What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I used PDF filler to complete a URLA form because the one I was sent by a loan officer was so small I couldn't fit the information in it. PDFfiller made it very easy for me to see and complete the form. I feel that this service would be good for a small business owner because there are many documents available as well as documents that explain the documents you are completing.

Great for my online classes!
This has been a great tool for editing PDFs for my Anatomy class. The only problem is the "drawing" tool does not provide enough color options. It's very limited.

Scanned Editable Documents
This has enabled me to quickly take scanned business documents and turn them into editable documents that can be filled in repeatedly. Such a time saver.
2019-03-08
The program is easy to use for searching for forms or updating my own documents.
The program is easy to understand and use. It is intuitive for anyone used to editing documents or creating forms.
I would prefer better opportunities to edit changes while in the same document. It can be challenging to erase and re-enter information.

What do you like best?
I like how easy it is to upload documents and make the necessary changes to the documents that require modification. I have completed forms for students and uploaded signatures easily and have been able to successfully download documents as well.
What do you dislike?
I have noticed that sometimes when I upload a document that I previously edited using PDFFiller, it makes my signature super bold and not easily read. It changes the format automatically and I have to download a new document to upload and add a signature. It seems like once I utilize PDFfiller and download the document the format of the previous e-signature is no longer compatible.
What problems is the product solving and how is that benefiting you?
We had to provide e-signatures to international students on their I-20 documents and PDFfiller has been an integral part of that process. It has been very accommodating for me to upload documents and sign them electronically for students and then easily download them and email them back to the students.

PDFFILLER
PDFFILLER, I have tried many and many have failed, typically to overstate and underdeliver, however. PDFFILLER, is the nerd in the room understated but delivers at every turn. There have been times though that I was sure they misssed something, that is untill I call support and talk about delivery. A product is only as good as the support team behind it. Hours spent trying to figure out this glitch, testing this and testing that, and the support agent just as friendly and helpful at hour three as at hour one, come to find out, it was my network, my VPN and firewall wasn't letting me upload documents, others were good and worked fine. except from my phone. Even then the agent was doing even more testing and providing his findings via screen recordings over email. I was amazed and it wasn't the first time. incredibly knowledgeable and professional. I am not an easy person to please as most software isn't completly vetted before release but PDFFILLER has done their work and worth every penny.

What do you like best?
It is very user friendly. It has a lot of features that I constantly use. I have expanded from a one user account to a multi user account becasue the product is so good.
What do you dislike?
Nothing really. I am able to youtube anything that I don't understand and typically get it.
Recommendations to others considering the product:
Get it while you can as it will be a major help to automating your systems.
What problems are you solving with the product? What benefits have you realized?
Being able to change PDFs and being able to electronically sign documents.

PDF Filler is a great website for me to…
PDF Filler is a great website for me to use. It's simple and convenient since I don't need to fill everything by hand. The only issues I have are filling in the date because I'm required to manually select the day, month, and year. Another issue is the website automatically switching to the next page which is annoying because I want to check all the fill ins are correct. Lastly, the layout of the website is rather confusing because I had to spent a couple of minutes figuring out how to import documents and other stuff. That's why PDF Filler gets a 4 star rating because of these mild inconvenience.
