Converting a .xliff font to .xlf 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.
A .xlf file is an XLIFF document — the OASIS XML standard for moving translation work between tools. Each translatable string becomes a trans-unit holding a source element and, once translated, a target element, wrapped in a file element that records the source and target languages. For this route the practical draw is a real published standard rather than a vendor convention and expresses review state and inline formatting that simpler formats cannot — balanced against verbose — several lines of markup per string, which is worth knowing before you commit a large batch.
Why convert XLIFF to XLF?
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 .xlf buys you a real published standard rather than a vendor convention, which is why it is the better fit for sending strings to a translation agency and getting reviewed work back. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
XLIFF vs XLF at a glance
| Aspect | XLIFF 2.0 (.xliff) | XLIFF 1.2 (.xlf) |
|---|---|---|
| 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 | the root xliff element declares a version; file elements carry source-language and target-language attributes |
| Strongest at | interchange with tooling built against the 2.0 core | sending strings to a translation agency and getting reviewed work back |
| Weak spot | less widely supported than 1.2 despite being the newer standard | verbose — several lines of markup per string |
| 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 | unit identifiers, source and target text and the declared source/target languages are preserved. Translation state, notes and inline placeholder markup are not carried into flat key-value formats, which have nowhere to record them |
Pick XLF as the output
Select .xlf in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if XLF 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 XLF file. Outputs keep the original filename with the .xlf extension.
XLIFF to XLF questions, answered
Will converting XLIFF to XLF lose quality?
There is no visual quality to lose — xliff is text-oriented and xlf 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 XLIFF files here?
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.
Where will the XLF file work?
Every serious translation management system reads XLIFF 1.2, and it is the safest common denominator for handing work to a vendor. Novus Convert reads both 1.2 trans-units and 2.0 units through one bounded parser, rejects documents carrying a doctype or custom entities outright, and converts to and from the other localization formats locally.
Will the XLF file be bigger or smaller than my XLIFF?
It depends on the content: the root xliff element declares a version; file elements carry source-language and target-language attributes. Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my XLIFF file?
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.
Can I convert XLF back to XLIFF?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .xliff → .xlf → .xliff is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
