How do I translate a PDF document?

Upload your PDF file, select the source and target languages, and our AI will translate the content while preserving the original formatting and layout.

How accurate is the translation?

Our AI-powered translation engine provides high-quality translations with context awareness, though we recommend human review for critical documents.

Can I translate large PDF files?

Yes, our tool handles PDF files up to 50MB. Larger documents may take longer to process but will maintain translation quality throughout.

Is my document content secure during translation?

Absolutely. All translations are processed securely and your documents are automatically deleted after processing. We never store or access your content.

Can I translate a PDF file for free?

Yes. PDFly's PDF translation tool is completely free to use. Upload your PDF, select a target language, and translate — no account or payment required.

How can I translate a protected PDF document?

If a PDF is password-protected, you need to unlock it first. Use PDFly's Unlock PDF tool to remove the password, then upload the unlocked file for translation.

Can I translate a scanned PDF file?

Yes. PDFly uses optical character recognition (OCR) to extract text from scanned PDFs before translating. Translation quality depends on the clarity of the scan.

Will the formatting stay the same after translation?

PDFly preserves the original document layout including fonts, tables, columns, and images. Complex multi-column layouts may require minor adjustments after translation.

Do I need to install software to translate a PDF?

No installation is required. The online PDF translator works directly in your browser — just upload your file and translate. A desktop app and browser extension are also available for offline use.
