Software Localization: A Key to International Success in 2026
Professional translation by native-level linguists in 120+ languages
Software localization is the process of adapting an app, website or platform so it feels native to users in another market – not just translated. It covers the interface text, right-to-left layouts, dates, currencies, help content and cultural details. For companies targeting Egypt, the Gulf or markets abroad, good localization improves adoption, reviews and conversions. This guide explains what localization involves and how to plan it.
Translation vs. localization vs. internationalization
| Term | Meaning |
|---|---|
| Internationalization (i18n) | Engineering the software so it can support any language: externalised strings, Unicode, flexible layouts |
| Translation | Converting text from one language to another |
| Localization (l10n) | Adapting the whole product for a market: language, formats, images, legal text, tone |
Internationalization comes first. If strings are hard-coded or layouts cannot expand, localization becomes slow and expensive.
What gets localized
- User interface: menus, buttons, error messages and notifications.
- Formats: dates, times, numbers, currencies, addresses and phone numbers.
- Layout: right-to-left support for Arabic, text expansion for German or French.
- Content: onboarding, help centre, FAQs, emails and app-store listings.
- Legal text: terms of service and privacy policies, translated carefully – see what is legal translation?
- Culture: images, colours, examples, humour and forms of address.
Special challenges of Arabic localization
- Right-to-left (RTL): the whole interface must mirror, including icons that imply direction, while numbers and Latin product names still read left to right.
- Grammar: Arabic changes words for gender and number (singular, dual and plural), so placeholders like "{count} files" need proper plural rules.
- Register: choose between Modern Standard Arabic and a lighter, more conversational tone depending on your brand and audience.
- Fonts: pick Arabic fonts that render clearly at small sizes on mobile screens.

A practical localization process
- Prepare: export strings in a standard format (JSON, XLIFF, PO, RESX) with context notes and screenshots.
- Glossary and style guide: agree on key terms, product names that stay in English and tone of voice.
- Translate with linguists who understand software and the target market.
- Review in context – a second linguist checks the strings inside the running app.
- Test: look for truncated text, broken RTL layouts and wrong formats.
- Maintain: send new strings with every release so the product never goes out half-translated.
Machine translation can speed up first drafts, but it needs professional post-editing for user-facing text – see proofreading, editing and MTPE.
Business benefits
Localized products are easier to use, generate fewer support tickets and build trust. Localized app-store listings and websites also help users find you in local searches. For websites specifically, see our website localization service.
Frequently asked questions
When should we start localizing?
As early as possible. Internationalizing the code during development is far cheaper than retrofitting it later, and it lets you launch several languages at the same time instead of one by one.
Which file formats can you work with?
Common string formats such as JSON, XLIFF, PO, RESX, Android XML and iOS strings, as well as Excel exports.
How do you handle placeholders and code?
Our linguists keep placeholders, tags and variables untouched and flag strings that need plural or gender handling.
Can you localize into languages other than Arabic?
Yes. We work in more than 120 languages, including major European and Asian languages.
