+# Bank Statement Download Helpers
+
+Browser console scripts to save bank statements as properly named PDF files.
+
+---
+
+## ANZ — `anz-download-statements.js`
+
+### How to Use
+
+1. Log into ANZ Internet Banking → **View statements and notices**
+2. Expand all year sections so all statements are visible
+3. Open **F12 → Console**
+4. Paste the contents of `anz-download-statements.js` and press **Enter**
+5. You'll see: `✅ Download helper active!`
+6. Click each **Download** button — the PDF saves with a name like `ANZ-Statement-2026-02-February.pdf`
+7. Close the blob tab that opens, then click the next Download button
+
+### Output
+
+`ANZ-Statement-YYYY-MM-Month.pdf` (e.g., `ANZ-Statement-2026-02-February.pdf`)
+
+### How It Works
+
+Listens to ANZ's XHR API responses (read-only) and extracts the base64-encoded PDF data from the JSON response. Triggers a file download with a descriptive filename. ANZ's normal flow is unaffected — the blob tab still opens.
+
+---
+
+## Westpac — `westpac-download-statements.js`
+
+### How to Use
+
+1. Log into Westpac Online Banking → **Search for statements**
+2. Select the account and date range, then click **Search**
+3. Click **Display more** if needed to show all statements
+4. Open **F12 → Console**
+5. Paste the contents of `westpac-download-statements.js` and press **Enter**
+6. You'll see: `✅ Westpac download helper active!`
+7. Click each **Download PDF** button — the PDF saves with a proper name instead of opening in a new tab
+
+### Output
+
+`Westpac-AccountName-YYYY-MM-Month.pdf` (e.g., `Westpac-Altitude-Qantas-Black-Card-2026-02-February.pdf`)
+
+### How It Works
+
+Intercepts clicks on the Download PDF links, fetches the PDF using the existing authenticated session, and saves it as a named file download. Prevents the default behaviour of opening the PDF in a new tab.
+
+---
+
+## To Stop
+
+Refresh the page (F5) for either script.
