The application to reduce video size without losing its quality is an application that aims to reduce the size of video files so that the file size is reduced without significantly affecting the video quality. This type of application is useful when you have large video files and need to free up storage space on your device or when you need to share video online quickly or reduce internet data consumption.

These applications work by applying advanced video compression techniques, such as lossy compression techniques. Compression tools are used to analyze video data, remove unnecessary data, or reduce video resolution in areas of the image that do not significantly affect the viewing experience. The most important parts of the image and their high detail are kept remarkably clear.

Some applications also provide custom settings for users to adjust the video quality level and output size according to their own needs. These applications can have a user-friendly interface that allows users to upload the desired video and choose the appropriate settings after which the size reduction process is applied with the push of a button.

It should be noted that although these applications limit the final file size, reducing the size may result in a slight loss of quality in some cases. However, the effect of loss is usually not noticeable and can be accepted in most cases.

It is a good idea to choose a trustworthy and reliable application to achieve the best results and avoid unwanted loss of quality. There are many apps available on different operating systems, such as Android, iOS, and Windows, and they can usually be found in official app stores.
