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.

David SheltonIt’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.
Ana SuárezI use Zamar whenever I need to convert audio and video files from multiple submitters to 1 uniform file format for Audio and Video Editing. I can do multiple large files in a short amount of time.
Christopher BeeGreat 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 CalisGreat 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.
Jiunn-Ru LaiI feel like Zamzar is an active team member, especially for projects that I work on where I am the workhorse and it saves so much time and frustration. I am spoiled with Zamzar, because they have set the bar for file conversion and customer service very high.
Deborah HermanFantastic service! My mom's computer died and she has 1000+ Word Perfect files she wants to keep for some reason. Since Word Perfect is basically dead, I decided to convert all her files. Zamzar's converter was perfect.

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.

FLAC Audio Format FLAC Converter
An FLAC file has a full name of Free Lossless Audio Codec File and was developed by the Xiph.org foundation. An FLAC file is an open sourced audio file that uses lossless file compression which means that the file has been compressed to make it smaller but without impacting the quality of the file. i.e. it sounds the same but is smaller in size. In some circles it is known as a HD version of an MP3 file because it sounds a lot crisper than an MP3 but the way it has been built means that it tends to be a similar sized file as an MP3. It was developed in the early 2000s and given it’s size, quality and the fact it was open sourced it quickly became a popular alternative to other popular lossless audio formats which were developed at that time.
Another feature of an FLAC file is that it can support metadata and so they’re often used to burn CDs. Almost all open sourced audio players play FLAC files including the VLC Media Player. Other popular programs like QuickTime and Media Player do not play FLAC files.
