AskPDF is a free, 100% private in-browser document suite & AI copilot. It allows you to merge, split, compress, convert, password protect, and chat with PDFs directly inside your web browser with zero server uploads.

Are my confidential files uploaded or saved on a server?

No. Unlike legacy PDF sites that upload files to remote servers, AskPDF executes 100% of processing on your device using WebAssembly, HTML5 Canvas, and client-side JavaScript. Your files never leave your computer or phone, ensuring full compliance with GDPR and HIPAA guidelines.

How does AI Chat with PDF work?

AskPDF allows you to connect free AI models (Google AI Studio, Groq, OpenRouter) or local LLMs (Ollama) to read, summarize, and cross-examine multi-page documents directly in your browser with zero data retention.

Can I password protect a PDF with AES-256 encryption?

Yes. AskPDF provides standard 256-bit AES encryption compliant with Adobe Acrobat, ISO 32000-2, and modern PDF viewers.

Can I convert scanned PDF tables to Microsoft Excel?

Yes. AskPDF features a 2D spatial layout table extractor that detects rows and columns in invoices, bank statements, and spreadsheets, exporting clean .xlsx files without artificial empty spacer columns.

Is AskPDF really 100% free with no limits?

Yes! AskPDF is completely free with no daily quotas, no watermarks, and no mandatory signup.
