PDF Translate Introduction

PDF Translate is a browser‑based AI translation service that converts entire PDF documents while preserving layout, fonts, tables, and images. Users upload a single file (recommended < 50 MB), select source and target languages from over 100 options, and choose a translation engine such as Google Translate, Bing, DeepL Pro, or OpenAI (subscriber only). The platform offers advanced controls for formula and character preservation via regex, optional table translation, and custom prompts, making it suitable for technical manuals, research papers, invoices, and literary works. Results are delivered as mono‑column or side‑by‑side bilingual PDFs, and the same interface supports scanned PDFs, document summaries, and Q&A queries. TLS encryption, GDPR‑aligned policies, and one‑click purge ensure document security. An API and cross‑device compatibility allow seamless integration into academic or business workflows.

PDF Translate processes a PDF entirely within the browser: the user uploads a file (recommended < 50 MB), selects source and target languages, and chooses a translation engine such as Google Translate, Bing, OpenAI or DeepL. The service extracts text, tables, images and optional formula fonts, then sends the content to the selected AI model. Returned translations are re‑inserted while preserving original layout, fonts, and spacing; regular expressions can protect specific characters or formulas. After processing, the platform streams a preview and allows download of a single‑language or side‑by‑side bilingual PDF, supporting over 100 language pairs.

PDF Translate provides a browser‑based AI translator that converts entire PDFs while preserving layout, fonts, tables, and images. Users upload a single file (recommended under 50 MB), select source and target languages from more than 100 combinations, and choose from free engines (Google, Bing) or premium models (OpenAI, DeepL) via a subscription. The service supports scanned documents, formula and character‑preservation regex, and offers mono‑ or dual‑column outputs for review. Real‑time progress, secure TLS encryption, and an optional API enable seamless integration into academic, business, or research workflows without installing software.
