About formats

JP2 (JPEG 2000 Part 1) is an image format based on the JPEG 2000 compression standard, developed by the Joint Photographic Experts Group and published as ISO/IEC 15444-1 in December 2000 as the successor to the original JPEG standard. Unlike JPEG's block-based discrete cosine transform, JPEG 2000 uses discrete wavelet transform (DWT) compression, which eliminates the characteristic 8x8 block artifacts visible in highly compressed JPEG images and instead produces a smooth, gradual quality degradation. The format supports both lossy and lossless compression within the same codestream, along with features absent from original JPEG: 16-bit and higher bit-depth images, arbitrary numbers of color channels, alpha transparency, region-of-interest coding (allocating more bits to important areas), and progressive quality or resolution refinement from a single compressed stream. One advantage is superior image quality at low bit rates — JPEG 2000 produces visibly cleaner images than JPEG at equivalent file sizes, particularly below 0.5 bits per pixel where JPEG exhibits severe blocking. The progressive decoding capability is another strength: a single JP2 file can be decoded at any resolution or quality level without encoding multiple versions, valuable for remote sensing and medical imaging where the same image must serve both thumbnail browsing and full-resolution analysis. JP2 is the mandated format for digital cinema (DCI), the preferred format in geospatial data (GeoJP2), and widely adopted in cultural heritage digitization.
Initial release: December 2000
SXW is the word processing document format used by StarOffice 6.0 and OpenOffice.org 1.0, developed by Sun Microsystems and released in 2002. The format was one of the first mainstream office document formats to adopt an XML-based architecture, packaging document content, styles, metadata, and embedded media in a ZIP archive — a structural approach that directly influenced the later OpenDocument Format (ODF). The content.xml file describes the document body using XML elements for paragraphs, headings, lists, tables, footnotes, and inline formatting, while styles.xml defines the styling rules and meta.xml carries document properties. SXW represented a significant milestone in open-source office software, demonstrating that a non-proprietary XML format could handle the full range of word processing features including change tracking, indexes, cross-references, and complex page layouts. One advantage was transparency and openness — the XML structure made document content inspectable, transformable, and processable using standard tools, a sharp contrast to the opaque binary formats dominant at the time. The format's role as a technological precursor to the ODF standard is another historical significance: the OASIS OpenDocument Technical Committee used the OpenOffice.org XML format (including SXW) as the starting point for developing ODF 1.0. While SXW was superseded by ODT with OpenOffice.org 2.0 in 2005, existing SXW documents can be opened by LibreOffice, Apache OpenOffice, and document conversion tools.

Frequently Asked Questions

Why convert JP2 to SXW?

Moving from JP2 to SXW creates a document container for your image — ideal for professional workflows that require editable, shareable formats.

What software opens SXW?

Applications like OpenOffice Writer, LibreOffice Writer all support SXW. Check your system — a compatible viewer may already be installed.

Is JP2 to SXW conversion free?

Standard conversions are free on Convertio. For larger volumes or bigger images, premium plans offer expanded limits and faster processing queues.

Is my data safe during conversion?

Uploaded images are deleted right after conversion, and output files are removed within 24 hours. Your data stays private throughout the process.

Is the conversion lossless?

The conversion retains image quality within the capabilities of SXW. Any format-specific limitations are inherent to the target, not the conversion process.

What platforms does this converter support?

The converter works on any device with a browser — Windows, macOS, Linux, iOS, and Android. No app installation needed — everything runs in the cloud.
