Users can type in a URL or upload one or more files (if they are all of the same format) from their computer; Zamzar will then convert the file(s) to another user-specified format, such as an Adobe PDF file to a Microsoft Word document.[7] Once conversion is complete, users can immediately download the file from their web browser.[8] Users can also choose to receive an email with a link to download the converted file.

File conversion APIEdit

in 2015 Zamzar launched a file conversion API, allowing users to integrate file conversion capabilities into their own websites and applications.[9] Sample code is provided to allow users to integrate file conversion capabilities in C#, Java, Node.js, PHP, Python and cURL[10]. Zamzar also maintains a project on GitHub which allows users to perform file conversion from the command line on Linux, MacOS or Windows systems.[11]

Email file conversionEdit

It is also possible to send files for conversion by emailing them to Zamzar.[12] Zamzar launched this capability in 2012,[13] allowing users to email files to dedicated email addresses for the file to be automatically converted to a different format. A link is then emailed back to the end user to allow them to download their converted file. For example, to convert a .doc attachment to .pdf users would simply email the file to


Zamzar does not publish lists of customers that use their services, but in 2019 they announced[14] that Xerox Corporation would be using the Zamzar API to help power conversions in the Xerox Audio Document application.

User privilege levelsEdit

Zamzar is currently free to use, but there is a limit of two conversions per day. Users can pay a monthly subscription in order to access preferential features, such as unlimited file conversions, online file management, shorter response and queuing times and other benefits.[15]

Naming etymologyEdit

Its name comes from Franz Kafka's The Metamorphosis. Its main character is called Gregor Samsa and it is from his surname that Zamzar is derived.[2][16] The founders of the service considered three other names – Konvertieren, Khamailen and Obrogo – before settling on Zamzar.[17]
