pdfFiller scores top ratings on review platforms
Using iPhone to complete apps and send out for signature.. Had some glitches.. Wasn't able to select or choose (full access or sign only option for recipients. The screen shut down too quickly each time and 'disappeared before I could actually select.
I've enjoyed editing a pdf calendar with my families birthday and anniversary dates to gift this Christmas. Editing was a snap and I have saved my work so I can add more info if needed.
Has many great tools, but a little difficult to navigate, not clear instructions. I am sure I am not utilizing half of the features, it is trial and effort, not all successes, but slowly figuring things out.
Perfect for paperwork
My overall experience would be that I love it and plan to continue using it going forward in life. It's much easier then printing out paperwork, filling it out, scanning it and sending it back to whomever. Its extremely convenient.
I love most that I'm able to edit any pdf and the save and and either email it or print it. There's even a function to sign the pdf right on the computer. Awesome.
I do not like that it sometime freezes. I could be filling out a form and sometimes it'll freeze and automatically refresh and everything I put in is gone so I'd have to start over. It doesn't happen often but has happened to me before.
PDFfiller Review
In my job, we send out contracts and W-9 forms to meeting attendees all the time. PDFfiller is great because attendees can quickly "sign" and send their documents right back, without having to print the forms, sign them manually, and then deal with faxing/scanning/or taking a picture to send it back. I like how seamless PDFfiller is.
Sometimes, the actual signature does not populate, and all that shows is a stamp saying the person signed it. However, with things like contracts and W-9s, we need an actual signature, whether it be manual or digital.
PDF Filler Beats Adobe Sign For Me
I have used PDF Filler for about three years now and their customer service and platform are wonderful. Previously, I was using Adobe Sign but I found it way too expensive and cumbersome to use. Their customer support team always seems to be available and if any issues arise, they get solved quickly which is very important for me as a business owner. I highly recommend them.
Amazing product and service
Amazing product and service. I had an issue with their billing, and it was literally resolved in 2 mins! No kidding. The product is also really useful if you have to deal with PDFs frequently.
Ryan on the Support Team was extremely helpful and patient. He walked me through all of the steps to complete the form to my satisfaction. Thank you Ryan for teaching me!
Still learning... but so far so good.
Convenient user interface, able to quickly make the necessary edits to my documents and I'm enjoying using the product.
