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.
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.

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.

PPSX Document Format PPSX Converter
PPSX is a PowerPoint Open XML Slide Show - it is primarily designed to be non-editable and to simply playback the Powerpoint presentation. It differs from PPTX which allows for the file to be editable. The 'X' extension refers to Microsoft Office 2007, 2010 and 2012 which ZIP compress the file and is therefore different from the previous versions which were generally have larger file sizes.

PPTX is a PowerPoint file type developed by Microsoft as part of Office 2007. PPTX was developed by Microsoft in order to allow information to be more readily shared between different programs and to also help reduce the increasing file sizes that had come in previous versions of Office.
PPTX files have the same functionality as PPT files in that there are various templates that can be used and the presentations can include different multimedia, text and can contain animation and a range of different transitions. PPTX replaced PPT as the standard for Microsoft PowerPoint files and the big difference between the two PPTX file data is stored in the Open XML format which stores data as seperate files and is zipped to reduce space.
This is compared to the PPT file type which stores the data in a single binary file. PPTX files can be opened by various programs including OpenOffice programs, Apple KeyNote and Preview and on the web with applications like Google Drive.
