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'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.
JHA 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.

CHM eBook Format CHM Converter
A CHM file has a full name of a Compiled HTML Help File and typically contains documentation in the form of a compressed HTML file. The type of documentation is typically help documentation that includes text, hyperlinks and even images. The file allows users to search and it can include tags making it an ideal format for a help manual. It was popular in the early days of the Web as they were fully compatible with early browsers. Their popularity started to wane after vulnerabilities surrounding the files were targeted leading to high profile hacking incidents. Help documentation has improved in the twenty years since CHM was popular leading to the file becoming used increasingly infrequently. Almost all modern web browsers still support the file although recommend caution when using it.

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.
