Google Cloud Translation is a developer API that translates text and DOCX, PPT and PDF documents in 189 languages. Document translation costs $0.08 per page sent; text has 500,000 free characters a month.
Google Cloud Translation is a pay-as-you-go API from Google Cloud for translating websites, apps, documents and media. The vendor says it covers 189 languages and offers pre-trained and custom models, plus an Adaptive Translation feature that uses Gemini and a small set of your own examples to match style and tone.
There are two editions. Basic is for short, casual or user-generated content, and Advanced adds domain-specific translation, formatted document translation and batch translation. Advanced can translate DOCX, PPT and PDF files while keeping their formatting, and a separate method handles XLSX files. The API is aimed at developers who build translation into an app or a workflow, and it is not a ready-made tool for uploading a file in a browser.
Pricing is by usage. The first 500,000 characters per month of text translation are free, applied as a monthly credit of up to $10 that does not roll over and does not apply to formatted document translation. Text translation with the standard model is $20 per million characters after that, with lower tiers at higher volumes. Document translation in DOCX, PPT and PDF is $0.08 per page sent to the API, falling to $0.072 and $0.064 at higher volumes. For batch jobs, the pages or characters are multiplied by the number of target languages. A translation large language model is priced at $10 per million input characters and $10 per million output characters.
