As far as I have been using it it looks nice, the only problem that I found was when I choose to convert my pdf into a word document some letters and format change or is missing.

It's not as easy to follow as you think it is. For example, Save As is a command that most of us think as a file name, not application such as PDF or Docx. I now have to go back and find the document, add the signature and then, change the name of the file, somehow from the template to a specific client's file.

all the features save so much time! and the price of using them at first seemed ridiculous, but once you realize how much time and effort this can save you the price automatically becomes such an amazing deal.

Needed to attach a photo to a PDF and found PDF Filler such an easy and quick site to use to satisfy my needs. My acting resume now looks even better with a headshot!

Time is Money
The document import feature, text alignment tools, and being able to directly type into the document has saved me a lot of time hand-writing statements. This is a good product. Thanks!

PDFFiller saved my books!
PDFFiller saved my books! As a young author, I had no idea what I was doing and deleted my original documents once the books were published. I only kept the print-ready PDFs. Years later, I realized there were a lot of spelling mistakes and errors in them, and wanted to re-publish. Since the books had photos, I couldn't simply convert to a doc. Most PDF tools online didn't work, or put on watermarks. PDFFiller allowed me to edit the text in the PDFs, to correct the spelling mistakes, and merge the documents into one cohesive PDF again. I was able to republish an edited book without the original documents, thanks to PDFFiller.
The one thing I missed that could make this a fantastic tool- the original book was 8.5x11. I wanted to republish at 6x9. I ended up having to resize it through a different tool, which simply shrunk everything instead of being able to directly resize the content. Due to that, the book appears much smaller on the pages than it should, and I've received some complaints that it's harder to read. If PDFFiller had a viable PDF resize tool that worked to resize the content versus simply shrinking the document, it would be a stellar addition to the repertoire.

Took a bit to find the "how to use Zapier" tricks (Zapier had a link), and to learn how to use Fillable Fields properly. However, once over that hump, this service is fantastic. My workflows will be faster and cleaner from this point forward!!!

Other than being billed initially for a 30 days trial, I contacted Customer Service right away and they credited me back the $144 first year right away. Otherwise, I am liking the service so far. Just learning how to use it.

I used this product to edit and fill out an application and found the software to be very easy to use and very effective!
I unfortunately forgot to cancel my 30day free trial and was unexpectedly hit with the charge the week before payday when I really couldn’t afford it.
I explained my situation to the customer support team via chat and they happily refunded me my payment!
Could not be happier with the service they provided and the understanding of my situation.
Would definitely recommend!
