+# Output Format
+
+Configure the module format(s) for generated bundles.
+
+## Overview
+
+tsdown can generate bundles in multiple formats. Default is ESM.
+
+## Available Formats
+
+| Format | Description | Use Case |
+|--------|-------------|----------|
+| `esm` | ECMAScript Module (default) | Modern Node.js, browsers, Deno |
+| `cjs` | CommonJS | Legacy Node.js, require() |
+| `iife` | Immediately Invoked Function Expression | Browser `<script>` tags |
+| `umd` | Universal Module Definition | AMD, CommonJS, and globals |
+
+## Usage
+
+### CLI
+
+```bash
+# Single format
+tsdown --format esm
+
+# Multiple formats
+tsdown --format esm --format cjs
+
+# Or comma-separated
+tsdown --format esm,cjs
+```
+
+### Config File
+
+#### Single Format
+
+```ts
+export default defineConfig({
+  entry: ['src/index.ts'],
+  format: 'esm',
+})
+```
+
+#### Multiple Formats
+
+```ts
+export default defineConfig({
+  entry: ['src/index.ts'],
+  format: ['esm', 'cjs'],
+})
+```
+
+## Per-Format Configuration
+
+Override options for specific formats:
+
+```ts
+export default defineConfig({
+  entry: ['src/index.ts'],
+  format: {
+    esm: {
+      target: ['es2015'],
+    },
+    cjs: {
+      target: ['node20'],
+    },
+  },
+})
+```
+
+This allows different targets, platforms, or other settings per format.
+
+## Common Patterns
+
+### Modern Library (ESM + CJS)
+
+```ts
+export default defineConfig({
+  entry: ['src/index.ts'],
+  format: ['esm', 'cjs'],
+  dts: true,
+})
+```
+
+Output:
+- `dist/index.mjs` (ESM)
+- `dist/index.cjs` (CJS)
+- `dist/index.d.ts` (Types)
+
+### Browser Library (IIFE)
+
+```ts
+export default defineConfig({
+  entry: ['src/index.ts'],
+  format: ['iife'],
+  globalName: 'MyLib',
+  platform: 'browser',
+  minify: true,
+})
+```
+
+Output: `dist/index.global.js` (IIFE with global `MyLib`)
+
+### Universal Library (UMD)
+
+```ts
+export default defineConfig({
+  entry: ['src/index.ts'],
+  format: ['umd'],
+  globalName: 'MyLib',
+  platform: 'neutral',
+})
+```
+
+Works with AMD, CommonJS, and browser globals.
+
+### Node.js Package (CJS + ESM)
+
+```ts
+export default defineConfig({
+  entry: ['src/index.ts'],
+  format: ['esm', 'cjs'],
+  platform: 'node',
+  dts: true,
+  shims: true, // Add __dirname, __filename for CJS compat
+})
+```
+
+### Framework Component Library
+
+```ts
+export default defineConfig({
+  entry: ['src/index.tsx'],
+  format: ['esm', 'cjs'],
+  external: ['react', 'react-dom'], // Don't bundle dependencies
+  dts: true,
+})
+```
+
+## Format-Specific Outputs
+
+### File Extensions
+
+| Format | Extension |
+|--------|-----------|
+| ESM | `.mjs` or `.js` (with `"type": "module"`) |
+| CJS | `.cjs` or `.js` (without `"type": "module"`) |
+| IIFE | `.global.js` |
+| UMD | `.umd.js` |
+
+### Customize Extensions
+
+Use `outExtensions` to override:
+
+```ts
+export default defineConfig({
+  entry: ['src/index.ts'],
+  format: ['esm', 'cjs'],
+  outExtensions: ({ format }) => ({
+    js: format === 'esm' ? '.js' : '.cjs',
+  }),
+})
+```
+
+## Tips
+
+1. **Use ESM + CJS** for maximum compatibility
+2. **Use IIFE** for browser-only libraries
+3. **Use UMD** for universal compatibility (less common now)
+4. **Externalize dependencies** to avoid bundling framework code
+5. **Add shims** for CJS compatibility when using Node.js APIs
+6. **Set globalName** for IIFE/UMD formats
