Add your STRINGS file
Drop one or more .strings 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 .strings font to .pot 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 .strings font to .pot repackages the same glyphs and metrics for a different delivery target. A .strings file is Apple's localization resource: a flat list of "key" = "value"; statements, one per translatable string, usually named Localizable.strings and stored inside a per-language .lproj directory. It is what NSLocalizedString and its SwiftUI equivalents look up at runtime.
A .pot file is a gettext Portable Object Template: the same grammar as a .po file, but with every msgstr deliberately empty. It is the extraction output — the list of every translatable string found in a codebase — from which each language's .po file is created and later merged. For this route the practical draw is one canonical source of truth for what is translatable and carries source references, so a string can be traced back to the line that produced it — balanced against contains no translations, so it is easy to mistake an empty catalog for a broken one, which is worth knowing before you commit a large batch.
The practical trigger for this conversion is usually a mismatch: with .strings, no plural support at all — that requires a second file in a different format. Switching to .pot buys you one canonical source of truth for what is translatable, which is why it is the better fit for handing a complete string inventory to translators or a translation vendor. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
| Aspect | Apple strings localization (.strings) | GNU gettext template (.pot) |
|---|---|---|
| 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 | each entry is `"key" = "value";` — the trailing semicolon is required, and both sides use C-style escapes | syntactically identical to .po; the difference is semantic — msgstr values are empty by definition |
| Strongest at | localising an existing iOS, iPadOS or macOS application | handing a complete string inventory to translators or a translation vendor |
| Weak spot | no plural support at all — that requires a second file in a different format | contains no translations, so it is easy to mistake an empty catalog for a broken one |
| Metadata | keys and translated values are preserved. Comments are not treated as structured notes, and plural rules cannot be represented — a catalog with plurals converted into .strings will lose the plural forms because the format has no way to hold them | identifiers, source strings and context survive. Empty targets are preserved as empty rather than being filled from the source. Header placeholders and source references are not carried into formats with no equivalent field |

Select .pot in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if POT 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 POT file. Outputs keep the original filename with the .pot extension.
There is no visual quality to lose — strings is text-oriented and pot 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 .strings 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.
Any tool that reads .po reads .pot, since the grammar is the same. Novus Convert converts templates to and from the other localization formats and preserves the empty-target semantics — a template converted to XLIFF arrives with empty targets rather than targets echoing the source, which is what makes it still usable as a template.
It depends on the content: syntactically identical to .po; the difference is semantic — msgstr values are empty by definition. Convert one representative file first and compare before batch-processing a large set.
In .strings, keys and translated values are preserved. Comments are not treated as structured notes, and plural rules cannot be represented — a catalog with plurals converted into .strings will lose the plural forms because the format has no way to hold them. 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 .strings → .pot → .strings is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
