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.

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 HEIF to ODT?

HEIF stores raw image data — converting to ODT creates a portable document version that can be embedded in reports, presentations, or shared via email.

What programs open ODT files?

Open ODT files using LibreOffice Writer, Google Docs, Microsoft Word, and Calligra Words.

Does converting HEIF to ODT affect quality?

The conversion preserves visual quality as closely as the target format allows. ODT output maintains the essential detail from your original HEIF image.

Is my HEIF file safe during conversion?

Your files are handled securely. The HEIF upload is erased right after processing, and the resulting ODT is purged from servers within 24 hours.

Can I convert multiple HEIF files to ODT at once?

Absolutely — Convertio lets you upload multiple HEIF files simultaneously. Each is converted to ODT and available for individual download.

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 ODT back.
