You can't just import the PDF. VTT character sheets (R20, Foundry, etc) are essentially nested web pages built with html, css, and javascript. You can build a custom sheet to use in your own games or to submit to the Roll20 repository. There are two sheet structures you can build in: Legacy Sheet : Raw html/css/js. Can be used as a custom sheet in your game without sharing with the community Beacon sheet : Uses modern web development framework of your choice. Can only be used by uploading to the R20 beacon sheet repository and having intent to release it to the community. If you are not inclined to code, I recently launched the alpha version of Sheet Architect ( Forum Announcement ) which provides a GUI for building R20 compatible sheets.
