I am not very computer savvy and I am learning as I go with this new MacPro, but so far it has been a very helpful tool and plenty of help explaining how.

I am just learning to use but find it relatively easy to load, fill, save and print. I even figured out how to rotate forms outside the system and make it work. Cool.

OVERALL FAIR-GOOD EXPERIENCE. MAJOR FLAW: FORMATTING IS NOT CONSISTENT FROM TABLET TO LAPTOP.SIGNIFICANT EDITING REQUIRED. VERY TIME CONSUMING AND NON-PRODUCTIVE.
2016-09-06
Slick tool. Nice editing capabilities. Some of the menus are confusing - for example: finding where to update an existing link to fill document is challenging.

I love pdffiller
I love pdffiller! I need to print out some address labels for my church and this is perfect for that! The only other option would be to purchase Microsoft Word 365, which is $100/year. i was going to cancel my pdffiller subscription because I can't afford the normal cost of $80/year, but then I got offered a coupon to stay for only $20 so I took it! I can afford that. Thank you so much! You are a lifesaver! I don't know how else I would have been able to print out my address labels.

Great Tool!
My experience has been great thus far. The use is seamless whether on my tablet, laptop, or phone, however, it's much easier to use on a laptop due to screen size.
I am able to conduct business, receive faxes, scan items, edit forms, and more while on the go. This makes life a BREEZE! I am never really disconnected from work unless I choose to be.
I would say the monthly payments are ongoing and never end. In real life, things like software have a finite value, however, I haven't seen an all-inclusive tool for less.

Great to use especially working from home
I have been working from home and Sarah PDF has been trying amazing. It is very easy to use and the way I am able to merge my documents and download them is great.
2024-01-17
What do you like best?
Ability to edit pdf files and general ease of use
What do you dislike?
Limitations on how many files I can upload and the fact that it opens the files immediately, If I want to merge a newly uploaded files with previously saved files on my dashboard, it creates some unnecessary steps.
What problems are you solving with the product? What benefits have you realized?
Not really any problems - just a few areas the program feels clunky.

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.
