How PDFArk Protects Your Confidential Data
Traditional PDF websites upload your sensitive contracts, financial records, and private documents to third-party cloud servers. PDFArk is engineered completely differently.

All document rendering, page manipulation, text extraction, and image conversions run directly on your computer's CPU and memory via WebAssembly and JavaScript.
Zero Server Storage
PDFArk has no backend database, no file storage buckets, and no document telemetry. When you close the browser tab, your document buffers vanish from memory.

Frequently Asked Questions
Common questions about PDFArk and client-side processing.
Is PDFArk really 100% free with no hidden charges?
Yes. PDFArk requires no subscription, no credit card, and no user registration. Because all processing runs on your own device rather than expensive cloud servers, we can offer our full utility suite without billing users.
Are my confidential documents uploaded to any remote server?
Never. PDFArk has no file upload backend or remote database. The PDF processing code is loaded into your browser as static JavaScript, reads your files locally, and outputs the result directly to your computer.
Can I use PDFArk offline?
Once a tool page has finished loading in your browser, the document processing engines can run without network access because no server requests are required to process your files.
What is the maximum file size supported?
Most tools comfortably handle files up to 100 MB or batches of up to 30 documents. Because processing utilizes your browser memory, the practical limit depends on your device hardware.
