AI PDF Translator — Translate PDF Content Instantly

The AI translator supports 50+ languages grouped by region: Popular (English, Spanish, French, German, Chinese, Japanese, Korean, Arabic, Hindi), European (Italian, Dutch, Polish, Swedish, and more), Asian (Thai, Vietnamese, Indonesian, Bengali, Tamil), and Middle Eastern/African (Turkish, Hebrew, Persian, Swahili). Search for any language by name.

Standard produces natural, balanced translations. Formal uses a professional register suited for legal, business, and academic documents with precise terminology. Casual simplifies complex sentences into conversational, everyday language.

When enabled, the translation shows each original paragraph followed by its translation, making it easy to compare and verify the translation side by side. This is especially useful for legal review, academic study, and quality assurance.

Yes. The AI automatically detects the language of your PDF and shows it in the result (e.g., 'German → English'). You don't need to specify the source language manually.

Claude AI provides high-quality, context-aware translations that understand meaning, not just word-for-word substitution. It handles idioms, technical terminology, and domain-specific language well. For critical legal or medical documents, we recommend human review after AI translation.

The translator preserves document structure: paragraph breaks, numbered lists, headings, and flow. The output is text (TXT/MD), not a re-formatted PDF. For complex layouts with tables, columns, or embedded images, the text structure is maintained but visual formatting may differ.

WhiskFile supports PDFs up to 500 pages. The AI extracts and translates all text comprehensively. Very long documents are processed efficiently — you'll see the word count and detected language when translation is complete.

Scanned PDFs (images of text) need OCR processing first. Use WhiskFile's OCR PDF tool to add a text layer, then upload the OCR'd PDF for translation. The AI can then read and translate the extracted text.

Currently, you translate to one target language per session. To translate to multiple languages, run the tool once per language. Each translation takes just seconds.

Context-aware. Claude AI understands meaning, idioms, domain terminology, and sentence structure. It produces natural, fluent translations — not literal word-for-word output. This is especially important for legal, technical, and academic documents.

Yes. The AI auto-detects the source language, so you don't need to specify it. It works with all major world languages and many less common ones. The detected source language is shown in the results.

Yes. Your document text is processed in memory and never stored permanently. It is not used to train AI models. The file is deleted from WhiskFile servers within 1 hour of upload.

WhiskFile provides tone control (formal/casual), bilingual side-by-side output, and context-aware AI translation that handles domain-specific terminology. Google Translate processes PDFs as flat text without these features. WhiskFile also preserves document structure and headings.
