What is the XLIFF file format and how does Pairaphrase support it?

What is XLIFF?

XLIFF (XML Localization Interchange File Format) is an open standard developed by OASIS. It’s designed to enable the exchange of translatable data between content creation tools and translation software, ensuring compatibility and consistency across platforms.

XLIFF is widely used in:

• Software and app localization

• eLearning content development (e.g., Articulate, Adobe Captivate)

• Web and product documentation

• Corporate training programs

XLIFF Support in Pairaphrase

Pairaphrase supports both XLIFF 1.2 and XLIFF 2.0. You can:

• Upload XLIFF files for instant translation

• Edit and post-edit using the Translation Editor

• Export the translated XLIFF file for use in your authoring tool or CMS

Important: Compatibility Alert for DeepL and XLIFF 1.2

Our development team has investigated recent issues reported with XLIFF translations and confirmed that XLIFF 1.2 files may cause errors when translated using the DeepL engine. Common symptoms include:

• Empty target segments

• Mistranslations

• Broken formatting or placeholder tags

To avoid these issues, we strongly recommend the following:

Export XLIFF files in version 2.0

If you're using tools like Articulate, choose to export your files directly in XLIFF 2.0 format. This format offers better segmentation, clearer structure, and improved compatibility with modern translation engines like DeepL.

How to check your XLIFF version

Open your file in Notepad++ (or any code editor) and inspect the first line of the XML code. It will show the version, e.g.:

or

If you see version 1.2 and plan to use DeepL, consider re-exporting the file from your authoring tool in 2.0 format if supported.
