For professionals
PDF tools that keep client files confidential
Built for lawyers, accountants, and anyone who can't upload sensitive documents to a stranger's server. Every tool runs in your browser — your files never leave your device.
The problem
Most “free online PDF tools” upload your file to their servers, process it there, and send it back. For privileged, regulated, or NDA-bound documents, that round trip is a risk you can't take — and often one you can't even disclose.
How PDF Bunker is different
Everything runs locally in your browser. There's nothing to upload, nothing for us to see, store, retain, or leak. The document stays on the device it started on — full stop.
Built for confidential work
Law firms
Privileged and confidential client documents stay on your machine — no third-party server ever receives the file.
Accountants & bookkeepers
Tax returns, statements, and client financials are processed locally — sensitive numbers never get uploaded.
Healthcare & clinics
Patient records and forms are edited in your browser, so protected information isn't sent to an outside service.
Finance & consulting
Deal docs, contracts, and reports under NDA never touch a cloud you don't control.
The tools professionals reach for
All private, all in your browser.
Frequently asked questions
Do my files get uploaded?
No — never. Every operation runs in your browser using JavaScript. Your documents are not transmitted to us or to any third party, and we have no copy to store or breach.
Can I use this for confidential or privileged client documents?
Because files never leave your device and we never receive or store them, there is no third-party handling of the document to account for. That removes the most common risk of online PDF tools — your file being uploaded to someone else's servers.
Is it compliant with regulations like HIPAA or GDPR?
PDF Bunker doesn't transmit, receive, or store your files, so there's no third-party processing of your data to disclose in the first place. Whether your overall workflow meets a specific regulation depends on more than one tool — but "nothing is uploaded" eliminates the biggest exposure. Consult your own compliance requirements for the full picture.
Does it work offline?
Yes. Once the page has loaded, the tools keep working with your internet disconnected — useful on locked-down firm networks or air-gapped machines.
Do partners and staff each need an account?
No account is required to use the tools. Anonymous use allows up to 5 operations per day; a free account gives unlimited basic operations for everyone on your team.
Keep your clients' files on your device.
