What Translate PDF does
Translate PDF extracts the text from your document and uses an AI language model to translate it into another language, so you can understand a foreign-language PDF or prepare a draft translation of your own. It supports nearly 40 languages, including English, Chinese, Spanish, French, German, Japanese, Korean, Arabic, Hindi, and Russian, and can detect the source language automatically.
What you get back
You get the translated text on screen, which you can copy, download as a .txt file, or download as a new PDF. The PDF is typeset afresh in a simple layout, using a suitable embedded font and right-to-left layout for target languages such as Arabic. It does not reproduce the original page layout, images, columns, tables, or fonts, so think of it as a translation of the content, not a translated copy of the design.
Where your text goes, and the limits
Your browser extracts the text; only that text — not the PDF file — is sent to our server and then to an AI model for translation. PDF Studio does not keep a copy, but the AI service processes the text, so avoid translating information you must not share with a third party. Each tool allows 10 requests per minute per visitor.
About the first 28,000 characters of text (roughly 4,500 words) are translated per run. For longer documents, split the PDF into parts with Split PDF and translate each part. Scanned PDFs have no text, so run OCR PDF first.
Using machine translation responsibly
AI translation is fast and usually good for understanding the gist, but it can mistranslate idioms, names, numbers, and specialist terms, and occasionally omit sentences. For contracts, legal filings, medical information, or anything official, have a qualified human translator check or produce the final version.
