TXT is a document format: it contains raw Unicode or ASCII characters with no embedded formatting, fonts, or layout information. PPM is a document format that stores data in the PPM 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. Converting between these two formats is common when the source application does not support PPM natively or when the target platform only accepts PPM. 1converter processes this conversion server-side using open-source tools. Files are transferred over HTTPS, converted on secure cloud servers, and automatically deleted after 24 hours.
