How often do you need to convert audio files to alternative formats. Different MP3 players have different requirements. Some apps only work with certain formats, or maybe you need to compress the footage to fit in an email or upload it to a cloud service.
Whatever the reason, the web can help. There are dozens of audio file converters out there, each with different features and designed for different use cases.
And to find the top web-based audio conversion tools you can use for quick format conversions, we’ve rounded up free audio converters.
Zamzar is a multi-functional file conversion tool that has been around since 2006. It can convert audio files, text files, video files, and image files. In total, more than 1,200 different file formats are supported.
All common audio formats are offered, including 3GP, AAC, FLAC, IMY, M4A, MID, MP3, MP4, MXMF, OTA, XMF, RTTTL, RTX, and WAV.
It’s free to use Zamzar, but there are some limitations. The maximum file size you can upload is 150MB. However, you can still enjoy converting an unlimited number of files daily and can convert up to 25 audio files at the same time.
When you convert a file, Zamzar will store it on its own servers for 24 hours. If you don’t download it within that period, you’ll have to convert it again. For free users, the maximum amount of data you can store on Zamzar servers is 5GB.
If you need bigger uploads and more server space, you can sign up for one of Zamzar’s paid plans. Starting at $9 per month.
Online Audio Converter is ideal for people who work with music collections. As part of the conversion process, you can change the file’s metadata, including track name, artist, album title, year of release, and genre.
From your audio conversion needs, seven file formats are supported.
They are MP3, WAV, M4A, FLAC, OGG, MP2, and AMR. Online Audio Converter can also convert audio files into iPhone ringtones using the MPEG-4 format.
Several other features help the web application shine. For example, you can choose from four quality settings (64KBPS, 128KBPS, 192KBPS, and 320KBPS), set the sample rate, and decide whether you want the output file to be in mono or stereo.
There are also several on/off switches such as Fade in, Fade out, Fast mode, Mute, and reverse playback.
You can convert your local audio files, as well as files on Google Drive and Dropbox.
Aconvert is geared more towards people who need to edit their audio files. Audio conversion is available for 13 file formats.
Supported files are WAV, WMA, MP3, OGG, AAC, AU, FLAC, M4A, MKA, AIFF, OPUS, and RA), but there are also tools for trimming audio files and for merging audio files.
This app has a greater number of quality options than Online Audio Converter. Nine different KBPS settings are available, ranging from 32KBPS to 320KBPS. Uniquely, you can also enter your own custom KBPS settings just be aware that the higher the setting, the larger the file size.
Similarly, you can choose from four different sample rates. Again, you can choose custom settings if you wish.
Once the audio conversion is complete, you can download it to your desktop or use a QR code to save it to Google Drive or Dropbox. The maximum upload size for each file is 200MB.
Like Zamzar, FileZigZag is a versatile online file converter. Apart from audio files, you can also use this tool to convert documents, images, videos and even archive files like 7Z and ZIP.
You can use this tool to convert 29 different audio file formats, making FileZigZag one of the audio conversion web applications with the largest number of supported file types.
Supported formats are 3GA, ACC, AC3, AIF, AIFF, AIFC, AMR, AU, CAF, FLAC, M4A, M4R, M4P, MID, MIDI, MMF, MP2, MP3, MPGA, OGA, OGG, OMA, OPUS, QCP, RA, RAM, WAV, and WMA.
Unregistered users can convert files up to 100MB in size. If you sign up for a free account, the limit is increased to 180MB. For larger one-off files, FileZigZag sells 24-hour plans with a 2GB limit. Free users can only convert 10 audio files per day.
One of FileZigZag’s drawbacks is its dependence on email. When you convert a file, you cannot click the instant download informasi. Instead, you have to wait for it to arrive in your inbox. Sometimes, there is a slight delay.
The last online audio converter we recommend is Wondershare Online Uniconverter. This service is unique among the apps on our list; in addition to the free online tools, there are also accompanying free desktop applications for Windows and Mac.
However, in this article, we are only interested in web applications. It supports a large number of audio file formats.
The list includes WMA, MP3, WAV, RA, RM, RAM, FLAC, MP4, AU, AIF, AIFC, OGG, WV, 3GA, SHN, VQF, TTA, QCP, DTS, GSM, W64, ACT, OMA, ADX, CAF, SPX, VOC and RBS.
The service lacks some of the advanced tools we’ve seen in other web apps. For example, you cannot set the bit rate or sample rate. However, you can convert up to 25 files at the same time. If you have a lot of stash to settle, that’s a blessing.
In its literature, Wondershare claims its audio converter is 30 times faster than any other converter app on the web. We tested the app, and it sure was fast — but we can’t guarantee that the company’s “30 times” claim is accurate.
