Theorem is a free online tool that converts LaTeX to PNG, SVG, WebP, JPG and vector-PDF images. Type or paste LaTeX, watch it render live, then export equations with transparent backgrounds, custom ink colors, padding and corner radius. Supports LaTeX environments (equation, align, cases, matrices, arrays), inline autocomplete, 40+ formula templates and a full command reference — all client-side, no signup.
Type LaTeX, watch it typeset live, and press it out as a crisp image — a transparent PNG, a true-vector SVG or PDF — ready for slides, papers and notes.

Everything runs locally; only MathJax, the fonts and — on PDF export — jsPDF load from a CDN. Your input and settings stay in this browser's localStorage. JPEG has no alpha channel, so transparent backgrounds are filled white. PDFs are true vector when svg2pdf is available, otherwise rasterized at export scale.
