FAQ
Frequently asked questions
Everything you need to know about translating PDFs online.
Is this PDF translator really free?+
Yes. Translating PDFs is 100% free, with no signup, no credit card, no watermark, and no daily limits. Documents are limited to 15 pages and 50 MB to keep the service fast for everyone.
Are there any hidden costs or restrictions?+
There are no hidden conditions. Files are limited to 15 pages so processing stays fast and the underlying API costs stay manageable. If a paid tier for larger documents is added in the future, this free version will remain free.
Do I need to sign up or download anything?+
No. Open the page, upload a PDF, select a target language, and view the translation next to the original. Everything runs in your browser. Nothing needs to be installed.
How do I translate a PDF document?+
Upload your PDF above, choose the source and target languages, and click Translate. Each page of the translation appears next to the original.
What languages are supported?+
More than 40 languages, including English, Spanish, French, German, Italian, Portuguese, Russian, Chinese (Simplified and Traditional), Japanese, Korean, Arabic, Hindi, Marathi, Bengali, Tamil, Telugu, Turkish, Dutch, Polish, Czech, and Ukrainian.
Will the formatting be preserved?+
Yes. Headings, bold, italic, and paragraph breaks from the original are detected and re-applied to the translated text, so the structure remains intact.
Can I translate scanned PDFs?+
Yes. For scanned PDFs, OCR (text recognition) runs in your browser before translation. This takes longer than for text-based PDFs, but it remains free.
How accurate are the translations?+
Translations are produced by a large language model (GPT) that provides high-quality, context-aware output. For legal, medical, or other critical documents, human review is recommended.
Are my files stored anywhere?+
No. PDFs are processed in your browser. Only the extracted text is sent for translation, and nothing is stored on the server after the request completes.
Can I translate password-protected PDFs?+
Not directly. The password must be removed first using a tool such as Adobe Acrobat. Then the unlocked file can be uploaded.
