What is AI PDF Translator?
BoostPDF Translator is a powerful dual-view translation tool that uses artificial intelligence to convert PDF documents from one language to another while keeping your original document 100% pristine. Unlike traditional "overwrite" tools that break formatting, our side-by-side interface lets you verify every translation against the source.
Whether you're a law student analyzing foreign case files, an engineer reviewing international specs, or a researcher accessing publications in any language—our AI handles scanned PDFs, technical terminology, and complex layouts with automatic OCR detection.
Dual-View Translation: Load your PDF, let our AI auto-detect and OCR if needed, select your target language from 37 options, and access Dual-View Mode with your original document on the left and translated text on the right. Pagination syncs automatically.
How to Translate PDFs with Verified Accuracy
Translating your PDF takes just five simple steps:
- Load Your Document: Drag and drop your PDF (contracts, lecture slides, or whitepapers). Our system accepts files up to 10MB for free users and 100MB for premium users.
- Smart-Detect & OCR: If your PDF is a flat scan or image-based, our AI automatically engages OCR to extract the text layer without you needing to configure settings.
- Select Target Language: Choose from 37 high-accuracy languages. Our engine optimizes for technical and academic nuance rather than generic conversational phrasing.
- Access Dual-View Mode: The interface opens a split-screen: your original document on the left, the translated text on the right. Pagination is synced automatically.
- Download Your Translation: Copy the translated text to your clipboard or download it as a separate document for your records.
Supported Languages
Our AI translation engine supports 37 languages: English, Spanish, French, German, Italian, Portuguese, Dutch, Russian, Chinese, Japanese, Korean, Arabic, Hindi, Thai, Vietnamese, Turkish, Polish, Swedish, Danish, Norwegian, Finnish, Greek, Hebrew, Czech, Romanian, Hungarian, Indonesian, Malay, Filipino, Ukrainian, Bulgarian, Croatian, Slovak, Slovenian, Estonian, Latvian, and Lithuanian.
Technical & Academic Focus: Our engine optimizes for technical and academic nuance rather than generic conversational phrasing, making it ideal for contracts, research papers, and specifications.
Why Professionals and Students Prefer Dual-View Over "Overwrite" Tools
Our side-by-side translation interface offers significant advantages over traditional tools that try to replace text in place:
- Zero Layout Destruction (The "Format Anxiety" Solution) Standard tools try to force translated text into the original text boxes. When the text expands (e.g., English to Spanish), this breaks tables, ruins charts, and pushes content onto wrong pages. Because we render translations side-by-side, your original charts, legal formatting, and citations remain 100% pristine.
- The "Trust but Verify" Workflow For law students analyzing case files or engineers reviewing specs, "mostly accurate" isn't enough. Our Side-by-Side view allows you to instantly cross-reference specific terms against the source language. You don't have to flip between windows to check if the AI hallucinated a number or clause.
- Automatic Handling of "Unreadable" Files Most converters fail when you upload a scanned invoice or an old library book scan. Our tool detects the lack of a text layer and instantly routes the file through our OCR (Optical Character Recognition) engine before translation begins. You get a clean, searchable text output from a flat image.
- Non-Destructive Integrity We never alter your original file. For compliance officers and researchers, maintaining the file hash and integrity of the source document is critical. Our tool acts as a viewing layer, not an editing layer, ensuring your source material is never corrupted.
Pro Tip: Once you have your verified translation, you can use our PDF Chat Tool to ask questions directly to the document ("What is the termination clause date?") to speed up your review.

Frequently Asked Questions
Will this tool work on scanned PDFs that I can't highlight text in?
Yes. The system detects "flat" PDFs immediately. It runs an auto-OCR process to recognize the text characters within the image before translating them, so you don't need to convert the file first.
Does the translation keep the same page numbers as the original?
Yes. Our pagination sync ensures that text on Page 14 of your source document appears under "Page 14" in the translated view. This is essential for accurate citations in academic papers and referencing specific clauses in contracts.
Can I edit the translated text if I spot an error?
No, to ensure the integrity of the document, the output is read-only. However, you can copy specific sections of the translated text out to your clipboard for use in Word or Google Docs.
