Privacy-Safe PDF Tools
How DocMint's Browser-Based Processing Works
DocMint uses WebAssembly — a technology that runs compiled code directly in your browser. When you process a PDF:
You select a file
The file is loaded into your browser's memory — it never leaves your device.
Processing happens locally
Our WebAssembly engine processes the PDF entirely within your browser tab.
You download the result
The processed file is generated in your browser and downloaded directly to your device.
AI Features — Also Private
DocMint's AI tools (summarize, ask, translate, classify) use Gemini AI with strict data handling. Your document content is processed for the AI request only and never stored or used for training.
Frequently Asked Questions

DocMint uses WebAssembly to run PDF processing algorithms directly in your browser. When you convert a PDF, the conversion happens locally on your device — no file is ever sent to a server.
Is a no-upload PDF converter slower?
No. Browser-based processing is often faster because there's no upload/download time. Processing happens instantly on your device.
What PDF conversions can I do without uploading?
DocMint supports 40+ PDF operations without uploads: PDF to Word, PDF to Excel, PDF to Image, Image to PDF, HTML to PDF, and many more — all processed in your browser.
Does DocMint work offline?
Once the DocMint page is loaded, most tools work without an internet connection since processing is local. AI features require internet for the AI model.
