How to Translate a PDF Online

Learn how to translate a PDF online with DodoPDF. Translate PDF documents into 100+ languages while preserving formatting, tables, images, and layouts. Supports OCR and scanned PDFs.

PDF files are commonly used for business documents, research papers, contracts, manuals, reports, and ebooks. When a PDF is written in another language, translating it can be difficult—especially if the document contains tables, images, charts, or complex formatting.

With DodoPDF, you can use an AI PDF translator to translate PDF documents online while preserving the original layout and structure.

What Is PDF Translation?

PDF translation means converting the text inside a PDF document from one language to another. Unlike simple text translation, PDF translation should also keep the document formatting, page layout, images, tables, and structure.

How to Translate a PDF Online

Step 1: Upload Your PDF File

Open the Translate PDF Online tool and upload your PDF document.

Step 2: Choose Your Target Language

Select the language you want to translate your PDF into, such as English, Thai, Spanish, French, or Japanese.

Step 3: Start the Translation

DodoPDF automatically detects the source language and translates your PDF while preserving paragraphs, tables, images, charts, headings, and document structure.

Step 4: Download the Translated PDF

Once the translation is complete, download your translated PDF and review the result.

Translate Scanned PDFs with OCR

Some PDF files are scanned images instead of selectable text. OCR technology helps recognize text inside scanned PDFs before translation, making it possible to translate scanned books, contracts, certificates, forms, and archived documents.

For scanned documents, try the Translate Scanned PDF tool.
