Our mission

PDF8 was built on a simple premise: processing your PDFs should not require surrendering your privacy. Most online PDF tools ask you to upload files to their servers — meaning your contracts, invoices, and personal documents pass through systems you do not control. We believe that is unnecessary.

Every tool on PDF8 runs completely in your browser using WebAssembly. Your files are never uploaded, never stored, and never touched by any server. This architecture makes true privacy the default, not an upgrade.

How it works

Under the hood, PDF8 uses pdf-lib, a powerful PDF manipulation library compiled to WebAssembly. When you select a file and click a button, the PDF is read directly from your device, processed by JavaScript running in your browser tab, and a new PDF is generated — all without any network requests to external servers.

This approach means there are no file size limits beyond what your browser can handle, no queues, no account registration, and no audit trails on third-party infrastructure. The tool works offline after the initial page load.

Why we built it

Cloud PDF services typically monetize through subscriptions, file size caps, or data collection. We wanted to offer a set of essential PDF utilities that respect the user's privacy as a fundamental design constraint, not as a marketing afterthought. PDF8 is free, open in how it works, and does not track you or your documents.
