Google Translate is a free translation service supporting over 130 languages across text, voice, images, and documents.
About
Google Translate lets you translate typed text, spoken words, photos, and entire documents across more than 130 languages, with results available instantly on the web or through its mobile app. The conversation mode translates back-and-forth speech in real time, useful for face-to-face exchanges across language barriers. A camera mode handles menus, signs, and printed text using your phone camera. The core consumer service is free; businesses that need high-volume translation through an API use Google Cloud Translation, which is priced per character beyond a free monthly quota.
