Initial rough start when my first document could not be converted to PDFfiller format & problems setting up an account password, but that is behind me now and application is working as advertised.

Great features, love the ruler that lets you type straight every line unlike Adobe Acrobat. I really like the compatibility with mobile phones to create your digital signature. Overall I was quite happy and impressed with the software. It would be great if the trial period was longer.

What do you like best?
PDFfiller is easy to use and has widely varied functionality. From the editing of documents to the administrative/management aspects of the program, it is quick and simple
What do you dislike?
Some elements of the interface gets a bit busy. It ends up leaving me with a somewhat small visual operating space. It is worth mentioning, though, that this has improved a bit in the last six months or so.
What problems are you solving with the product? What benefits have you realized?
I'm using the templates to edit and send out letters, which I like. I'm also sometimes using the direct email function.

PDFfiller saved me significantly more than the cost of a subscription I found PDFfiller when searching for a (lease) document I needed to complete for a potential tenant. I signed up for the trial, and I will let it continue to a paid subscription. PDFfiller saved me significantly more than the cost of a one-year subscription. I'm really happy with the program, which allowed me to customize the document, and easily fill out the form.

Well laid out, easy to use fillable pdf program Just downloaded this program and am impressed already. It's well laid out, easy to use, and overall a great experience. It's nice to be able to turn non-fillable pdf's into fillable ones.

PDF filler is VERY easy to use PDF filler is VERY easy to use. The only sticky point for me sometimes is finding forms. There is a library connected to the app but I often find the forms there confusing. So I google them and import.

Great software for the money Great software for the money. Has helped tremendously with our business needs. The only thing I would change is the LinktoFill. This gets confusing due to saving a file when you make updates to it and then you end up with having the two files. there should be an option to update exsiting file. Besides that, great program.

In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x.
The number whose logarithm is a given number. For example, the logarithm of 1,000 (103) is 3, so the antilogarithm of 3 is 1,000. In algebraic notation, if log x = y, then antifog y = x.
An antifog is the inverse function of a logarithm. ... However, you still see the term “antifog” used in electronics for components such as antifog amplifiers.
To calculate antifog, plug the number you want to find the antifog for into 10 to the x power, where x is equal to the number you're working with. For example, if the antifog is 10^2.6452 use a calculator to find the answer, which is 441.7.
An antifog is the reverse of logarithm, found by raising a logarithm to its base. For example, the antifog of y = log10(5) is 10y = 5.
STEP 1: Replace the function notation f (x) by y. STEP 2: Switch the roles of x and y. × y. y ×. STEP 3: Isolate the log expression on one side (left or right) of the equation. STEP 5: Solve the exponential equation for y to get the inverse. ... Kate is not defined.
Put in the base number e on both sides of the equation. E and LN cancel each other out leaving us with a quadratic equation. X = 0 is impossible as there is no way of writing 0 as a power. Put in the base number e. LN and e cancel each other out.
STEP 1: Replace the function notation f (x) by y. f (x) y. STEP 2: Switch the roles of x and y. STEP 3: Isolate the log expression on one side (left or right) of the equation. STEP 4: Convert or transform the log equation into its equivalent exponential equation.
enter the number, press the inverse (in) or shift button, then. Press the log (or LN) button. It might also be labeled the 10x (or ex) button.
Type the number you're working with into your graphing or scientific calculator. For example, type “1000.” Press the “Log” button on your calculator. The number you immediately see is the exponent for the original number you entered. ... Check your work.
