I really enjoy PDF filler. It is way more user friendly than Adobe Pro and it is so convenient for it to be a website that I can access from anywhere. Who ever created this is a genius!!!!!!!!!!!!

The reason it is a four instead of a five...
The reason it is a four instead of a five is I feel like there is a strong learning curve... at least for me.
So I am still learning.
Check back with me in a month and let's see if we can delete this 4 rating and move it up to a 5!!

Just like last year!
I must file my church's taxes for our employees every year. I found this site last year. I love it! I prints the information I need. I can make copies and send it. I could send directly to IRS but chose not to do that route!!

Excellent customer service!
I used the pdfFiller when I had no access to a printer- it was efficient and easy to use. However this was a one off and thought I had cancelled my subscription. When I saw I was being charged I was concerned as I have no need for the service on a subscription, however I contacted pdfFiller customer services explaining my situation and I received a very reassuring reply from Max and the pending transaction was cancelled immediately. If I ever need the service again I wouldn’t hesitate to use pdfFiller or recommend them. Outstanding customer service.

Appreciate to keep the pricing say…
Appreciate to keep the pricing say within $10 and max of say 10 docs instead of $20 per month. No contract please

Honesty and integrity are not something…
Honesty and integrity are not something I align with online trial subscription. Most will hope you forget so they can charge you anyway. But PDFfilIer holds to a higher standard. I am NOT an employee forced to write a review. This for real just happened like 10 minutes ago.
I signed up for a trial to complete a job for my employer. Forgot to cancel before the trial ended. I don't make much, so $96 was a hit I wasn't expecting or able to pay. Support had already approved and completed the refund and cancelation of my subscription before I had even finished explaining my situation to the rep in chat (Aiden). The email came from "Sarah from PDFfiller" explaining that it was taken care of while I was still chatting with the rep.
I was expecting a battle. Now I expect to either sign up with PDFfiller when I have a more consistent need or get my boss to pay for the service. The platform was quick and easy to navigate. Based solely on this experience, I would recommend this platform if you are in need of creating these types of documents.
The only thing I would change is that I couldn't find my payment options in my account info to see what card was used. Nor could I find an avenue to change my payment options.

PdfFiller is one of the better pdf apps that I've used in some time. I was especially impressed with how it handles pictures/logos that one might use in a document.

Is there a way to lock files on a Mac?
Folders can't be directly encrypted in macOS, but you can put them in password-protected containers. This has the effect of protecting your folders and the files they contain with a password. You can password-protect folders on macOS using the built-in Disk Utility application or a third-party tool called Encrypt.
How do I lock a PDF on a Mac?
In the Preview app on your Mac, open the PDF that you want to password-protect.
Choose File > Export, then select Encrypt. You can also enter a new name for the PDF if you want to create a pass worded copy and keep the original PDF unencrypted.
Type a password, then retype it to verify the password.
Click Save.
