3GP files are a legacy video format originally designed for use with early mobile and internet devices. The format is capable of storing video and audio data in a highly compressed format. This naturally led to a decrease in quality but was heavily driven by the need to minimize file size, thus reducing the bandwidth usage of the early devices.
The video audio and video compression were highly effective and allowed video clips created on these devices to be shared without consuming large amounts of bandwidth. The low-resolution camera and displays of these early mobile devices also helped keep file sizes to a minimum.
The 3GP format is still fairly common today; however, it is in decline and has mostly been replaced by other video formats, such as MP4. We have a selection of M4A converter tools for converting these files into other formats if native video editing applications lack such features.

PNG files are a widely used graphics file format used in areas where high-quality images (often with transparency) are required while also retaining a small file size. They are one of the most common formats of file used for web and print mediums and are particularly useful for logos, icons, and other images where multi-level transparency is desired.
The format itself was created in the 1990's with the main aim of storing computer graphics in a high-quality format while minimizing the required storage space. The longer-term aim was to displace the GIF file format and make PNG the number one format for non-lossy, high-quality image formats on the then-burgeoning world wide web.
One of the selling points of the PNG format is its support for multiple levels of transparency, making it superior to the GIF format, which can only handle a single level of transparency. Also, like GIFs, the PNG format supports palletizing image colours down to 256 or 16 colours to help reduce the file size of the PNG.
