Website & Software Localization
End-to-end localization of websites, web apps, mobile apps, and SaaS platforms — UI strings, SEO metadata, marketing content, and multimedia.
Expanding into new markets means more than translating words — it means making your website, app, or software feel native to every user. A poorly localized interface frustrates visitors, kills conversions, and damages your brand. At iTrex, we provide end-to-end localization that goes beyond translation to address cultural nuances, UI constraints, and local SEO — so your digital product performs as well abroad as it does at home.
With over 20 years of experience and a team of 5,000+ linguists covering 120+ languages, we have localized everything from enterprise SaaS platforms and e-commerce websites to mobile apps and video games. Our engineers work directly with your development team, integrating seamlessly into CI/CD pipelines and supporting all major file formats — JSON, XLIFF, PO, YAML, Android XML, iOS Strings, and more.
Whether you are launching a single-language landing page or rolling out a 30-language platform, our ISO 9001-certified process ensures terminological consistency, brand voice preservation, and pixel-perfect UI across every locale.

What Our Clients Say
We localized our SaaS platform into 12 languages with iTrex, including UI strings, help documentation, and API error messages. They worked natively with our .json and .xliff files, which meant no reformatting on our end and a smooth integration with our CI/CD pipeline.
iTrex translated 1,200 pages of technical manuals for our robotic welding systems from Japanese into English, German, and Korean. The translators understood engineering diagrams, safety standards references, and maintained consistent terminology across all three target languages.
iTrex has been our translation partner for two years, handling proposals, pitch decks, and product specifications in nine languages. What I appreciate most is their consistency — the same terminology and tone across every document, even when we request fast turnarounds for trade shows.
