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The 3GP format is still fairly common today; however, it is in decline and has mostly been replaced by other video formats, such as MP4.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.

The AVIF file format is aimed at being a modern replacement for the popular JPEG image format. Developed by the Alliance for Open Media, AVIF is an advanced image file format that leverages the cutting-edge compression algorithms used by the AV1 video codec.
The aim of the format is to surpass the quality of the equivalent JPEG file while packing a smaller file size via the use of the AV1 compression algorithm. The aim of the compression algorithm, which is a lossy algorithm, is to reduce the file size by removing detail from the image that the eye would not normally notice, thus reducing the size of the final AVIF file.
Support for AVIF files is still growing, with many modern image editors able to read and write to the format. The latest versions of the most popular web browsers have also moved to support AVIF images, having seen the benefit to website developers of reduced image sizes and thus reduced bandwidth usage.
