A free set of PDF tools that run fully inside your browser. There's no upload step, because there's no server on the other end waiting for your document — everything happens on the device in your hands.
// the toolkit
19 tools and counting — new ones get added as they're needed, and old ones get retired if nobody uses them, so think of this as the current set, not a fixed number. Each one is a self-contained page: open it, drop a file in, and everything after that happens in your browser's own memory.
// Organize pages
Combine multiple PDFs into one, in any order.
Divide one file into several smaller ones.
Drag pages into the order you actually want.
Pull specific pages out into a new file.
Remove pages you don't need, in bulk or one by one.
Fix sideways or upside-down scans.
Arrange pages for print-and-fold booklets.
// Edit & sign
// Convert
// Protect & optimize
// why local processing matters
Most free PDF tools work by sending your file to a server, doing the work there, and sending a result back. That's not a flaw exactly — it's just how most web tools are built. But it means your bank statement, signed contract, or ID scan briefly exists on a machine you don't control, on a network you can't see.
Cloud storage and file-processing services are also a real target: industry breach reports consistently show cloud environments among the most frequently attacked infrastructure, and misconfigurations — not sophisticated hacking — cause the majority of exposures.
OfflinePDF was built to remove that step entirely. The processing code (open web standards like PDF.js and pdf-lib) is loaded into your browser once, and every merge, split, or edit after that runs locally — the same way a calculator app doesn't send your sums to a server. You can confirm this yourself: open your browser's network panel while using any tool here, and choose a file. You won't see a single upload request.

// common questions
No. Every tool processes your file using code that runs inside your own browser tab. You can verify this by opening your browser's developer tools and watching the network requests while you use any tool — none will contain your file.
No account, email, or sign-in is required for any tool on the site.
Once a tool page has loaded, yes — the processing itself needs no network connection at all.
Yes, with no usage limits, watermarks, or paywalled features.
// how it works
For the full technical walkthrough, see our how it works page and our guides for step-by-step help with each tool.
The page loads a small processing engine directly in your browser.
It's read into memory on your device — never attached to a request.
The finished file is generated locally and downloaded straight to you.
