Great tool
Easy to use and has functionality I need.
Think there is some maximum number of pages you can convert at one time so have to break it up.

Best program Ever!
This software has changed our business. We are in a very form intensive business and not all forms come in electronically. PDFfiller allows us to convert them and manipulate them to our liking. Saves us tons of time and effort.
Nothing I don't like. This software has allowed us greater efficiency, allowing us to focus our time on other things.

Excellent service
I had signed up and not cancelled the subscription properly, so I was charged for something I will never used. Jumped on chat, which is usually awful, not a bot, a human, who liked my jokes. Refunded no quibble. If I ever need a pdf filler I will definitely sign up.

Nothing really. I have found it be very helpful.
Recommendations to others considering the product:
Easy to use and affordable.
What problems are you solving with the product? What benefits have you realized?
A nice looking final document with legible information as opposed to my illegible handwriting. No need for a typewriter to fill in blanks on forms which means more space for other equipment.

How do you calculate percentage resolution?
Resolution SLAB = The percentage of the number of tickets resolved within the SLA divided by the total number of tickets resolved during the selected time period within the filters.
How do you calculate voltage resolution?
As mentioned earlier, the resolution is the same as the smallest step size, and can be calculated by dividing the reference voltage by the number of possible conversion values. For the example we've been using so far, the resolution is 19.5mV.
How do you determine the resolution of a bit?
Resolution Calculation Method One method is R = 2n and the other is R = 2n 1, the former determines the number of discreet digital values and the latter the number of divisions between each discreet value. e.g. a 2 bit ADC would measure 4 separate values, whereas a 2 bit DAY would divide the output into 3 divisions.
What is the resolution of a 12 bit ADC?
ADC has a resolution of one part in 4,096, where 212 = 4,096. Thus, a 12-bit ADC with a maximum input of 10 VDC can resolve the measurement into 10 VDC/4096 = 0.00244 VDC = 2.44 MV.
What is 14bit resolution?
The 14-bit resolution is just the digital to analog conversion, 2^14 bits of information that is outputted. The Nigel_CreateWaveformFromFile16 is a form of data representation that consists of 16 bits waveform that you are 'creating' programmatically.
How do I choose ADC resolution?
Resolutions range from 8 to 18 bits and the sampling rate is typically in the tens and hundreds of USPS (kilo samples per second). Select devices approach 10 MAPS speed. An ADC with 8-bit resolution means that the digital code changes from 0 to 256 when the analog input voltage changes from 0 to full scale.
How is resolution calculated?
Another popular convention is to cite resolution as the total number of pixels in the image, typically given as number of megapixels, which can be calculated by multiplying pixel columns by pixel rows and dividing by one million. One could refer to it as 2048 by 1536 or a 3.1-megapixel image.
How is screen resolution calculated?
Screen resolution is measured by the number of pixels displayed in each dimension. For example if the screen size is 5.8 inches and screen resolution is 1138 × 680, then PPI can be calculated as 1138X 1138 + 680 × 680 = 1757444. Square root of 1757444 is 1325.69. Now, divide the number 5.8 i.e. 1325.69/5.8 = 228.5.
