LaTeX Theme Editor

A free, browser-based tool for designing the visual style of LaTeX documents without hand-editing the preamble. Pick fonts, colours, heading sizes, page margins, and header/footer layout — then export a ready-to-use preamble in one click. Everything runs in your browser; nothing is sent to a server. This is a limited-time free-trial provided for personal-use.

How to use it

Pick a preset from the dropdown at the top of the left panel to start from a curated theme.
Expand a panel — Typography, Headings, Page Layout, Colours, or Header & Footer — and adjust the settings.
Watch the preview update in real time on the right.
Export your theme: click Export to copy the preamble to your clipboard or download it as a .sty file. Then paste it into your .tex file or place the .sty file next to it and add \usepackage{mytheme}.
Share your theme: the Share button copies a URL that encodes your entire configuration. Send it to a collaborator — no account needed.
