How can I share a PDF securely?

Encrypt the PDF before sending it and share the password link separately from the file link. Stormkey performs the encryption locally in the browser.

Is putting the password in the same email safe?

No. If the PDF link and password land in the same inbox, the protection is much weaker. Use a second channel for the password.

Does this work for multiple PDFs?

You can protect files up to your plan limit. For multiple PDFs, you can also combine them into a ZIP first.

Secure PDF sharing

Encrypt confidential PDFs before sending them by email.

Contracts, invoices, HR documents, and customer files should not travel as plain attachments. Stormkey protects PDFs in your browser, then lets you send a protected file link.

Protect a PDF now

No plain-text storage

Encryption happens locally. The original file and password are not sent to Stormkey in plain text.

Simple delivery

After protection, the file can be sent by email, messenger, or download link.

Better separation

PDF and password stay separated, which is where many sharing workflows fail.

PDF passwords are not always enough

Built-in PDF password features depend on tools and settings, and recipients often cannot tell what kind of protection was used.

Stormkey makes protection a deliberate step: choose a file, encrypt it, send the protected file link, and share the password link separately.

The core security gain is not just encryption. It is separating the file from the password.

Can I send the protected PDF by email?

Yes. Send the protected file link by email, but do not place the password in the same message.

Is this intended for business documents?

Yes, especially for recurring confidential file exchanges between teams, customers, and partners.
