PDF Translator — FAQ

                

                    
                    

                        

                            
                        

                        

                            
Upload a PDF and translate the full text into any of 99 target languages. Source language is auto-detected, output comes back as .txt or .docx with one paragraph per source paragraph. Best for documents where content matters more than layout.

                        

                    

                    
                    

                        

                            
                        

                        

                            
About 400 tokens per page, 600-token floor. A 20-page document costs ~8,000 tokens. The exact quote appears after upload — we call /v1/pdf/translate-quote/ with the real page count before you submit.

                        

                    

                    
                    

                        

                            
                        

                        

                            
99 target languages covering Europe (English, Spanish, French, German, Italian, Portuguese, Polish, Russian, Dutch, Swedish, Greek, Ukrainian, etc.), Asia (Chinese simplified + traditional, Japanese, Korean, Hindi, Bengali, Tamil, Thai, Vietnamese, Indonesian), Middle East (Arabic, Hebrew, Persian), and Africa (Swahili, Hausa, Yoruba, Zulu, Afrikaans, Amharic). Source auto-detect works across all of them.

                        

                    

                    
                    

                        

                            
                        

                        

                            
MadLAD-400, a 10B-parameter self-hosted open-source translation model with 450+ language pairs. Runs on our GPU4 — no third-party API, no data leaves our infrastructure. For comparison, DeepL supports 33 languages and Google Cloud Translate charges $20/M characters.

                        

                    

                    
                    

                        

                            
                        

                        

                            
Not yet. Layout-preserving PDF output (re-flow into the original pages) requires a layout analysis model we have not integrated. The .docx output preserves paragraph breaks and page boundaries so you can do a final layout pass in Word if needed.

                        

                    

                    
                    

                        

                            
                        

                        

                            
MadLAD needs extracted text. If the PDF is image-only, run /pdf/ocr/ first to get a text-layer PDF or .txt, then feed the result back into the translator. We auto-detect scanned PDFs on upload and link you to the right tool.

                        

                    

                    
                    

                        

                            
                        

                        

                            
We render one Word paragraph per source paragraph, with a page break at every original page boundary. Opens cleanly in Word, LibreOffice, Pages, Google Docs.

                        

                    

                    
                    

                        

                            
                        

                        

                            
50 MB per upload. Very long PDFs (200+ pages) are still supported — the translator iterates per page and takes ~3 seconds per page. The heavy-task banner appears automatically above 5 pages so you can close the tab and get an email when it finishes.

                        

                    

                    
                    

                        

                            
                        

                        

                            
Paragraph breaks and page boundaries yes. Bold/italic/tables/lists — no, the translator operates on plain text. For layout-critical documents, translate to .docx and reapply formatting in Word.

                        

                    

                    
                    

                        

                            
                        

                        

                            
No. Uploaded PDFs are extracted, translated, and the source file deleted. The translated output is kept on our CDN for 24 hours (7 days on a paid plan) at the share link.
