Add your XLIFF file
Drop one or more .xliff files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
Converting a .xliff font to .i18next repackages the same glyphs and metrics for a different delivery target. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Converting a .xliff font to .i18next repackages the same glyphs and metrics for a different delivery target. 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.
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. For this route the practical draw is plain JSON, so every tool in the JavaScript ecosystem already reads it and nesting keeps large catalogs navigable — balanced against no metadata at all — translators get keys and strings with no context, which is worth knowing before you commit a large batch.
The practical trigger for this conversion is usually a mismatch: with .xliff, less widely supported than 1.2 despite being the newer standard. Switching to .i18next buys you plain JSON, so every tool in the JavaScript ecosystem already reads it, which is why it is the better fit for localising a React, Vue, Angular or Node application. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
| Aspect | XLIFF 2.0 (.xliff) | i18next JSON (.i18next) |
|---|---|---|
| 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 | the root xliff element carries srcLang and trgLang, replacing 1.2's source-language and target-language on file | nesting is structural: objects group keys, and lookups use a dotted path with the separator configurable |
| Strongest at | interchange with tooling built against the 2.0 core | localising a React, Vue, Angular or Node application |
| Weak spot | less widely supported than 1.2 despite being the newer standard | no metadata at all — translators get keys and strings with no context |
| Metadata | 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 | 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 |

Select .i18next in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if I18NEXT is selectable, the route is real and validated.
Press Convert. The font tables are parsed and rewritten locally with fonteditor-core; glyph outlines, hinting, and kerning survive the trip.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid I18NEXT file. Outputs keep the original filename with the .i18next extension.
There is no visual quality to lose — xliff is text-oriented and i18next 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.
Yes — the .xliff 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.
Universally readable as JSON, and supported natively by i18next and every major translation platform. Novus Convert flattens nested objects into dotted keys locally — matching how the strings are addressed in code — and converts to and from the other localization formats.
It depends on the content: nesting is structural: objects group keys, and lookups use a dotted path with the separator configurable. Convert one representative file first and compare before batch-processing a large set.
In .xliff, 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. 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.
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .xliff → .i18next → .xliff is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
