What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Works well but continues to have security issues in connecting with my Google Drive account. Each time I open a PDF in Drive using the PDFFiller App, I get an Unsafe warning. Please clear this problem up. I don't have the time or energy to do your survey right now, perhaps in the future.

What do you like best?
PDFfiller is easy to use and has widely varied functionality. From the editing of documents to the administrative/management aspects of the program, it is quick and simple
What do you dislike?
Some elements of the interface gets a bit busy. It ends up leaving me with a somewhat small visual operating space. It is worth mentioning, though, that this has improved a bit in the last six months or so.
What problems are you solving with the product? What benefits have you realized?
I'm using the templates to edit and send out letters, which I like. I'm also sometimes using the direct email function.

PDFfiller Fills Needs My overall experience has been positive and if the cons are minimal. It's easy to use and allows me to make necessary additions or changes to documents with a minimum of fuss. Sometimes getting the font to match is a little challenging, but it's easier than trying to "fix," documents with white out and hand print information.
