Different programs store the same kind of information in different formats, the format is indicated by the extension to the file name, which is usually 3 characters. For e.g. a text file may be stored in a .docx or a .odt or a .txt format, a music file may be in a .wav or a .mp3 or a .ogg format. Some formats are ‘open’ while others are ‘closed’. An open format is a file format for storing digital data, defined by a published specification usually maintained by a standards organization, and which can be used and implemented by anyone (see <nowiki/>https://en.Wikipedia.org/wiki/Open_format), whereas a non-open or closed format may not be possible to be implemented by anyone other than the vendor. Open formats should be preferred for OER, since they share the underlying rationale of being used/usable by anyone. You may want to convert your file from a closed format to an open format.

Another pragmatic reason, you may have a need to convert a file from one format to another. A video that plays on your computer may not play on your DVD player, or a music clip that plays on your computer may not play on your mobile phone.

The formats that LibreOffice saves files conform to the ‘Open Document Format’ for text (.odt or open document text), spreadsheet (.ods or open document spreadsheet), and presentation (.odp or open document presentation). You can convert a document which is in another format into these formats by simply opening the document in LibreOffice and then using <u>File → Save As</u> to save in these open formats.
