The PNG (Portable Network Graphics) file format was designed in the mid-1990s as an improved alternative to the previously existing JPG and GIF formats, and as an extension which would be particularly web-friendly. In time, PNG files have gained a wide popularity and are highly appreciated at the moment for their ability to provide a lossless compression of images, which translates in high-quality and detailed renderings.
CGM (Computer Graphics Metafile) is a format that contains vector graphics information (clip art, drawings) associated with graphics design or CAD programs. As opposed to other types of metafiles, such as EMF or WMF, CGM files are not only supported by Windows, but can be used on different platforms too. They are encoded using binary, character-based of clear-text encoding.
The quick and simple way to handle your files is to get a quality piece of software, such as reaConverter. Although it is fast, this software is extremely efficient in managing a wide range of conversions. As you will soon realize, reaConverter will help you avoid spending countless hours trying to figure out how to convert PNGs. But at the same time, it will allow you to apply a wide range of editing options.
Start reaConverter and load all the .png files you intend to convert into .cgm because, as opposed to most free online converters, reaConverter supports batch conversion. So you can save the time and energy you would lose with doing repetitive operations.
Select PNGs from a folder or by drag-and-dropping them directly into the reaConverter window.
Go to the Saving options tab and decide where you want to save new .cgm files. You can also spend a few more moments to apply additional editing to the images prepared for conversion.
Then pick the CGM as output format. To help you do this, a series of buttons is conveniently placed at the bottom of the reaConverter window, so you can simply press on the one you need or click Plus button to add new options.
Then simply press the Start button and your conversion will begin in no time!Try Free Trial Version
