123APPS offers various tools for video, audio, and documentary files. Online Audio Converter is one of the services used for converting video/audio files to MP3, WAV, M4A, OGG, and more. Free users are allowed to process 70 files per day, which is more than enough for basic use. Moreover, there is no sign-up required. It’s accessible for everyone. Simply upload your MP4 video from your local drive, Google Drive, Dropbox, or from an URL link, select MP3 and then hit Convert. You are also provided with customization options of audio bitrate, sample rate, and channel. Only paid users can convert a unlimited number of videos per day.
Similar to 123APPS, Converter App is also a collection of free file converters. Not only can you convert video and audio files, but you also can convert PDFs and images. The usage of these converters is 100% free, no hidden charges, no sign-up required. Moreover, this free service tries not to limit the number of files users can submit or the file sizes. With Converter App, you can convert MP4 to MP3 online for free, and as many times as you want. The only drawback is that uploading large files takes much time. It also supports conversions between AVI to MP4, MP3 to WAV, and MP4 to WAV.
In simple clicks, you can convert WAV, M4A, MP4, MOV, MKV and more files to MP3 with Restream. This easy-to-use online converter enables you to upload a file of up to 1GB file size and has no limits on how many files you can convert. More importantly, there is no need to create an account. It will delete your files from its servers a few hours after you’ve downloaded them, so nobody has access to them.
These 5 online video converters are convenient solutions, especially if you need to convert an MP4 file to MP3 quickly.
