Customer support was top notch. They resolved my print issues with my form. The reason I did not give it 5 stars and would not recommend is that I Googled for a form to fill out for a US Passport. I didn't expect to find one i could fill in on line. What was not apparent was that ONLY AFTER SPENDING 30 MINUTES FILLING OUT THE FORM did I find out I had to pay $20 to print, save, fax, email or share the form. Customer service was great, but did not want to sign up for a monthly pdf service or pay $20 for 1 form.

For pdfFiller’s FAQs

Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.
Lock a closed document: Select it, choose File > Get Info, then select Locked. Lock an open document: Hold the pointer to the right of the document title, click the arrow, then select Locked.
Locking a file doesn't prevent throwing it into the Trash, but you're prompted to proceed when you do so, since you obviously locked it with a purpose. The Get Info window's Locked option prevents changes on a single Mac, and modifies the item's Finder icon.
You can easily prevent changes being made on any files or folders in Mac OS X by locking the file or folder in question. This locking capability will also prevent the file or directory from being deleted, since the Trash will not empty while a file is in a locked state.
A computer file that can be used by only a single program or process at one time is considered a locked file. All operating systems use locked files. In most cases, the purpose of locking a file is to make sure it can't be edited, moved, or deleted while it's being used, either by you or some computer process.
Select the file or folder you want to encrypt. Right-click the file or folder and click Properties. On the General tab, click the Advanced button. Check “Encrypt contents to secure data" option. Click Apply and then OK.
Open the document that you want to password protect. Select File > Info. Select Protect Document > Encrypt with Password. Note: In Excel, select Protect Workbook. In PowerPoint, select Protect Presentation. Enter a password, and select OK. Re-enter the password, and select OK.
In Windows Explorer, navigate to the folder you want to password-protect. Right-click on the folder. Select Properties from the menu. On the dialog that appears, click the General tab. Click the Advanced button, then select Encrypt content to secure data. Double-click the folder to ensure you can access it.
