Sending sensitive documents by email
Email is rarely encrypted in transit end-to-end. Password protection means the file is unreadable even if the email is intercepted or forwarded by mistake.

How it works
Pick a password, encrypt, send. Recipients need the password to open the file.
1
Drop your PDF
Add a single PDF up to 100 MB. The original file on your device stays unchanged.
2
Choose a password
Type the password twice so you don't lock yourself out by typo. Use something a recipient can remember if you'll be sharing the password too.
3
Download the protected PDF
The protected copy comes back as a separate file. Sharing it requires sharing the password by a different channel.
What people use it for
Posting files to shared drives
On a shared drive that more people can access than should, a password limits who actually opens the file.
Sharing through messaging apps
PDFs forwarded through Slack, WhatsApp, or Telegram pass through company and platform servers. A password keeps the contents private if the file ends up somewhere you didn't intend.
Sending IDs or signed contracts
Anything with personal identification numbers or signatures benefits from a layer the recipient has to actively unlock.
