It's excellent! Saw Vadim talk when @ TS Boston and switched over from docusign. Personally think that everything about pdffiller is better and would never go back. Highly recommend pdffiller to all of my friends.

I like the service just wish the process of saving and/or printing docs wasn't as cumbersome - two or three pop up windows before action is completed and not automatically redirected to doc list.

It works great, but is very expensive for how often I will use it. I wish there was an option to purchase some sort of punch card or to pay per use instead of paying $20/month, which is outrageous if you are not using it daily.

Thank you for your services Thank you for your services! I’ve been working on a very important document to correct my military records, for seven years I’ve been working towards correcting an Ilegal discharge from active duty from the Army. In February I received news that changed my while direction so I started over from scratch. My draft is now complete and now I have all the evidence and events storyboard complete. There was a very important PDF from 2012 that is no longer available on the .gov website so I resorted to Google and found it on your site. Your site helped me to gather the necessary blank PDF forms that proved they did indeed break thelaw. It was a lifesaver for me!

The best PDF converter Excellent. My current job is as freelance translator, and sometimes my customers send me the documents in PDF. for me, it's easier to work with WORD format. You can convert any type of file into editable one. In case of scanned PDF, it doesn't work.

Easily Add and Delete Pages From PDFs PDFfiller has saved me a lot of time combining PDFs and adding/deleting pages. Definitely a must have software. I like that I can easily add and delete pages from PDFs. They also make it super easy to combine PDFs together. Overall, very happy with the platform. Might be nice if there was an option to upload and download to Google Drive.
