NextPDF Professional Key Features:
Security level:
you can set the security level for the PDF such as: only print in low quality, view only or no copying allowed.

1. "Security" option

Owner Password
The password that is required to change security settings in Adobe Acrobat. If the reader of the document knows this password he can change any security settings, including all passwords.

User Password
The password that is required to read the document. User password does not give the reader the capability to change any security setting.

Allow printing
If not selected, readers will not be able to print the document in optimal quality. If "Allow low-quality printing" is not selected, readers will not be able to print the document at all.

Allow copy to clipboard
If this checkbox is not ticked, readers will not be able to copy document content by copying text or graphics to the clipboard and then pasting the content into another application. If you allow copying to clipboard you also automatically enable the "Allow screen readers" options and other accessibility tools can access to the content of your document.

Allow screen readers
If this checkbox is not ticked, readers will not be able to read the document on screen or use other accessibility tools to interact with your document.

Allow low-quality printing
If you clear "Allow printing" but select this checkbox then users will be able to print your document, but not in high-quality.

2. Encryption

Applies encrpytion to your PDF output file to ensure only authorized users can view its content. Two different encryption modes are available: 40 bit encryption is back-compatible with Adobe Acrobat versions before 5.0. It is less secure but faster but does not provide as many features as 128 bit encryption. 128 bit encryption is more secure but requires more processing time. It offers extra security features, such as the capability to allow low-quality printing, but only works with Acrobat 5 and above.

3. Watermarking

Check on the "Watermaking" checkbox and then specify a PDF file as the watermark stamp. If the page size of the watermark PDF file is different from the output, the watermark file will be automatically scaled to fit with the output size.
