Pazera Free WMA to MP3 Converter is a program that converts Windows Media files (WMA, WMV, ASF) to MP3 or WAV format. Additionally, the program allows you to copy (extract) original audio tracks from supported files without loss of sound quality. Moreover, the program also allows you to split audiobooks into MP3 files based on chapters stored in the source files.

Converting files / extracting audio tracks

To convert WMA, WMV and ASF files or extract audio tracks from these files, you must first add them to the list. To do this, click the Add files button on the toolbar. Will be displayed a standard dialog box for file selection, in which you have to select one or more audio or video files, and click Open button. You can also add files to the list using the drag and drop technique. When you do this, the program will add your selected files to the processing list. To run the conversion/extraction, on the list must be at least one file, moreover, it must be checked in the column with check boxes.

If you ran the program for the first time and have not changed any conversion parameters, will be used default settings.

At default settings, the application converts files to MP3 with constant bitrate (CBR) and automatically selects all the encoding parameters so as to preserve the original audio quality.

You can manually set the encoding parameters on the Audio and Additional settings panels, or just select one of the predefined profiles from the Profile list.

If you want to extract the original audio track from the video file without loss of sound quality, select Try extract original audio stream on the Output format list.
The program can extract the audio tracks encoded in the following formats: WMA, MP3, AAC, M4A, OGG (Vorbis), AC-3, PCM (WAV), AMR.

The most important audio conversion parameter is audio bitrate. Generally, the higher bitrate, the better sound quality in the output file. But on the other hand, the higher bitrate, the larger output file. The whole trick is to select those bitrate value to get good sound quality at a relatively small size of the resulting file. So it is best to set the audio bitrate in Auto position, then the program will select the appropriate value automatically. However, if you want to manually set conversion parameters, you can find a lot of useful information in the File properties window (select desired file on the list and click the File info button on the toolbar).

If you want to reset all conversion settings to default values, select menu Encoder -> Default encoder settings.

When you set all conversion/extraction parameters, click the Convert button on the toolbar. A new window appears, where you can track the conversion process.

Splitting files based on chapters


If the input file contains a menu with chapters, the program will automatically split the file by that chapters. Each chapter will then be listed in a separate row (see picture above). After the conversion, each chapter will be saved to a separate file.
If you do not want to split files based on the chapters, you can disable this feature in the application options: click Options button on the toolbar and uncheck Split files by chapters.

Metadata (tags)

By default, all metadata are copied from the source files to output files, but he program also lets you add custom metadata (artist, album, title, year, comment etc.). If you want, you can also completely disable writing metadata to output files.

Managing file list

You can activate/deactivate any files in the list by checking/unchecking desired files in the 2-nd column (with the check boxes). Only the checked files will be processed during conversion.

If you want to remove from the list some files, check them in the 2-nd column and click Remove button on the toolbar. All checked files will be removed from the list (but not from disk!). If you want to remove from the list all files, select menu File list -> Clear file list.

You can change the location of files on the list using the drag and drop technique. Similarly, you can move the list columns.

If you want to show or hide some column, right-click on the file list header, and in the context menu, select or deselect the desired column.

You can sort (ascending or descending) the displayed information by clicking the appropriate column header.

Loading & saving settings

When you close the program, all conversion settings are saved to the file __Last.ini in the profiles directory. The next time you run application, conversion settings are loaded from this file.

The rest of the application settings (main window size and location, columns order and visibility, and others) are stored in the file WmaToMp3.ini in the program main directory. Of course, these settings are also loaded at the next startup.


The program does not use system registry and all settings are stored in the above-mentioned files. If you want, you can copy all files (including whole directory structure) to the USB drive, and run the program from that drive on other computers.
You can also download the program in the form of a ZIP archive and extract it to an external drive.
