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!
TillieI 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.
PDinSFUsed it for over a year to convert my bank statements to csv files. Great quick app, increased my productivity a lot. Also, amazing support - always helped me quickly!
Agata WierzbickaI 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.
MaryA very useful and professional site. The service is easy to use and the administrators are helpful and courteous.
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 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
The MOBI ebook format was developed by the French company Mobipocket in 2000. MOBI files were intended to be used on mobile phones, computers and personal digital assistants (PDAs), which were popular in the 1990s and early 2000s before the arrival of smartphones. Unlike EPUB files, MOBI files were protected by Digital Rights Management, making it harder for the contents to be copied and shared.
Amazon bought Mobipocket in 2005. The company retired the MOBI format and support for it in 2016 after developing the AZW and AZW3 formats for the Kindle. However, you can still read MOBI files on Kindle devices and with the Calibre ebook application. You can also get specific MOBI-reader software. If you use an ereader that doesn’t recognise MOBI files, you may need to use a tool like Zamzar to convert them into another format like EPUB.

AZW3 eBook Format AZW3 Converter
An AZW3 file format is also known as an Amazon KF8 e-Book file and was developed by Amazon to replace the older AZW file. AZW3 files are similar to AZW files in that they’ve been designed for the Kindle so that they support formatting, chapter markers and so on. Just like the AZW file they also have DRM protection built in meaning they can only be opened by Kindle devices – i.e. devices that are authorised to open these files. This DRM protection is Amazon’s way of trying to prevent piracy occurring and books being shared without people paying for them. The key difference between AZW3 and AZW is around AZW3’s ability to support HTML5 and CSS3 which means that these files are a lot more advanced when it comes to formatting including being able to support illustrations. As more and more new generation Kindles get sold the AZW3 format is becoming increasingly popular. To open an AZW3 file a user must have a Kindle or use a program called Calibre.
