The PEF file format stores data in the PEF format. Converting to ODT produces a document file that stores text and formatting as a zipped ODF XML archive, the ISO-standardised open alternative to DOCX. 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. This makes ODT the practical choice when the destination system requires it or when the target format offers better compatibility or compression. 1converter runs this conversion on the server: your file is uploaded encrypted over HTTPS, converted using trusted open-source libraries, and the output is held for 24 hours before automatic deletion.
