Hi angela,

Open the File Properties (File > Properties) and select the Security tab. It should have Password security selected. Change this to No Security.

Thanks,
Lori

I receive .pdf files with password to open from our tax preparer. How do I save the file without password or change to different password after I open it with password? I went to Security settings but can’t find where to delete the password. I don’t want to print it out then scan it and save with new password. Thanks.

Hi M.L.Jaiswal,

Yes, you’ll need Acrobat and not just the free Reader to set a security password on a PDF file.

Thanks,
Lori

Hi eric,

The ability to apply a password is only available in Acrobat and just the free Reader. You can use Reader to open a PDF that has a password but you’ll need to know the password to open the file.

Thanks,
Lori

Hi Teri Johnson,

In the print dialog, with the PDF printer selected click on the Properties button. What setting is selected under the Default Settings dropdown? Make sure it is a setting that embeds fonts—like Standard.

Thanks,
Lori

Lori,
My tax and accounting software (CCH-ATX tax software, Quickbooks and Peachtree Accounting) we can run a report and click the PDF button within the software and it then creates a PDF. In my tax software I actually click print and then chosse the pdf printer…... It is those that now get garbled when applying a password.  It never did it before Acrobat 9.  I have been passwording for a couple years now.  However, when I scan a document directly using my Fujitsu Scansnap and Acrobat 9 it seems to work.  The taxes are two many pages to print then scan…..would take too much time….....The other issue I notice is when I open a document now and add a comment it says it is read only and I have to do a save as and rename it to have the comment saved.  Never had to do that before either.  Seems Acrobat 9 is slowing me down this tax season with these issues.

Hi Teri,

Can you be more specific on how your PDF document is created? Are you using Acrobat or a different tool?

Thanks,

Same thing is happening to me - and it did not happen prior to using version 9….I notice if I actually scan a document and then set a password it does not garble the fonts..but if I save a document as pdf from within a program and then set a password it garbles…I need a fix fast…

Hi Laurie,

I’m not sure what you mean by garbled. Do you mean that the fonts don’t display properly? If so, try removing the password and re-applying using a different compatibility setting.

Thanks,
Lori

I did this and now the document I password protected is garbled. I do not see any information on the site about this.
