LaTeX packages on Overleaf

Overleaf provides all the LaTeX packages that come with a standard LaTeX installation.

Overleaf uses TeX Live for new projects and copies of existing projects, which provides about 4000 packages, including:

• Figures with pstricks and TikZ. Here are some examples.
• Bibliographies with bibtex and biblatex. Here are some examples.
• Packages, such as fontspec that require XeLaTeX or LuaLaTeX for unicode and font support.

If a document class or package that you wish to use is not available in your project's version of TeX Live, in many cases you can upload the required .sty and .cls directly to your project.
