Everything runs in your browser. Your PDF is never uploaded to any server.
Client Side PDF's AI Assistant is a comprehensive, browser-based PDF automation toolkit that processes your documents entirely on your device. Unlike traditional online PDF tools that upload your files to remote servers, our technology uses WebGPU and WebAssembly to run AI models directly in your browser, enabling intelligent document processing without compromising privacy.
Ask questions about any document and get instant answers. The AI reads and understands your PDF content, providing accurate summaries, extracting key information, and answering specific queries about the text.
Automatically detect and extract tables from PDF documents into downloadable Excel spreadsheets (.xlsx). Perfect for financial reports, invoices, data sheets, and any document containing tabular data.
Transform PDF documents into fully editable Microsoft Word files (.docx). Our AI-assisted conversion preserves formatting, headings, and document structure for seamless editing in Word or Google Docs.
Convert PDF pages to high-quality PNG or JPG images. Ideal for presentations, social media sharing, or when you need individual page images from multi-page documents.
Draw your signature and add it to PDF documents. The AI helps position your signature appropriately on the document, making it easy to sign contracts, forms, and agreements.
All processing happens locally in your web browser using WebGPU technology. Your documents never leave your device — the most secure way to automate PDF tasks online.
The intelligent document processing (IDP) market is experiencing rapid growth. According to industry research, the global IDP market was valued at approximately $2.3 billion in 2024 and is projected to reach $66 billion by 2032, growing at a compound annual growth rate (CAGR) of over 30%. This growth is driven by organizations seeking to automate document-intensive workflows and reduce manual data entry errors.
Key statistics highlight the impact of document automation:
Traditional PDF tools require uploading your documents to cloud servers, creating privacy risks for sensitive information like contracts, financial documents, medical records, or personal data. Client Side PDF eliminates this risk entirely by processing everything locally using large language models (LLMs) that run in your browser:
Our PDF automation tools use optical character recognition (OCR) combined with AI-powered natural language processing (NLP) to understand document content. The underlying technology leverages open-source models like Llama running via WebLLM, which enables browser-based inference without server communication.
This approach combines advances in retrieval-augmented generation (RAG) with client-side execution, allowing the AI to answer questions about your specific document while keeping all data local. Recent research on efficient document AI (arXiv:2408.02545) demonstrates how specialized models can be optimized for edge deployment — the approach we use to bring powerful PDF automation directly to your browser.
Our AI-powered features require WebGPU support, available in Google Chrome 113+, Microsoft Edge 113+, and other Chromium-based browsers. Basic PDF viewing and conversion features work in all modern browsers including Firefox and Safari.
Is my PDF really processed locally?
Yes. All document processing happens in your browser using JavaScript and WebAssembly. Your files are never uploaded to any server. You can verify this by monitoring network requests in your browser's developer tools.
How does the AI work without internet?
The AI model is downloaded once (approximately 700MB-2.3GB depending on the model selected) and cached in your browser. After this initial download, the AI runs entirely offline using WebGPU acceleration.
What types of PDFs work best?
Text-based PDFs work best for AI analysis and conversion. Scanned documents require OCR processing first, which may affect accuracy. Complex layouts with multiple columns or extensive graphics may require manual review after conversion.
