XLIFF to RESX
Converting a .xliff font to .resx repackages the same glyphs and metrics for a different delivery target. Free, private, and validated — the file never leaves your browser.

Converting a .xliff font to .resx 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 .resx file is a .NET XML resource file: a list of named data elements, each holding a value and an optional comment, used for the translatable strings and embedded assets of a .NET application. Visual Studio compiles it into a binary .resources file that is embedded in the assembly. For this route the practical draw is first-class in the .NET toolchain with designer support and compile-time accessors and can carry binary assets alongside strings, keeping a UI's resources together — balanced against extremely verbose — the schema preamble often outweighs the content, which is worth knowing before you commit a large batch.
Why convert XLIFF to RESX?
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 .resx buys you first-class in the .NET toolchain with designer support and compile-time accessors, which is why it is the better fit for localising a WinForms, WPF, ASP.NET or MAUI application. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
XLIFF vs RESX at a glance
| Aspect | XLIFF 2.0 (.xliff) | .NET RESX resources (.resx) |
|---|---|---|
| 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 document root is a plain <root> element; each entry is a <data name=…> containing <value> and optionally <comment> |
| Strongest at | interchange with tooling built against the 2.0 core | localising a WinForms, WPF, ASP.NET or MAUI application |
| Weak spot | less widely supported than 1.2 despite being the newer standard | extremely verbose — the schema preamble often outweighs the content |
| 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 | entry names, values and comments are preserved. The schema preamble, resheader declarations and base64 binary resources are not represented in string-catalog targets, and the culture — which lives in the filename — is not part of the document at all |
Pick RESX as the output
Select .resx in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if RESX 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 RESX file. Outputs keep the original filename with the .resx extension.
XLIFF to RESX questions, answered
Will converting XLIFF to RESX lose quality?
There is no visual quality to lose — xliff is text-oriented and resx 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 RESX file work?
Visual Studio, Rider and the .NET SDK read RESX natively, and the major translation platforms support it. Anything outside the .NET world generally does not. Novus Convert reads the data/value/comment structure locally, refuses documents declaring a doctype or custom entities, and converts to and from the other localization formats; binary base64 resources are outside the string-catalog model and are not carried across.
Will the RESX file be bigger or smaller than my XLIFF?
It depends on the content: the document root is a plain <root> element; each entry is a <data name=…> containing <value> and optionally <comment>. 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 RESX back to XLIFF?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .xliff → .resx → .xliff is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
