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!

Agata WierzbickaI've used this product for years. And customer service is excellent. Just had an issue where I was charged and I didn't agree with the charge and they took care of it, even though they didn't have to.
JHI have been so thankful for Zamzar’s support from the beginning of the Pandemic to the present day. Their service is first rate & their helpfulness is always the best it could be.

David SheltonI 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.

MOBI eBook Format MOBI Converter
A MOBI file has a full name of Mobipocket e-book and is an e-book file format that has been developed by Amazon and are the basis of the file formats used by all Amazon Kindle devices. A MOBI file differs from the other popular e-book format, epub, in that it is protected by Digital Rights Management which essentially pins the book down to just the one device so it can’t be used if not registered to the users account.
MOBI file formats have provided the basis of the recently created KF8 file format which are used in the most recent Kindle formats. As e-books and e-readers become more popular, the MOBI format’s use has largely fallen away but it is still the base on which many of the more modern e-book formats are based including AZW and AZW1.
Programs that can open a MOBI file format include the Kindle and and the tool Calibre.

EPUB eBook Format EPUB Converter
An EPUB file, which is a shortened form of "electronic publication", is an open e-Book file format. It is widely considered the most popular file format for digital books as it works on almost any e-reader.
EPUB was developed by IDPF and is considered the standard format in digital publication. It is based on three open standards - one that determines the content markup, another that describes the structure and finally a container format that compresses all the files into one format. All three standards are maintained by the IDPF. It's possible to open an EPUB file using programs such as Apple Books or Adobe Digital Editions, but it's to view an EPUB file on Amazon's Kindle reader, you would firsy need to convert the file to a supported format (such as MOBI).
To edit an EPUB file it's possible to use specialised e-Book editing software such as Calibre.
