What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
At first, I was disappointed by the service. We needed to fill out a rental application and have been very stressed. We found this website which seemed to be a dream come true. After having filled out all of the painstaking details, found that we had to pay to be able to fill out a document online. This was very frustrating. However, a customer service representative quickly resolved our issues. Thank you.

When I started searching for a PDF to Word doc. a few days back, I downloaded 4 different trials and hated all of them!! They were not user friendly like this one is!! To anyone reading this, DO NOT waste your time researching other apps, you will not find anything better then this one! I would absolutely recommend PDFfiller to anyone who is reading this!!... and so will you.

I'm happy with it for the most part. I think it's BS that you allow the eraser to be used on the 1st document and only when the customer goes to use it again, do you mention that it's an upgrade is bad business!!!!!! There's another issue but at the moment it escapes me.

It is a little bit confusing on how the program works. I have been trial and error learning so far. It would be nice to get more direction and not just comment bubbles.

Just like last year!
I must file my church's taxes for our employees every year. I found this site last year. I love it! I prints the information I need. I can make copies and send it. I could send directly to IRS but chose not to do that route!!

I recently started a trial account with pdfFiller but it wasn't quite what I was needing. I didn't cancel the trial correctly so when my Debit card was charged I immediately contacted support and they resolved it within about an hour!

Easy PDF
PDF filler is undoubtedly among the best software I have used for manipulating PDF documents. Easy to use, it offers many features and is less expensive than other software competitors. The only real flaw in my opinion is the lack of clarity about the free trial. The user can modify his document and only when downloading it he is asked to register with a payment method. This can be confusing and irritating if you don't know it beforehand.
easy to use
accessible from anywhere
includes many features
there are often problems with payments
there is no clarity on the 30-day free trial

Fairly easy to use. Would like to combine 2 or more docs into one file so I can fax as a group. I'm sure that's an option; but haven't found it yet...still new at this.

What does it mean to optimize a PDF?
Answer: To optimize a PDF usually means to reduce the size of the files so that they are more optimal for Internet use. If you work with PDF files, there is a good chance this will be useful to you. By shrinking the size of the file, you can now send the PDFs as email attachments or even a bulk of them.
What does optimizing a PDF do?
Most PDF editing/creation software offer an option called Fast Web View or Optimize that allows PDF files to display the first few pages of the PDF file when the document is opened, instead of waiting for the full file to be available. Optimized files are also generally smaller than non-optimized files.
What is the difference between PDF and PDF optimized?
Reduce Size PDF is one particular set of settings of the Optimizer. And it is some average setting, but it may or may not really work for you. Optimized PDF is controlled via the Optimizer, where you have full control over the settings, such as image resolution reduction, font embedding, etc.
How do I make a PDF file smaller, so I can upload it?
Locate the PDF file you want to make smaller.
Click on and hold the PDF file.
Drag the PDF file to the Drop PDF here icon on the screen. The file will upload and begin compressing.
Scroll down and click on Download File Now.
Select the location where you'd like to save the file.
Click on Save.
