# PDF Standards

PDFs can be used for various purposes, such as web display, printing, or archiving. Over time, different standards have been developed for these use-cases. Typeset.sh enables you to save your PDF as different standards by properly tagging it. However, it is your responsibility to ensure that the PDF does not include any features that are not allowed for the chosen standard.
