XLIFF: the Professional Standard for Localization

XLIFF (XML Localization Interchange File Format) is an ISO standard designed specifically for the exchange of localizable content between authoring systems and translation tools. Every translatable string is stored as a discrete segment with a unique ID, enabling translation memory tools to match, reuse, and apply previously translated content at the segment level.

We process XLIFF 1.2 and XLIFF 2.0 files using professional translation memory tools. Segment status markers (translated, reviewed, final) are respected and updated in the delivered file. State attributes are correctly set on all target segments. If your CMS, app build system, or CAT tool exports XLIFF, this is the most effective format for ongoing localization projects.

XLIFF is a localization exchange format, not an official one. If legal text inside the file, such as terms of service, must be documented for a state court, we can deliver that text separately as a certified translation with a signed certificate of accuracy. Localization kickoffs and review meetings with international teams can be supported by expert interpretation services.

What You Get

Key Features of XLIFF File Translation

Translation Memory Reuse

Segments are matched against your project TM at the 100%, fuzzy, and no-match levels. Reused segments reduce cost and delivery time on every subsequent project.

Segment State Management

XLIFF state attributes (needs-translation, translated, reviewed, final) are correctly set on all delivered segments. Your CMS import workflow receives the status it expects.

QA and Validation

Segment-level QA checks including tag verification, length limits, terminology consistency, and number format validation are run before delivery.

XLIFF 1.2 and 2.0 Support

Both the widely deployed XLIFF 1.2 format and the newer XLIFF 2.0 standard are supported natively, including XLIFF extensions used by major CMS and app platforms.

Questions About XLIFF Translation

What Is the Difference Between XLIFF 1.2 and XLIFF 2.0?
XLIFF 1.2 is the version most widely supported by current CMS platforms, translation management systems, and CAT tools. XLIFF 2.0 is the current ISO standard and introduces a modular architecture that is more extensible. We support both versions. If you are unsure which version your platform exports, send us a sample file and we will identify it.
Can You Integrate with Our Localization Platform or CMS Directly?
XLIFF exchange is the standard integration method for localization platforms. If your platform supports XLIFF export and import, our workflow is directly compatible. For enterprise projects requiring API-based integration or direct TMS connector setup, contact us to discuss the options.
How Are Inline Tags and Placeholders Handled in XLIFF Files?
XLIFF inline elements such as ph, g, x, bx, and ex tags wrap non-translatable content within segments. These are preserved exactly in the translated segment and are never translated. Our QA validation verifies that every inline tag in the source segment appears correctly in the target segment.
