PdfTranslator
Translate papers & books without losing 1:1 layout
Professional AI Translator Keeping Original Layout Layout. Deeply optimized for various mainstream document types including academic papers, business contracts, patent documents, and presentations. One-tap mutual translation, keeping the original formatting intact.
As someone who reads dozens of ArXiv papers, technical specs, and digital books daily, reading dense multi-column pages in my second language was draining my brain.
The Problem:
Existing translation tools drove me crazy. Google and DeepL break multi-column layouts, overlapping text and making pages unreadable. Dropping full PDFs into ChatGPT/Claude burns tokens insanely fast, merges columns randomly, and turns math formulas into broken gibberish.
How I Solved It:
I built PdfTranslator for iOS—a lightweight app designed to translate PDFs without ruining their structure.
1. 1:1 Layout Preservation: ArXiv papers, scanned books, and manuals keep their original visual structure. Multi-column text, tables, and inline math formulas stay exactly where they belong.
2. Smart Text Auto-Fitting: Dynamically adjusts font sizes and line heights so translated text fits the page gracefully without overflowing or overlapping neighboring elements.
3. Unlimited On-Device Mode: Uses local OCR and native iOS translation for 100% offline privacy, zero server costs, and zero page limits.
4. Smart LLM Mode: Passes structured text to AI for high-precision jargon translation without wasting tokens on layout overhead.
I built this tool to solve my own daily headache, and it has completely changed my reading workflow.
