PDF Translate is a browser-based AI translation service that converts uploaded PDF documents into over 60 languages while preserving the original layout, fonts, tables, and images.
What is PDF Translate?
PDF Translate (pdf-translation.com) is an online document translation tool that accepts PDF files (recommended under 50MB) and outputs fully translated single-language or dual-column bilingual PDFs. It runs entirely in the browser with no software installation required, and supports scanned pages, formulas, and tables. The service offers free access to Google Translate and Bing Translate engines, with premium options (OpenAI, DeepL Pro) available to subscribers.
Key Features
- Layout preservation — Translated PDFs retain the original fonts, images, tables, and formula positioning; regex rules can be applied to protect mathematical variables and character patterns.
- Multiple translation engines — Free users can choose between Google Translate and Bing Translate; subscribers unlock OpenAI and DeepL Pro for higher-quality output.
- Custom prompts and advanced options — Users can set a custom system prompt, define regex patterns for formula fonts (vfont) and character preservation (vchar), and enable or disable table translation.
- Real-time progress page — After clicking “Start translation”, the tool opens a live page with cancel/retry support and download access once processing completes.
- Document summaries and Q&A — Beyond full translation, the service can produce AI-generated summaries of lengthy reports and answer questions about the document content.
- Bilingual output — Translated files can be downloaded as single-language PDFs or side-by-side dual-column PDFs for easy comparison.
Who is it for?
- Researchers and academics — Translate technical papers, reports, and patents while keeping mathematical formulas, citations, and headings intact.
- Business professionals — Convert contracts, invoices, and annual reports into multiple languages for international teams or clients, with table layout preserved.
- Educators and students — Translate lesson decks, study materials, or multilingual assignments directly in the browser, supporting both scanned and digital PDFs.
What can you do with PDF Translate?
- Translate a full PDF quickly — Upload a file, pick source and target languages (100+ combinations), and download the translated PDF in seconds, with layout and formatting unchanged.
- Ask questions about a document — Use the built-in document Q&A feature to pose a question to the AI and receive an answer with context from the file, useful for quick comprehension without reading the entire translation.
- Generate a summary before translating — Highlight key points of lengthy reports using the free summary feature, then decide whether to proceed with a full translation.
How does PDF Translate work?
Upload a PDF by dragging and dropping it into the browser window or selecting it from your device. Choose the source language (or let the AI detect it) and the target language, then optionally configure advanced options (regex for fonts, character preservation, custom prompts). Click “Start translation” to create a task; the service opens a live progress page where you can monitor, cancel, or retry the job, and download the final translated PDF once complete.
