What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
Blown away. EZ to use once figured out, and quite intuitive. Only a couple surprises where the DOS commands didn't always work e.g. cut and paste. The shift/delete cut worked, but the shift/insert paste didn't. Just need a little time to find my groove. All I can say right now is: Bye, Bye handwritten forms. dc macdonald

It was really easy to modify the text but it didn't allow for modifying the form itself. When I ran out of blocks (Employee Review Form), I couldn't add any lines to the bottom or even take away some of the "Reviewer comments" to give me space to add more lines for categories.

I really liked the entire PDF Filler platform! The content was laid out clearly and it was really easy to get started (even when I was frazzled about other things). Working with the platform in seamless and I have already recommended it to my mom who uses PDFs in her company 24/7

This was a great program
This was a great program. I just don't use it enough to justify paying annually. I wish there was a charge per file option.

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!

A Great Time Saving Tool
This software is a great time-saving tool in that it allows me to fill in, search, and edit forms and send them electronically within minutes. That way, I don't have to manually hand write information the form, then scan them (or mail them) and wait for recipients to respond. The software basically digitizes the workflow process, which saves me a lot of time.
The software is limited to specific industries and the forms and features that these industries use. Therefore, not all forms and features are fully applicable to our company so we can't take advantage of them.

Pdf filler is better than Adobe
Good for small simple doc editing. Adding signatures etc.
I was able to get my docs edited and printed with my native software and android phone. Adobe is too picky about using their product only, with PDF filler I was able to get everything done non issues.
It was a trial basis for free, I wish they would have told me that from day one to save me the hassle of going back to purchase, but really it didn't matter.

Great app
Great app - really easy to use. Doesn't change the quality of the document. Probably won't pay for it long term - I would pay £1 or something everytime i wanted to use it though...

I made a mistake and bought a year subscription instead of one month as I needed, I immediately emailed customer support and thought I would be waiting days for a reply if I was lucky, but to my surprise I received a response within 2 minutes. She offered to change my subscription and refund the rest of my money, I of course excepted and they changed it immediately! ***** ******** for your amazing customer service! And your forms, that have been time saving!

What is the log formula?
When we take the logarithm of both sides of ELN(XY)=ELN(x)+LN(y), we obtain LN(ELN(XY))=LN(ELN(x)+LN(y)). The logarithms and exponential cancel each other out (equation (4)), giving our product rule for logarithms, LN(XY)=LN(x)+LN(y).
