ET file (ET) stores data in the ET format. DDS file (DDS) stores data in the DDS format. This conversion changes the file's encoding, compression method, and supported feature set. Text content, headings, and basic formatting are transferred; complex features such as macros or embedded objects may not translate fully. The result is a standard DDS file readable by any compatible application. 1converter handles ET-to-DDS conversion server-side: files are uploaded over HTTPS, processed on isolated cloud infrastructure, and the converted output is available for download for 24 hours before automatic deletion. No account is required for standard conversions.
