About PDFArk
PDFArk was founded on a simple principle: Everyday PDF tasks should not require uploading confidential contracts, medical paperwork, or financial spreadsheets to remote cloud servers.
Privacy by Architecture
Unlike traditional PDF sites that operate document conversion servers, PDFArk has no database, no file upload endpoint, and no file caching storage.
Local Browser Power
By leveraging modern web standards including WebAssembly, Web Workers, and the HTML5 Canvas API, your computer's native CPU handles all manipulation in real-time.
Our Open Architectural Promise
When you use PDFArk, you can inspect your browser's Network tab in DevTools at any point. You will observe that when you select, merge, split, or convert documents, zero document payload bytes are transmitted over the Internet.
The result is instant processing without server queue delays, maximum file confidentiality, and an online utility suite you can trust with your most critical personal and business files.
