What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Very Quick, saves me a lot of time. I regularly get pdf's that need to be completed and sent back. Now I can upload, fill out and return in a fraction of the time. Since the data is typed, I never get a question about what I wrote.

I'd rather pay per document. I don't need the subscription and will likely cancel after this transaction. Consider offering a cheap per-page service in the future.

So far it has been user friendly. I am sure it can do a lot more than what I am doing right now but I am learning more as I go a long. I think a webinar would be very helpful

As a new small business operator, this software has helped me with so many tasks without having to leave work. The only draw back is that many times, recipients can't open sent pdf files and another route has to be taken.

PDFfiller is great if you need to edit/change PDFs This software allows us to fill out and share PDFs, vastly cutting down on our printing/scanning song and dance. No real negatives other than I wish it were free.

I grew tired of waiting for my colleague to get around to fixing our PDFs. This program has made it quick and easy for me to accomplish what we really needed to help our clients! I am very pleased with how intuitive it has been.

So far this program is a game changer. I wish it was cheaper (a discount for teachers on a year subscription would be wonderful!!) but I like what I am seeing so far;)

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.
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.
