+# Minimum Length Text Validator
+
+Register a validator that filters out extraction results with text below a minimum length threshold.
+
+```typescript title="WASM"
+import init, { registerValidator, extractBytes } from "kreuzberg-wasm";
+
+await init();
+
+const MIN_LENGTH = 10;
+
+// Define a minimum length validator
+const minLengthValidator = {
+  validate: (extractionResult) => {
+    const textLength = extractionResult.text?.length || 0;
+
+    if (textLength < MIN_LENGTH) {
+      return {
+        valid: false,
+        error: `Text too short: ${textLength} < ${MIN_LENGTH}`,
+      };
+    }
+
+    return {
+      valid: true,
+      error: null,
+    };
+  },
+};
+
+try {
+  registerValidator(minLengthValidator);
+  console.log(`Min length validator registered (threshold: ${MIN_LENGTH})`);
+} catch (error) {
+  console.error("Failed to register validator:", error);
+}
+
+// Now extract with validation enabled
+const pdfBytes = new Uint8Array([
+  /* PDF content */
+]);
+const config = {
+  ocr: null,
+  chunking: null,
+};
+
+const result = await extractBytes(pdfBytes, "application/pdf", config);
+console.log("Validated result:", result);
+```
+
+This validator ensures extracted text meets minimum quality standards by checking length.
