At times, it is difficult to edit the pdf the way you want. There are too many steps to take in order to do what you want with your document. Eventually, I am able to get the pdf the way I want it.

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!

For pdfFiller’s FAQs

Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.
Multiply PPI × PPI to get pixels per square inch. The number of pixels in a square inch represents the resolution or pixel density of an area of one square inch. Substitute 1 cm for 1 inch to find pixels per square centimeter or PPcm2.
Resolution (r) = 1.22/(NA(obj) + NA(cold)) Where r is resolution (the smallest resolvable distance between two objects), NA is a general term for the microscope numerical aperture, is the imaging wavelength, NA(obj) equals the objective numerical aperture, and NA(cold) is the condenser numerical aperture.
Equation (1) indicates that the resolution is the difference between peak retention times divided by the average peak width. In a peak with Gaussian distribution, the peak width is W = 4 (where is the standard deviation) and the peak FHM is W0.5h = 2.354.

The resolution of an elation is a quantitative measure of how well two elation peaks can be differentiated in a chromatographic separation. It is defined as the difference in retention times between the two peaks, divided by the combined widths of the elation peaks.
A resolution value of 1.5 or greater between two peaks will ensure that the sample components are well (baseline) separated to a degree at which the area or height of each peak may be accurately measured. Calculation of Chromatographic Resolution (RS)
Column efficiency calculation Column efficiency, indicated as the number of theoretical plates per column, is calculated as N = 5.54 (tR / w0.5)2 where tRy is the retention time of the analyte of interest and w0.5 the width of the peak at half height.

You can take either the horizontal or vertical resolution. Once you have the resolution, you must measure the length of the display. Usually, this will be measured in inches (2.54 cm = 1 inch). If you divide the two numbers, you'll find the pixels per inch (PPI).
Once you have these two pieces of information (the print size and the pixel count), you can calculate the PPI and determine the resolution of the image. Calculating PPI The basic equation for calculating PPI is: PPI = width(pixels)/ width of image (inches); PPI = height(pixels)/ height of image (inches).
