Zamzar has converted files since 2006, always the same way: your file is uploaded, converted on their servers, and downloaded back. Filemorph converts on the device itself, so there is no upload, no 50 MB cap and no two-a-day limit.
Zamzar's no-cost service is deliberately small: 50 MB per file, two conversions and two compressions in any 24 hours, and the converted file waits on their servers for a day. Their desktop app for Windows and Mac uploads too; their FAQ says it needs an internet connection.
Filemorph is the opposite shape. It is an app, not a website, and it only runs on iPhone, iPad and Mac. In exchange, the file never leaves the device, nothing is counted per day, and the only size limit is your storage. If you convert one file a month and never on a phone, Zamzar's no-cost tier may be enough. If you convert often, or the file is private, keep reading.
