What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
The UI is outstanding and very effortless. Very impressed.
My only issue was with advanced features. Would have liked to know ahead of time that they were additional fee. Everything looks included and don't like being told something cost money after the fact. Second, when telling me I had to upgrade to get additional feature, it should show the difference between what I am paying verses the new amount. I was on personal plan ($6) but to get the features I needed it was ($10). It said it was $10 for advanced plan but I didn't know if that meant $10 MORE than I was already paying. I had to open site in incognito mode, look at plans to figure it out... not fun.
Lastly, I was trying to send 2 separate PDFs as one doc. It took me a while to figure out where Merge was. I didn't understand why all the options under Actions were greyed out. That was very frustrating and should be improved.

Simply put, PDFFILLER has made my life a whole lot 'simpler'. I am no longer buried up to my eyeballs in paperwork (just up to my knees now! ha!) Since i began using PDFfiller, my desk is now, finally, Organized! Before PDFfiller - you couldnt even see the glass top on my computer desk., but now, since using PDFfiller, you can actually see every square inch of my desk! there isnt a single piece of paper 'waiting to be scanned', or filled out, so on and so forth. Which obviously has a huge impact on my ability to stay on track and stay focused! Needless to say I absolutely LOVE pdffiller! NO REGRETS!

Using this site to fill out divorce paperwork. Sometimes the text is too big for the field I'm in, but other than that I think that the site is awesome.

I absolutely LOVE PDFiller! That is the honest truth.
I truly do. You have no idea. It's easy to use. It does and has everything you might possible need to do to a document. It's amazing to say the least.

Great software. Only thing is that i wish the email could be modified to where i can get paperwork sent directly to it. The automated one we're given is way to complicated to remember so copy and paste it is. Other than that this is amazing software.

What do you like best?
PDF filler has allowed me to not only make forms being filled out easier but also allows me to keep them archived on their server so I had don't have to look for them.
What do you dislike?
I think the only downside I would say is the send to sign can be a little confusing. Some of my clients have had issues trying to sign things when I've used this feature.
What problems is the product solving and how is that benefiting you?
The only time I've had issues is when a form wouldn't load to the system. Customer service has always been great helping me out. They usually have the problem resolved quickly

I've used this software before, but I find Pdf Filler a bit better for my use. I need to learn the software better, because if it continues to help in my work I will be a loyal client.

Works well
Works well. Just wish there was a way to sign without the added date and time and logo. No one cares about the logo, they just want a signature that appears real. I still have to print, sign and scan, because of that one issue. Kind of makes it worthless to be able to fill out on line.
