How do you create a time lock/ expiration on an adobe acrobat pdf file? Is there a way to make the file become expired or locked after a certain number of days?

Hi Captivating_kidd8d0,

Thank you for reaching out.

In Acrobat, there is no built-in feature to either time lock or add expiration to an PDF. If you can share more information on what you are trying here, we may share the some information.

Please also refer to the information here: https://business.adobe.com/blog/basics/digital-rights-management. Check if you are looking for something like this.

Let us know if you have ay questions or need help.

Thanks,
