Benefits
Private by design
Your file stays on your device while Secure Sharing works. Secure Sharing never sends it to a server, so confidential work stays confidential.
Instant results
Secure Sharing finishes most jobs in under a second because the work happens on your own hardware.
No signup, no limits
Use Secure Sharing as many times as you want. Secure Sharing asks for no account, adds no watermark and keeps no paid tier gating the output.
Works offline
Once the page has loaded, Secure Sharing keeps working without a connection, which helps on flights and locked-down networks.
Who it is for
For legal and finance teams
Legal and finance teams use Secure Sharing to handle sensitive documents without installing software: prepare PDF for secure sharing on a shared or locked-down machine.
For HR and admin teams
Secure Sharing helps HR and admin teams process paperwork quickly, since your file never leaves the laptop it was created on.
For freelancers
Secure Sharing helps freelancers send client deliverables quickly, since your file never leaves the laptop it was created on.
How it works
Secure Sharing loads your file into memory, applies the change you requested to the underlying data rather than to a screenshot of it, and writes a fresh copy for download. Your original stays untouched on disk, and every step of Secure Sharing happens inside your browser sandbox.
Frequently asked questions
Is Secure Sharing free to use?
Yes. Secure Sharing is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.
Does Secure Sharing upload your file to a server?
No. Secure Sharing processes your file inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.
Is there a file size limit?
The practical ceiling is your device's available memory rather than a server quota. Files up to roughly 100 MB work comfortably on a typical laptop in Secure Sharing.
Do I need to install anything to use Secure Sharing?
No installation is needed. Secure Sharing runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Can I use Secure Sharing on a phone or tablet?
Yes. The Secure Sharing interface adapts to small screens and supports touch input, though very large jobs are faster on a desktop browser.
What happens to your file when I close the tab?
It is discarded. Secure Sharing keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
