How do I translate a PDF with PDF Translate?

To translate a PDF, users drag and drop the file onto the upload area or click Select PDF, then choose the source and target languages from the dropdown menus. After selecting a translation model (Google Translate, Bing, OpenAI, or DeepL for subscribers), they press Start translation and wait for the real‑time progress page to finish. Finally, the translated PDF can be downloaded in single‑language or bilingual side‑by‑side format.

Is PDF Translate free to use?

PDF Translate offers a free tier that allows basic translations using Google or Bing engines. Users can translate entire PDFs, preview quality, and download results without any payment. Premium features—such as OpenAI, DeepL, custom prompts, and advanced regex options—require a monthly or yearly subscription.

How long does a PDF translation take?

Translation speed depends on file size and chosen engine. For files under 50 MB, most translations complete within seconds to a few minutes. Larger or scanned PDFs may require additional processing time, but the platform streams results so users can view partial output while the rest of the document is being translated.

Can I switch between translation engines?

Yes. After uploading a PDF, the Translation model / service dropdown lets users choose Google Translate, Bing Translate, OpenAI (subscriber only), or DeepL Pro (subscriber only). Basic users are limited to Google or Bing, while paid subscribers can enable the premium engines for potentially higher quality or domain‑specific translations.

Will the PDF layout remain intact after translation?

PDF Translate is designed to preserve the original layout, fonts, tables, images, and even mathematical formulas. Advanced options such as Formula font regex and Character‑preservation regex let users protect specific elements from being altered, ensuring that the translated PDF retains the same visual structure as the source document.

Does PDF Translate support scanned PDFs?

Scanned PDFs are accepted and processed using OCR technology before translation. The service extracts text from images, applies the selected AI model, and then recreates the PDF with the original layout while embedding the translated text. This allows users to translate printed documents, textbooks, or legacy reports without needing separate OCR software.

How many languages does PDF Translate support?

The platform supports more than 100 language combinations, covering major languages such as English, Chinese (Simplified and Traditional), Spanish, Hindi, Arabic, Portuguese (Brazil and Portugal), Russian, Japanese, Korean, German, French, and many others. Language coverage is updated weekly, and new pairs can be requested through the support channel.

Can I translate very large or book‑length PDFs?

PDF Translate can handle large documents, including academic papers, multi‑chapter books, and extensive reports. While the recommended file size for optimal performance is under 50 MB, larger PDFs are still accepted; they may take longer to upload and process, but the service will preserve headings, footnotes, and cross‑references throughout the translation.

Is my data secure during the translation process?

All uploads are protected with TLS encryption from the browser to the server. PDF Translate follows ISO/IEC and GDPR‑aligned retention policies, and users can delete files instantly with a single‑click purge. No advertising or third‑party tracking is embedded, ensuring that confidential or proprietary information remains private.
