strength, enabling programmatic document generation and processing using standard tools in any programming language.

Frequently Asked Questions

Why convert X3F to ODT?

X3F is one of the most niche RAW formats — only Sigma cameras produce it, so converting to ODT is needed for broader use.

What opens ODT files?

ODT files can be opened with LibreOffice Writer, Apache OpenOffice, Google Docs, and Microsoft Word.

Does X3F to ODT work on Mac and Linux?

Convertio runs entirely in the browser — it works on Windows, macOS, Linux, and even mobile devices with no installs.

Is X3F to ODT conversion free on Convertio?

Standard conversions are available for free. Premium plans unlock higher capacity and priority processing for heavy use.
