About formats

HEIF (High Efficiency Image File Format) is a container format for images and image sequences standardized by the Moving Picture Experts Group as ISO/IEC 23008-12, first published in 2015. HEIF is built on the ISO Base Media File Format (ISOBMFF, the same container used for MP4 video), providing a flexible structure that can hold single images, image collections, image sequences (like animations or bursts), and derived images with non-destructive editing operations. The container is codec-agnostic — while the most common implementation pairs HEIF with HEVC/H.265 compression (branded as HEIC by Apple), the standard also accommodates AV1 compression (creating the AVIF variant), H.266/VVC, and other future codecs. HEIF supports features that JPEG lacks: 10-bit and 12-bit color depth, wide color gamuts (Display P3, BT.2020), lossless compression, alpha transparency, depth maps, thumbnail images, and Exif/XMP metadata — all within a single file. Auxiliary image items can store computational photography data like depth maps, HDR gain maps, and semantic segmentation masks. One advantage is the format's future-proof architecture: by separating the container from the codec, HEIF can adopt newer, more efficient compression technologies without changing the file structure, metadata handling, or application-level APIs. The substantial compression improvement over JPEG is another core strength — HEVC-based HEIF typically achieves 40-50% file size reduction compared to JPEG at the same visual quality, beneficial for storage and bandwidth. HEIF is supported by Apple's ecosystem (iOS, macOS), Windows 10/11, Android 10+, GIMP, ImageMagick, and Adobe products.
Initial release: 2015
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 should I convert HEIF to SXW?

Transform your HEIF images into SXW documents for easy distribution — recipients can view the converted photo without needing RAW-compatible image editors.

What programs open SXW files?

SXW files can be opened with LibreOffice Writer, OpenOffice Writer, and StarOffice (legacy).

Do I need to install software?

No software needed. The conversion engine runs server-side — you just upload your HEIF through the browser and get the SXW back.

Is HEIF to SXW conversion free?

Standard HEIF to SXW conversions are free on Convertio. Premium plans unlock higher limits and faster queue priority for larger workloads.

Does the converter work on all devices?

Convertio works on any device with a web browser — desktop computers, laptops, tablets, and phones across all operating systems.

Does converting HEIF to SXW affect quality?

Your HEIF image data is processed carefully during conversion. The resulting SXW retains the maximum quality the target format can support.
