What is PDFTranslator.org?

PDFTranslator.org is a free online tool for translating PDF documents using AI. It’s designed to translate across 100+ languages while preserving the original formatting in the output file.

The tool supports both text-based PDFs and scanned/image-based PDFs via OCR, helping users translate documents that would otherwise require manual transcription.

Key Features

• 100+ language translation: Supports translation between widely used languages and less common/low-resource languages listed on the site.
• OCR PDF translation: Translates scanned documents by extracting text from images before translating.
• Long PDF handling: Designed to translate extensive documents (the site notes support for long PDFs containing hundreds of pages).
• Secure processing: Uses SSL and automatically permanently deletes uploaded files from its servers within 1 hour after translation.
• No sign-up required / 100% free: Runs without accounts, credit cards, or hidden fees (as stated on the page).
• Source language selection and translation to a target language: Users choose the source and target languages before starting translation.

FAQ

Alternatives

• Standalone PDF translators or desktop translation apps: These may also translate PDFs and sometimes preserve formatting, but workflows differ (upload vs. local processing) and privacy/deletion policies vary.
• General-purpose machine translation tools (web or API) that accept text extraction: If your workflow can extract text from PDFs, these tools can translate content, but they may not preserve the original PDF layout as consistently.
• OCR + translation workflow tools: For scanned PDFs, some solutions split the job into OCR first and then translation; this can offer more control but may require more steps to maintain formatting.
