Will my PDF layout be preserved after translation?

What is the maximum PDF file size I can translate?

You can upload PDF files up to 300MB. For very large files, our system processes them in sections for optimal translation quality.

Can BookTranslator translate text inside PDF images?

Can I try PDF translation for free?

What format is the translated PDF output?

The output is a standard PDF file that can be opened in any PDF reader. You can also get a bilingual version with original and translated text side by side.

Which languages can I translate PDF files to?

BookTranslator supports translating PDF files to over 170 languages including Chinese (Simplified & Traditional), Spanish, French, German, Japanese, Korean, Arabic, Portuguese, Russian, Hindi, Thai, Vietnamese, Indonesian, Turkish, Polish, Dutch, Swedish, and many more.

How accurate is PDF translation to Chinese, Japanese, and Korean?

Our AI translation engine delivers high-quality translations for CJK (Chinese, Japanese, Korean) languages. The engine understands context, preserves formatting, and handles complex character sets natively. For PDF files, CJK translations maintain the original layout while adapting text direction and spacing for optimal readability.

Do I need to create an account to translate a PDF?

No account is required to pay per task. Create or log in to an account when you want to buy or use credits, keep a longer translation history, or subscribe to Pro.

Can I translate a password-protected or encrypted PDF?

Password-protected PDFs cannot be translated directly. You'll need to remove the password protection first using your PDF editor, then upload the unprotected file. This is a security measure. We cannot and do not attempt to bypass document encryption.

Who owns the translated PDF file?

You retain full ownership of both the original and translated PDF files. BookTranslator does not claim any rights to your content or translations. The translated file is yours to use as you see fit.

Can I translate PDFs with right-to-left languages like Arabic and Hebrew?

Yes. BookTranslator fully supports right-to-left (RTL) languages including Arabic, Hebrew, Farsi, and Urdu. The translation engine handles bidirectional text correctly, and the output preserves proper RTL text direction and layout within the PDF.

Can I get a bilingual PDF with both original and translated text?

Yes! BookTranslator supports bilingual output for PDF translations. You'll receive a document with alternating pages, with each source page followed by its translated version, making it easy to compare original and translation side by side.

Will my PDF content be used to train AI models?

No. Your uploaded PDFs and translated content are never used to train AI models. Your content is processed temporarily for translation only and is never stored, shared, or used for any other purpose.

Is the PDF translation quality good enough for professional use?

BookTranslator uses advanced AI models that understand context across paragraphs, preserving meaning and tone. For business documents, academic papers, and personal use, the quality is excellent. For professional publishing, we recommend reviewing the output for domain-specific nuances.
