WinMP3Packer is an application that can help you free up space by reducing the size of your MP3 files without sacrificing quality.
This kind of tool is ideal when you want to store several audio tracks on an external device, such as an MP3 player, but don't have enough space at your disposal.
The interface of the program consists of a standard window in which you can import files or a folder by using the file browser or the "drag and drop" method (batch processing is also supported).
Audio configuration settings
So, you can process files with constant or variable bit rate (or all of them, regardless of the bit rate). Furthermore, you can select the compression algorithm (VBR or CBR), set the minimum bit rate, strip non-MP3 data (at the start or end of file) and append text to file names.
You can enable alternate broken frame behavior, to super-squeeze files and to overwrite existing ones. In addition, you can save and load settings in profiles, select the output destination (same as input or other, optionally recreate subfolders and copy unprocessed MP3s) and input command lines.
Results and performance
Once the task has been completed, a window pops up in which you can find out how much size has been reduced in the respective MP3 files.
The program uses a low-to-moderate amount of system resources and quickly finishes a job without popping up any errors. Everything ran flawlessly during our tests.
Performance and final thought
We selected the maximum value for the minimum bitrate (with the VBR output type), and WinMP3Packer managed to reduce the size of an MP3 file by 58.3% percent. The difference in the sound quality is slightly noticeable. Unfortunately, there is no help file available and this can be inconvenient to novices. Otherwise, we strongly recommend WinMP3Packer to all users.
