This application allows you to produce various image files from PDF file, e.g., JPG, PNG, TIFF, BMP, TGA, PCX, etc. on Windows platforms. And also it is a standalone software which does not depend on other software, e.g., PDF editor or reader, etc.. With the help of this application, produced image files could be anti-aliased correctly and professionally, including font anti-aliasing, vector anti-aliasing and image anti-aliasing, etc.. So if you want to use this software to convert PDF file to image file with anti-aliasing, please follow steps below to accomplish it in your Windows systems.
Step1. Download this utility
To use this utility, please firstly download its pack with following icon, then extract its content to your computer, and then, e-PDF to Image Converter could be used by you later in limited times.

pdf2img.exe -aa no –aaimg yes C:\in\source1.pdf C:\out\target1.png
In the example above, pdf2img.exe is to call executive file pdf2img.exe in order to use related application, –aa no is to disable font anti-aliasing during converting PDF file to image file, also you can use –aa no, which is to help you anti-alias font during conversion directly, –aaimg yes is to anti-alias image during converting PDF file to image file automatically, and you also do not need to type this parameter for default setting is to help you anti-alias image directly same like other anti-aliasing.

Extension Knowledge:
In computer graphics, anti-aliasing is a software technique for diminishing jaggies - stairstep-like lines that should be smooth. Jaggies occur because the output device, the monitor or printer, doesn't have a high enough resolution to represent a smooth line. Antialiasing reduces the prominence of jaggies by surrounding the stairsteps with intermediate shades of gray (for gray-scaling devices) or color (for color devices). Although this reduces the jagged appearance of the lines, it also makes them fuzzier. Another method for reducing jaggies is called smoothing, in which the printer changes the size and horizontal alignment of dots to make curves smoother. Anti-aliasing is sometimes called oversampling.
