What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
Used PDF Filler to create 1099's for caregivers for my aunt and uncle. It was a good experience overall. I wish that I did not have to re-enter my information again for each of the 1099's.

I bought this to use at work. It's so easy to use and keep documents looking professional. It's nice that it's cloud based so I can use it when working remotely as well. The mobile app is great too. A great resource for a great price.

What do you like best?
Changing things (like dates) on insurance forms helps us a great deal when the insurance information stays the same and only the date needs changed. (Accord forms). We don't have to completely retype an insurance renewal form. So Handy
What do you dislike?
I have helped a colleague in inputting his information on flyers that had someone else's and the eraser showed lines in the final product. I had to figure out what was going on and I figured out I could increase the eraser to remove items rather than going over it several times (like wite-out tape).
Recommendations to others considering the product:
If you need to make changes to documents that you do not want to retype over and over again, then this product is a handy tool. Also, for doing 'already-made-up-flyers' to use for yourself by adding your own information is great. I used to have to remake everything with Corel Draw. This is waaaaaaay easier!!
What problems are you solving with the product? What benefits have you realized?
Non really for what I use it for.

As a freelancer I use PDF Filler to complete W9 forms - it's great!
PDF Filler is simple, easy to use, and creates professional documents that are easily accepted by employers and large corporations.
The exporting workflow is a little confusing - at least for their IRS W9 Form. Instead of just pressing a button to save the file to my phone I had to email it to myself in order to obtain it. This may have just been my ignorance, however. All in all, PDF Filler is a great help!

This application saves me significant amounts of valuable time in the clinic
The most desirable feature of this application is the time that it saves on recurrent clinical and axillary paperwork for my clients
The most tedious aspect is searching for past documents which dont seem to search by just part of the title

How do you find the sum of a log?
A useful property of logarithms states that the logarithm of a product of two quantities is the sum of the logarithms of the two factors. In symbols, logo(XY)=logo(x)+logo(y). (x y) = log b (x) + log b

What happens when you add logarithms?
The laws apply to logarithms of any base, but the same base must be used throughout a calculation. This law tells us how to add two logarithms together. Adding log A and log B results in the logarithm of the product of A and B, that is log AB. The same base, in this case 10, is used throughout the calculation.
How do you add natural logs?
A natural log is just a logarithm of base e, that's all. (1 + 1/n) ^ n. In any case, you add and subtract natural logarithms (log base e) just as you'd add and subtract any logarithms. Log(A) + log(B) = log (A + B) log(A) — log(B) = log (A/B)
What is the formula for log a log B?
The identities of logarithms can be used to approximate large numbers. Note that logo(a) + logo(c) = logo(ac), where a, b, and c are arbitrary constants.
What is a log divided by a log?
Division. The rule when you divide two values with the same base is to subtract the exponents. Therefore, the rule for division is to subtract the logarithms. The log of a quotient is the difference of the logs.
What is the log rule?
The logarithm of an exponential number is the exponent times the logarithm of the base. The logarithm of a number that is equal to its base is just 1. Rule 6: Log of Exponent Rule. The logarithm of an exponential number where its base is the same as the base of the log equals the exponent.
What is the addition rule for logarithms?
The rule is that you keep the base and add the exponents. Well, remember that logarithms are exponents, and when you multiply, you're going to add the logarithms. The log of a product is the sum of the logs.
