Translating a PDF is harder than translating a Word document because PDFs lock the text into a fixed layout. Pasting PDF text into Google Translate destroys the formatting. The right approach preserves both the translation accuracy and the original document layout — here is how.

How Accurate is AI PDF Translation?
For professional or technical documents (contracts, manuals, reports), AI translation is typically 90–95% accurate for major language pairs (English, Spanish, French, German, Portuguese, Italian, Japanese, Chinese, Korean). Accuracy is lower for: rare language pairs, highly technical or legal jargon, documents with cultural nuance, and colloquial language. For any document that will be used legally or clinically, have a human translator review the AI output. For internal use, research, or understanding a document's content, AI translation is more than sufficient.
Why Google Translate Breaks PDF Formatting
Google Translate accepts PDF files but typically returns the translated text in a plain layout that does not match the original. Tables collapse, multi-column layouts merge into single columns, and page numbering is lost. For documents where the layout matters (contracts with signature lines, forms with fields, reports with figures and captions), use an AI tool that can translate while preserving the structure, or use the PDF-to-Word conversion path and reformat as needed after translation.
