How to Convert PNG Images to PDF Documents

These days users have a wide range of modern tools that provide many new options when handling files.

Users may also choose to work with many different formats of documents and media files. But making these different types of files to combine and effectively function isn't always an easy task. An example of this might be if you need to convert an image to a portable document format.

The most well-known and widely-used image formats for most of us are JPG (or JPEG - from Joined Photographic Expert Group) and PNG (Portable Network Graphic). Many people prefer the latter one because it’s aimed at lossless compression - which means that the file retains the quality of the image no matter how many times you re-save or manipulate it.

File extension .png
Internet media type image/png
Description: Today PNG (Portable Network Graphics) is one of the most popular raster formats in web graphics. In 1995, at one of the Usenet conferences, they proposed to develop an alternative to the popular GIF format. The main purpose was to create a new format more flexible and free from patents. This is how PNG appeared, which is unofficially decoded as “PNG IS NOT A GIF”.
Technical Details: A PNG file offers a higher quality level than a GIF file. PNG files support both the 24-bit RGB and 32-bit RGBA color profiles but do not support the CMYK profile, simply because they weren’t designed for printing. The reason you would choose this format over GIF is that PNGs don't have copyright limitations and lets you work with a wider range of colors.
