What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
Overall easy to use, however, there are instances where the edits on the pdf become warped, other times its difficult to remove words or characters. There should be a save option versus a Save As, as that navigates you to another screen. Or have an auto save option. Overall good program but still has small defects.

The experience before I purchased a license was not so good. The chat session I was on kept ending. The CSR said because I was not logged into an account was the reason. At that point, I was trying to determine if I even wanted to purchase PDFfiller or not so why would I need an account. I finally ended up purchasing the product.

I wish I didn't have to pay. I would have found another free site, like going to SSI site, but I had already filled in all the blanks and it was so time consuming that it wasn't worth the effort. I will cancel as soon as I get the bill.

I was filling out a stubby pencil application, and thought there has to be a better way. Now I'm happily dragging and dropping scanned files into PDF filler and like magic I have an automated workable document, it's fantastic.

I just was able to get the best service ever from Paul. I found I did not use this service as much as I did in the past, but the automatic renewal of payment had gone through. I contacted CS via Support and received a FULL Refund and cancellation of Auto Pay with in 3 minutes flat. Furthermore, received an email with confirmation of my request!! This is the way to do business!! Thank you for making the refund process painless!

PDF Filler is a must for me!
I love it! As a small business owner who strives to maintain a professional business image (website, business cards, etc.) , PDFfiller does just that for the proposals I create for my customers ... both future, and repeat. I know for a fact my customers appreciate the quality and professionalism of the proposals they receive from me - they've told me so! Thanks PDFfiller!
I love the ability to quickly, and easily, create/copy professional proposals for my customers. I then save each file as a PDF (with my logo embedded at the top left of each document), and attach via e-mail for completing my estimation process with each customer.
The only thing I've discovered is with the particular template I use for my particular proposals - my template has an area that indicates "Page 1 of _" ... well, there are no additional pages that are affiliated with my template, so I end up either having to re-edit to ensure my entire proposal fits into "Page 1", or I have to continue additional pages outside of PDFfiller.

Its a little bit hard to email the documents back to yourself after the conversion - otherwise, this is a great website for document alterations and conversions. Easy to use, great variation of different tools and mediums.

How do you sum 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
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 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.
How do you add logs together?
Logs of the same base can be added together by multiplying their arguments: log(XY) = log(x) + log(y). They can be subtracted by dividing the arguments: log(x/y) = log(x) — log(y).
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.
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.
