Why not simply use machine translation instead of booking translation services?

There is no question that machine translation has improved dramatically in recent years, but it still falls far short of the nuances of human translators. For internal communication or initial drafts, machine translation can certainly be helpful. For customer-oriented content, legal documents or marketing materials, there is no way around professional translation and localization companies.

Good to know: Modern translation and localization companies optimally combine both approaches through post-editing processes.

What Is a Translation and Localization Company?

A translation company converts content from one language to another.
A localization company does far more.

It adjusts:

• cultural norms
• legal requirements
• measurements, units, dates, currencies
• tone of voice
• user expectations
• visual elements and UX

Translation makes text understandable.
Localization makes it feel native, natural, and persuasive.

Example:
A simple manual translation converts words.
Localization changes units, warnings, visuals, and legal references — everything needed to fit the target market perfectly.
