MP4 to MP3 Video Converter Pro Online Tutorial

How to Convert MP4 to MP3?

MP4 to MP3 Video Converter Pro can easily convert multiple MP4 files to MP3 all at once. Just select the MP4 files as sources and set MP3 as the output format (by default, the app uses MP3 as the output format), then follow the steps below to complete the converting.

3 Steps to Convert Video/Audio Files to other format

• Add source multimedia files to the tool
• Check and config output folder, output format and advanced options if necessary
• Start converting

Step 1 – Add Multiple Files to Convert

There are two ways to add files to the conversion tool.

Method 1, click the button “Add File” in the toolbar, select the files that you want to convert, and then click the button “Open”.

Method 2, if all your files to be converted are in the same folder, you can use the button “Add Folder” to add all of them all at once, instead of selecting each one of them. Click the button “Add Folder” in the toolbar, select the folder containing your multimedia files, and then click the button “OK”.

How to Remove Files?

You can select and remove files one by one. You can also remove all the files in the list.

To remove a file from the list, you need to select it by clicking it and then click the button “Remove File” in the toolbar.

To remove all files from the list, you need to click the button “Clear” in the toolbar.

Step 2 – Check and Config Output Folder, Output Format and Advanced Options if Necessary

First, check and make sure you are OK with the output directory setting. By default, with the “Save in the same input file directory” option checked, the output file will be saved in the same folder as the input file. If the input files are from different folders, the output files will be in different folders. On the other hand, you can always uncheck that option, and select a “real” Output Directory by clicking the folder icon to the input box above. This way, all the output files will be located at that folder.

Second, check and make sure you select the correct output format. The default output format is MP3, but you can always change it by selecting a new one from the drop-down list.

Third, optionally, you can config advanced options for the output format. Click the link “Advanced Options” and the options window will appear. For video formats, you can change Size, Fps, and Bitrate. For audio formats, you can change Frequency and Bitrate.

Step 3 – Start Converting

When you have inserted all your source files, you can start the batch conversion by clicking the button “Convert”. The files in the list will be processed one by one from top to bottom.

Note:  the status of “Ready” in the file list means that file is ready for conversion and you still need to click the button “Convert” to start the converting process. The status will become “Complete” once that file is successfully processed.

Where Can I Find the Output File?

Once the conversion process is done, you can go to the output folder to find the converted files. The converted file’s name is the original file name followed by “_Converted”. If there is a file with the same name in the same folder, the app will append a “(X)” to the name, in which X is a number. For example, blabla_Converted.mp3, blalba_Converted(1).mp4 etc.

If you want to convert some other files, you need to either remove the converted files one by one from the list by using the button “Remove File”, or more efficiently, you can just close the app and re-start it with a empty file list. Then you can follow the steps above and convert again.

What to Do if the Conversion Failed?

If one file fails to convert in the app, we kindly ask you to follow the instructions below.

First, please close other apps in your PC if there are any, to give this app enough RAM to process the conversion.  Try to convert that specific file again.

Second, if the re-try still fails, please send an email to us with that file sample. We will try our best to help you.
