Frequently asked questions
How strong is the encryption?
AES-256, the strongest standard PDF encryption, supported by every current PDF viewer.
What if I forget the password?
The file can't be opened. We never see or store your password, so keep it safe.
Are the printing and copying restrictions enforced?
Mainstream viewers respect them, but some tools ignore them. The password itself is what keeps the content private.
Is there a file size limit for free users?
Free accounts and guests can process files up to 10 MB. Pro and Team raise the limit to 100 MB per file.
Do I need to create an account or install software?
There's nothing to install: the tool runs in your web browser. You can drop a file and process it right away without an account. To download the result, sign in or create a free account (3 free downloads a month), or go Pro for unlimited downloads.
Is it free?
Yes. With a free account you can download up to 3 files a month from any tool, or upgrade to Pro for unlimited use.
