What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I was please to see that I could edit my spreadsheet. I would suggest that once a work or set of numbers are highlighted that the program automatically is able to identify the font and size of the writing. Otherwise I was very pleased.

Very useful. Would like to see a Strike-Through option where the user can highlight a section of text and select the Strike-Through option to strike through the selected text. Thanks!

I signed up for the free trial and was…
I signed up for the free trial and was able to amend 2 documents with ease.If I had the kind of life that required me to need further amendments in this way, this service is absolutely one I would use. Thing is, I just don't, so I didn't sign up after the free trial! Had a little difficulty cancelling the subscription, but honestly - I think that was 'on me', I just wasn't entirely sure what I was doing.However, it's a great service and the company responded to my concern when the subscription fee was taken by emailing me back and confirming that they would be refunding the cost. So, I think you can trust this company.

Perfect for my needs!
I found it super easy to use - was looking for a product like this and it really met my needs! I have used it for basic tasks and it works great.
I feel like if I ever want to do more creative documents that I will need more training. This feature is a bit complicated to me.

Great and simple pdf editor
Easily edit, share and secure pdf documents.
This is a basic pdf editor that does everything I need. You can edit by adding text, making notes, make tables, add a signature area, etc. It is also very secure and easy to share and collaborate. Even the free version is awesome.
It's not the fanciest, smoothest software but it gets the job done. I would like to see the interface beautified a bit.

A good pdf editor, although there is still some work to do with the command consistency with the environment (windows keys, for instance while editing a document if we press home the screen goes to the header of the document).

I immediately was connected to a support person via chat, and he walked me through what I need and was very professional and supportive. I truly had a great experience.

What do you like best?
Definitely needed for any business that handles a lot of paperwork. We use it on almost a daily basis to fix or change a document that may have been mis-written and it is very easy to do this with PDFfiller. The ease of use is fantastic, we recommend it to everyone with a business.
What do you dislike?
I wish there were more options to match the color of the page when you erase something. And more font options to match the current font on a document. I also wish it was easy to upload multiple documents to create one solid PDF. That is one thing that I would like to see in any new updates. Also the system could possibly use a style refresh. It does seem a tad outdated looking, but that does not affect its usefulness.
Recommendations to others considering the product:
Just use it! It is worth every penny if you need to edit any documents
What problems are you solving with the product? What benefits have you realized?
Easily fixing business documents. Very smooth and easy to use. We are able to use this system to edit documents on a daily basis. We love that when you erase something you can just type right where you just erased so it matches the lines perfectly. It also makes it easy to fix boxes and add signature lines. It is also very smooth to upload documents and edit them. Definitely appreciate this system very much and we would recommend it to everyone we know.

What do you like best?
This program makes it very easy to enter data into pre-printed forms instead of using a typewriter.
What do you dislike?
Sometimes there will be a data box over another data box and it makes it difficult to change information. Also, when you highlight and change or add to preexisting words the formatting changes and you can not change it back to look like the original
What problems are you solving with the product? What benefits have you realized?
Not having to ever use a typewriter is the best benefit. Having all of my previous files stored is highly appreciated.
