+#### 🧊 `Task<double> GetZoomFactorAsync()`
+Returns the current zoom factor. A factor of `1.0` means 100%.
+
+#### 🧊 `void SetZoomFactor(double factor)`
+Changes the zoom factor to the specified factor. The zoom factor is the zoom percent divided by 100, so 300% = `3.0`. The factor must be greater than `0.0`.
+
+**Parameters:**
+- `factor` - The zoom factor
+
+#### 🧊 `Task<double> GetZoomLevelAsync()`
+Returns the current zoom level.
+
+#### 🧊 `void SetZoomLevel(double level)`
+Changes the zoom level to the specified level. The original size is `0` and each increment above or below represents zooming 20% larger or smaller to default limits of 300% and 50% of the original size, respectively.
+
+**Parameters:**
+- `level` - The zoom level
+
+#### 🧊 `Task SetVisualZoomLevelLimitsAsync(double minimumLevel, double maximumLevel)`
+Sets the maximum and minimum pinch-to-zoom level.
+
+**Parameters:**
+- `minimumLevel` - The minimum pinch-to-zoom level
+- `maximumLevel` - The maximum pinch-to-zoom level

+```csharp
+// Set the zoom to 150%
+webContents.SetZoomFactor(1.5);
+
+var factor = await webContents.GetZoomFactorAsync();
+Console.WriteLine($"Current zoom: {factor * 100}%");

+webContents.OnZoomChanged += (direction) =>

+
+> **Note:** The zoom factor is shared by all windows using the same session partition. Assign a unique `WebPreferences.Partition` per window if each window should keep its own zoom.
