Volcano Plot Maker

Paste a differential-expression table (DESeq2 / edgeR / limma / Seurat, …) and get a publication-ready volcano plot as SVG or PNG.

Everything runs locally in your browser. Pasted data is never uploaded to any server.

Paste your data, or click "Load example" to see how it looks.

Matches the volcano plot on the platform: square canvas, 6 pt body text, Arial, same colors, threshold lines, legend (counts in class names) and gene label leader lines; width 61 / 89 / 183 mm.
Significant = p below the cutoff and |log2FC| above the cutoff (both strict, as on the platform). Labels go to the top N significant genes by p-value.
Prefer adjusted p-values (padj / FDR); raw p-values can be chosen if that is all you have.
