I tried it and immediately fell in love! It was so easy to use! After a couple conversions I bought the guys a cup of coffee. A couple more and decided this was too good to abuse! I joined! My life is so much easier!

I had a huge, problematic file to convert that couldn't go through the usual automated conversion process. The Zamzar team responded quickly to my request for help, and they took the extra steps needed to do it manually.

It’s my first time using it. I had some complications doing it. I’m not very good at this. But I wrote to the company and I had a lot of help. I’m satisfied with customer service and with the app.

Great for when you need a lot of conversions in a short time. You have directly access and can even put the subscription on for just a month.

Sabina Calis

Great thanks to you all for helping me to get the OLD files converted correctly. 20 years, quite a long time, reviewing the files brings much memory to me. That's the best gift I received last year. Thank you all again.

MP3 Audio Format

MP3 Converter

MP3 goes by the full name of MPEG Audio Layer-3 and is perhaps the most widely used audio file around today. MP3 is a file format developed by the Moving Pictures Expert Group (MPEG) which uses compression to produce smaller file sizes. The type of compression used means some data is lost, but typically audio playback quality is not obviously impacted, especially when recording files at higher bitrates. Other popular audio formats, such as WAV, can be up to 10 times the size of an equivalent MP3 file. Almost all applications are able to open MP3 files including Windows Media Player and iTunes on macOS. The MP3 file format famously exploded in popularity during the '90s and '00s as music moved online and become digitised.

WAV Audio Format

WAV Converter

A WAV file also goes by the name of a WAVE or Waveform audio file. The WAV file is one of the oldest types of audio file in existence today and was developed by Microsoft and IBM. Despite being developed in 1991, it is still a popular file format today.

Part of the appeal of WAV files is that they’re exceptionally high quality because they are uncompressed and lossless. WAV uses PCM (Pulse Code Modulation) to encode the audio data by segmenting it into small pieces, and does so without any compression; this means the process doesn’t impact the audio quality in any way.

WAV files are used by musicians to record music, with this format providing a much richer sound than other compressed file formats. Unsurprisingly, WAV files tend to be large in size because they’ve not been compressed in any way - they are typically over ten times the size of an MP3 file.

WAV files can be opened by almost all audio programs, mainly because they’ve been around for over thirty years and because they’re so widely respected.
