What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I am only done with one of two multi paged forms.I was very thankful to be able to fill out some very long forms with a computer rather than free hand.

I fill out a lot of forms from different organizations. Found PDF Filler after searching for a federal form. It was the top result and I started using it from there. Some organizations do not even realize how they have deployed PFD files. When you show up, or fax them their completed PDF file you get some odd reactions.

PDFfiller has been an excellent tool for both personal and professional uses. I especially like that I can send documents and get a confirmation receipt once the recipient downloads it.

ecame aware of PDFFiller in March 2018 and learning how to use. Would like to attend the Webinar ASAP. I cannot open a document because you asked for a pin code sent to me by email. I have not received any pan please re-sand pin code.

I had a difficult time with it and it took a long time just to fill out passport forms for my wife and I. I just could not get the hang for it, but someone smarter than me and maybe younger, I am 72, will do much better with PDF filler.

Kara provided great tech assistance and she was polite, friendly, knowledgeable, and patient. The 4 stars is for Kara. The company on the other hand... not so helpful. They are great at marketing their product but provide very limited and nearly useless resources for helping their subscribers troubleshoot issues and/or educating the consumer on the tools and functions of the product. The company YouTube channel spends about 30 seconds on "how to" and the remainder of the video is promoting the product. Seriously, every single video, watch for yourself. All fluff and no substance.

Thanks

I wanted to use this tool temporarily because I had to sign a lot of documents at the time. I kept it and use it for a lot of things now! Its very useful and worth the money.

I have found the software to be easy to use and has features that similar sites don't have. I have not yet spent much time to learn all of its features but I plan to. I would like to create forms and sell them on your platform. I would like to create some form that would allow a business to evaluate and identify its essential functions so that they may operate efficiently in times of, say a global pandemic.

What is age standardized rate?
An age-standardised rate (ASR) is a summary measure of the rate that a population would have if it had a standard age structure. Standardization is necessary when comparing several populations that differ with respect to age because age has a powerful influence on the risk of dying from cancer.
What is standardization in epidemiology?
Within one population, it is common to summarize disease burden with the number of cases. A standardized rate is a measure of disease frequency that facilitates comparisons of populations with a different distribution of one or more potential confounding variables.
What do you mean by standardization?
Standardization is the process of developing, promoting and possibly mandating standards-based and compatible technologies and processes within a given industry. Standards for technologies can mandate the quality and consistency of technologies and ensure their compatibility, interoperability and safety.
What is standardization with example?
From a business standpoint, standardization refers to the practice of maintaining some level of consistency in the product or service that a company provides. A company wants to produce a consistent product, so consumers will know what they're buying. Say, for instance, a bakery produces loaves of wheat bread.
What is the purpose of standardization?
Standardization is the process of determining the exact concentration (molarity) of a solution. Titration is one type of analytical procedure often used in standardization. In a titration, an exact volume of one substance is reacted with a known amount of another substance.
What is standardization in research?
Standardization refers to methods used in gathering and treating subjects for a specific study. In order to compare the results of one group to the results of a second group, we must assure that each group receives the same opportunities to succeed. Standardization of the research methods is often a lengthy process.
What is direct standardization?
The direct method of standardization requires that the age-specific rates for all populations being studied are available and that a standard population is defined.
What is the difference between direct and indirect standardization?
In indirect standardization, the weights applied to the standard age-specific rates depend on the age structure of the study populations. Direct standardization requires that we know the age-specific rates of mortality (or morbidity) in all the populations under study.
