Localizing an app means living inside XLIFF files for days, and a heavy editor makes that work drag. Xliff Editor from SweetP Productions takes the opposite route. The app is tiny, opens fast and uses very little memory, yet it handles the jobs translators face. Its custom XML parser reads complex XLIFF 1.2 and 2.0 files, plus SDLXLIFF, XLZ and Xcode XLOC packages. Inline tags stay protected while you type, and translation memory keeps repeated phrases consistent.

FAQs

Which file formats can Xliff Editor open?

It opens XLIFF 1.2 and 2.0 files and also reads SDLXLIFF, XLZ and Xcode XLOC packages from development and translation tools.

Does it protect code tags while I translate?

Yes. Inline elements are protected in the editor, so placeholders and formatting tags stay intact while you work on the visible text around them.

Can it help with repeated phrases across projects?

Yes. Translation memory can be imported and exported, so approved translations can be reused and kept consistent in new files.
