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.

Used 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!

I'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.

I 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.

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.

I 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 Bee

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.

I 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.

Fantastic 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.

EPUB eBook Format

EPUB Converter

EPUB is the standard open-source format for ebooks. EPUB is short for ‘electronic publication’. The format was developed in the mid-late 2000s by the International Digital Publishing Forum and is an alternative to formats like AZW, developed for the Kindle. EPUB files can be viewed on a wide range of e-readers and digital reading apps, including NOOK, Apple Books, Okular and Calibre. Amazon announced in 2022 that new Kindle models would also support EPUB files.

The EPUB standard is now maintained by a World Wide Web Consortium (W3C) working group. The EPUB format comprises three open standards – one defining content markup, one describing the ebook structure, and one packaging all the files into a compressed format. EPUB files normally include an index page for navigation, and accessibility features to adjust text size or allow for text-to-speech. EPUB also has the potential to include interactivity, accessible image, video, or audio elements.

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.
