About formats

DOCX is the default document format for Microsoft Word since Office 2007, based on the Office Open XML (OOXML) standard published as ECMA-376 and adopted as ISO/IEC 29500. A DOCX file is a ZIP archive containing XML documents that describe the document body (document.xml), styles, themes, headers, footers, footnotes, comments, numbering definitions, and relationships between parts. Media assets like images and embedded objects reside in dedicated directories within the package. The XML structure means document content is human-inspectable and programmable — developers can create, modify, and extract content from DOCX files using standard XML libraries in any programming language without requiring Word. One significant advantage is openness and interoperability: the published specification enables any software to implement DOCX support, and the format is read and written by LibreOffice, Google Docs, Apple Pages, and dozens of other tools across all platforms. Built-in ZIP compression is another practical strength — DOCX files are substantially smaller than equivalent DOC files, and the modular XML structure improves crash recovery since corruption in one part does not necessarily destroy the entire document. The format supports all modern Word capabilities including SmartArt, content controls, bibliography management, accessibility metadata, and real-time co-authoring. DOCX has become the universal standard for document interchange in business, education, and government.

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.

Frequently Asked Questions

Why convert DOCX to HEIF?

HEIF is a modern image container with excellent compression — converting DOCX pages to HEIF produces high-quality, space-efficient images for Apple and modern devices.

What opens HEIF files?

Apple Photos and Preview open HEIF natively. On Windows, HEIF support is available through Microsoft Store extensions. GIMP also handles HEIF.

How is HEIF different from HEIC?

HEIF is the format specification; HEIC is a specific HEIF profile using HEVC compression. In practice, they are nearly interchangeable on Apple devices.

Will my document formatting be preserved?

Each page is rendered as a pixel-accurate image — fonts, layout, tables, and embedded graphics are all captured in the HEIF output.

Is this service free?

DOCX to HEIF conversion is free on Convertio. Paid plans offer expanded capacity for power users.
