What Decrypt PDF is good for
Private, sensitive documents
Contracts, IDs, medical records and financial statements should not be uploaded to a stranger's server. With Decrypt PDF, they never leave your device.
Working offline or on the move
On a plane, on a train, or behind a strict firewall — Decrypt PDF keeps working without a connection once loaded.
Quick, repeatable tasks
No accounts, no installs, no daily limits. Open the page, get the job done, and close the tab.
Frequently asked questions
- Is Decrypt PDF free to use?
- Yes. Decrypt PDF is completely free, with no sign-up, watermarks, daily quotas, or file-size caps. You can process as many files as your device can handle.
- Are my files uploaded to a server?
- No. Decrypt PDF runs entirely in your browser using WebAssembly. Your documents never leave your device — there are no uploads, no servers, and nothing is stored or logged. That is what makes PDF-Atlas private by architecture.
- Does Decrypt PDF work offline?
- Yes. After the page has loaded once, the tool keeps working without an internet connection. You can also install PDF-Atlas as a desktop app or PWA for a fully offline experience.
- Is my data safe?
- Because all processing happens locally on your machine, your files are as safe as the device they sit on. Nothing is transmitted to PDF-Atlas or any third party.
