Best Translation Agencies Compared

What Services Do Translation Companies Offer?

Most international translation agencies offer a wide variety of services related to converting source material from one language to another.

Most commonly, this is written material like technical documentation, articles, website copy, in-app text, etc. Some language translation companies also offer video translation services, which typically include subtitling, dubbing, and voice-over. 

However, it’s not uncommon for translation agencies to also offer multilingual content creation, as well as interpretation services. 

Here’s a quick rundown of the most common services the best translation agencies offer.

Document Translations

Translating documents typically involves understanding the context, industry-specific terminology, and cultural nuances of both languages to accurately convey the message in the target language. 

The best translation agencies have experienced linguists who specialize in particular fields, such as healthcare, finance, and legal.

This ensures accurate translations that heavily rely on context to ensure that the translation sounds native without changing the meaning or intent behind industry-specific and technical terms. 

Localization

Localization is the process of translating entire platforms, websites, or applications into a variety of different languages.

This is typically used by international companies that want to make their services more accessible to a global audience by ensuring that the website/app navigation and content are adapted to the user’s native language. 

Editing & Proofreading

A lot of stuff can get lost in translation, including words, punctuation, context, and even the original meaning. The best translation agencies employ professional editors to double-check both the original text and the translation.

They ensure there are no typos and that both texts are factually and grammatically correct, as well as that the translation is properly adapted to the target language and accurately conveys the original message. 

Interpreting

Interpreting refers to translating speech in real-time.

This service is most commonly used by government organizations when meeting foreign dignitaries, as well as global businesses during international conferences.

Other uses for interpreting include everything from healthcare and legal proceedings to travel and event production. 

Dubbing, Voice-Over, and Subtitling

The best translation agencies have state-of-the-art studios with modern equipment that allows them to translate, dub, or subtitle videos.

This service is indispensable for the entertainment industry since it’s essential to make TV shows and movies accessible to a wider audience.

Professional voice actors can record lines in a variety of different languages, while another team of linguists can add subtitles and sync them with the video. 

Conclusion — What is the Best Translation Agency in 2023?

When choosing a translation agency, you have to consider the types of services different agencies offer, translation agency rates, and the industries they specialize in.

There’s a huge difference between traditional document translation companies and agencies that offer machine translation, on-site interpreting, and content creation. 

In other words, no translation agency is objectively the best. It all comes down to finding a translation agency that best aligns with the needs of your business. 

That said, our top overall pick is RWS. This translation agency has a hugely impressive client portfolio, and it offers everything from translation and interpreting to content creation and AI-powered multilingual content processing.
