In the near future the gaming market will exceed USD 360 billion, and quality localization is key to global success. We’ve compiled the top 10 companies based on revenue, portfolio (MobyGames/ProZ), and reputation to help you navigate the market more easily.
The global video game market is growing rapidly: in the near future its volume will exceed USD 360 billion. Today, studios are not just creating games—they are creating global products. And to reach players around the world, translation alone is not enough.
Localization is not just about transferring text. It’s about adapting humor, cultural realities, UI, syllables, and intonations. It’s a way to make the game feel familiar—in any language. From small indies to large-scale AAA projects, competent localization directly affects success abroad.
Localization also significantly influences the understanding of the plot, the atmosphere, as well as player retention, which is one of the key tasks for developers and publishers.
In this article, we have compiled a list of the top 10 game localization companies in 2025 based on their reputation, revenue, portfolio, quality of services, and participation in well-known projects.

What to look for when choosing a localization studio?
Key Criteria
- Scale and specialization: Large LSPs are suitable for global, multi-platform, and AAA projects. Small ones are better for indie or mid-tier projects, where flexibility and a personalized approach are important. There are also universal companies, such as Allcorrect, that are flexible enough to work on projects of various scales.
- Services: Translation, LQA, voice acting, UI/art/marketing—important if the game is complex (dialogues, UI, voice acting, marketing).
- Stability and reliability: For major releases, global markets, and live games, it is better to choose companies with a proven reputation.
- Flexibility and speed: For indie, mobile, and live games, it is better to choose studios with quick response times, flexible workflows, and a willingness to work with patches.
