What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Limited capabilities on iPad. Would be nice to have drawing tools on iPad. Also can't copy and paste between two forms, so if you need to have the same info on two forms, it's somewhat cumbersome. That said, not bad for the price.

As a beginner, I would like to learn and practice some other functions. My favorite part of PDFfiller is I can sign the document either by type in my name or just tip my finger.

I need the valuable options to verify signatures and to easily file paperwork with government institutions. PDF is "Pretty Darn Fly." (Not professional, but true)

Ease of use is great because I am a one-person office, and don't have access to a lot of office machines, so this works good. I just have to figure out how to get it to scan.

What do you like best?
Easy to use but comprehensive options for editing. Quick and efficient which is important with time sensitive docs and a busy life. Some recent new features tells me the company is progressive. I was having technical difficulties one day and support was responsive. I've tried numerous PDF/Editing programs. and this is by far my favorite. It's web based not some ap that you have to download that later crashes your computer. Can access it from any PC so that helps too.
What do you dislike?
The price is substantially more that I'd like to see. Takes a bit to save file to PC once done editing. can be a little slow at times but still a reliable tool I use at least weekly if not daily. Something in the $50 range would be delightful and it's well above that currently. Maybe efax for this price I have not used the esign feature yet so maybe will try that given our member benefit program is lapsing.
What problems are you solving with the product? What benefits have you realized?
Quick way to edit and correct documents. Easy to save and access later. Lots of options for composing sending and revising. I only use basic functions but there are several ways to use this valuable tool beyond the features I use that exceed other competitors.

I had some slight issues on my 1st… I had some slight issues on my 1st attempt as there were fields in different locations than a previous edition of this form, but easily was able to correct the overwriting of several fields. Worked beautifully on several previous (new) documents.
