Converting a .i18next font to .xliff repackages the same glyphs and metrics for a different delivery target. An i18next resource is the JSON translation file used by the i18next library: nested objects whose leaf values are the translated strings, addressed in code by dotted keys such as nav.settings.title. Because the file is ordinarily just named en.json, Novus Convert identifies it by the .i18next.json suffix so it is not mistaken for arbitrary JSON.
A .xliff file is an XLIFF document written with the long extension, most often at version 2.0 — the redesigned OASIS standard in which each translatable string is a unit containing one or more segments, each with its own source and target. The payload matches the .xlf form; the structure is what changed. For this route the practical draw is a much cleaner specification than 1.2, with a genuinely small mandatory core and modules make optional capability explicit instead of implied — balanced against less widely supported than 1.2 despite being the newer standard, which is worth knowing before you commit a large batch.
Why convert I18NEXT to XLIFF?
The practical trigger for this conversion is usually a mismatch: with .i18next, no metadata at all — translators get keys and strings with no context. Switching to .xliff buys you a much cleaner specification than 1.2, with a genuinely small mandatory core, which is why it is the better fit for interchange with tooling built against the 2.0 core. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
I18NEXT vs XLIFF at a glance
| Aspect | i18next JSON (.i18next) | XLIFF 2.0 (.xliff) |
|---|---|---|
| Format type | Text-based — characters and structure, so there is no visual quality loss | Text-based — characters and structure, so there is no visual quality loss |
| How it stores data | nesting is structural: objects group keys, and lookups use a dotted path with the separator configurable | the root xliff element carries srcLang and trgLang, replacing 1.2's source-language and target-language on file |
| Strongest at | localising a React, Vue, Angular or Node application | interchange with tooling built against the 2.0 core |
| Weak spot | no metadata at all — translators get keys and strings with no context | less widely supported than 1.2 despite being the newer standard |
| Metadata | dotted keys and their translated values are preserved. The format carries no descriptions or notes to lose; plural and context suffixes are treated as ordinary distinct keys, because they are exactly that in the file | unit identifiers, source and target text and the declared languages are preserved. Module data — change tracking, glossary entries, translation candidates — and inline markup are not represented in flat key-value targets |
Pick XLIFF as the output
Select .xliff in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if XLIFF is selectable, the route is real and validated.
Convert on your device
Press Convert. The font tables are parsed and rewritten locally with fonteditor-core; glyph outlines, hinting, and kerning survive the trip.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid XLIFF file. Outputs keep the original filename with the .xliff extension.
I18NEXT to XLIFF questions, answered
Will converting I18NEXT to XLIFF lose quality?
There is no visual quality to lose — i18next is text-oriented and xliff is text-oriented, so the question is structural fidelity. Text, ordering, and basic structure are preserved; complex layout, embedded objects, and styling beyond the target's model are simplified.
Is it private to convert I18NEXT files here?
Yes — the .i18next file is processed inside your browser tab and never uploaded. The font tables are parsed and rewritten locally with fonteditor-core; glyph outlines, hinting, and kerning survive the trip. Close the tab and the file is gone from memory.
Where will the XLIFF file work?
Support is good in modern translation management systems and patchier in older desktop tools, so 1.2 remains the safer choice when a recipient's capabilities are unknown. Novus Convert parses 2.0 units and segments alongside 1.2 trans-units, refuses documents with a doctype or custom entities, and converts locally to the other nine localization formats.
Will the XLIFF file be bigger or smaller than my I18NEXT?
It depends on the content: the root xliff element carries srcLang and trgLang, replacing 1.2's source-language and target-language on file. Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my I18NEXT file?
In .i18next, dotted keys and their translated values are preserved. The format carries no descriptions or notes to lose; plural and context suffixes are treated as ordinary distinct keys, because they are exactly that in the file. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
Can I convert XLIFF back to I18NEXT?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .i18next → .xliff → .i18next is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
