What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I didn't know working with *.pdf files could be SO EASY. PDF Filler allows me access to any form I need and to copy all text from page one and paste to all other pages so I only have to complete the form once.

This program has helped me with all my dreams and aspirations of making money BIG TIME since enrolling in this site I have made over 150k thanks guys.
2016-02-11
I like the program, but I really needed the ability to add Bates Numbering.
If the program would overcome some of the rather important limitations, this would
be an excellent deal for the money.

9/15/16: Hard to find blank forms for completion, but questions are covered well by support folks. Default is yearly subscription, but support folks were able to convert to monthly subscription at desired level.
Problem with changing previous form required upgrade to yearly business plan. The erase tool only works with upgraded plans.
2016-09-25
It's easy and I use it for billing for my private practice. There was a recent change in the function of the program that you have that has caused me extra time. I used to be able to look up my form by name using the little magnifying glass and then when I found it, click on the form, and then click on the copy icon. The copy icon isn't present anymore when I look up the form by name, so I instead have to scroll back through all of my forms and it takes a lot longer. If I could still look up by name and then copy the form once I found it that way it would be great. I used to be able to do that until the recent formatting changes.

ONE OF THE BEST PDF FILLER'S IVE USED…
ONE OF THE BEST PDF FILLER'S IVE USED SO FAR. SOMETIMES THE FONT LOCATION/SIZE WILL PRINT DIFFERENT THAN IT APPEARS ON THE SCREEN BUT AN ADJUSTMENT OR TWO WILL TAKE CARE OF THAT.

When I asked about sending my documents…
When I asked about sending my documents via email, 1st.person sent me a link to put my card# and 1st.month free.I didn't feel rite doing that,being that the documents I was trying to send were about fraudulent use of my card.So sumbody else got on chat and was able to let me send it for that day only,just to show me how your comp.works.And because of that I will be using pdFiller from nw on.TANKYOU TO WHOEVER DID THAT.I APPRECIATE IT VERY MUCH.
2023-10-01
Great, this time so far. I used the program a little over a week ago but my documents were messed up because I was not told I had to pay first in order to save or print the document. I had to create it all again. It was the same one as this now, 821 ssa form. It took me hours to get as far as I had.

Basic PDF Editor
I use it for PDFs for our Escrow files. We have clients sign docs and we can make changes to anything that they send us and then send to them to sign off on it
It is easy and very good for a basic PDF editor. You can make simple changes and save it so it looks exactly like a PDF should. You can add and edit text, highlight, adjust sizing, etc.
It is too basic but i understand that it is not Adobe. I wish I could edit the text that is in the PDF more easily to make it match and all look seamless

Calculations in a PDF
When you are a student, banker, accountant or actuary, you spend much time on different calculations. The Add Fillable Fields feature allows you to insert different types of fields into your PDF or Word document and do complex calculations. Transform any document or form with smart digital fields using the drag and drop wizard.
To get started, upload the document to your pdfFiller account and open it in the Editor.
To create fillable fields for formula, click on the Add Fillable Fields tab on the right.
When the tab opens, you see different types of fields that you can add to your document. To add the Formula Field, select Formula.
Drag and drop the selected field anywhere on the document.
Open the Formula Builder at the top of your document. It will help you calculate a value based on number fields in the document.
Resize the field by dragging its corners or edges. Use the text formatting tools to preset the field’s text format including the font, size, color and alignment of text. Change the format of the calculated value by clicking Format on the right. Click the Save orange button in the top right corner to save the changes.
Once you’ve clicked Save, you will see the calculated value on the place where you’ve dragged and dropped the field.
To delete a fillable field, click on the trash can icon above it. You can customize any fillable field. Click Advanced in the right pane and select the options you need.
After you’ve added the Formula Field to your document, you can edit your document, sign or send it to be signed and share. When you’ve finished, click the Done orange button in the top right corner.
