To save a GdPicture image to a file, use one of the `SaveAs...` methods of the [`GdPictureImaging` class](https://www.nutrient.io/api/gdpicture/GdPicture.NET.14~GdPicture14.GdPictureImaging.html).

For example, the [`SaveAsPNG` method](https://www.nutrient.io/api/gdpicture/GdPicture.NET.14~GdPicture14.GdPictureImaging~SaveAsPNG.html) saves a GdPicture image to a PNG file. Refer to [supported file types](https://www.nutrient.io/guides/dotnet/about/file-type-support.md) to see available output formats.

Most `SaveAs...` methods use:

- `imageID` — The GdPicture image identifier.

- `FilePath` — The output file path.

- Optional format-specific parameters (for quality/compression/settings).

When you no longer need an image resource, release it with the [`ReleaseGdPictureImage` method](https://www.nutrient.io/api/gdpicture/GdPicture.NET.14~GdPicture14.GdPictureImaging~ReleaseGdPictureImage.html).

The following example saves a previously loaded JPG image to PNG format:

### C#

```csharp

using GdPicture14;
using System;

using GdPictureImaging gdPictureImaging = new GdPictureImaging();

// Create a GdPicture image from a JPG file.
int imageID = gdPictureImaging.CreateGdPictureImageFromFile(@"C:\temp\source.jpg");
if (imageID == 0)
{
    Console.WriteLine($"CreateGdPictureImageFromFile failed: {gdPictureImaging.GetStat()}");
    return;
}

// Save the GdPicture image as a PNG file.
GdPictureStatus status = gdPictureImaging.SaveAsPNG(imageID, @"C:\temp\output.png");
if (status!= GdPictureStatus.OK)
{
    Console.WriteLine($"SaveAsPNG failed: {status}");
}

gdPictureImaging.ReleaseGdPictureImage(imageID);

```

### VB.NET

```vb

Imports GdPicture14

Using gdPictureImaging As New GdPictureImaging()
    ' Create a GdPicture image from a JPG file.
    Dim imageID As Integer = gdPictureImaging.CreateGdPictureImageFromFile("C:\temp\source.jpg")
    If imageID = 0 Then
        Console.WriteLine($"CreateGdPictureImageFromFile failed: {gdPictureImaging.GetStat()}")
        Return
    End If

    ' Save the GdPicture image as a PNG file.
    Dim status As GdPictureStatus = gdPictureImaging.SaveAsPNG(imageID, "C:\temp\output.png")
    If status <> GdPictureStatus.OK Then
        Console.WriteLine($"SaveAsPNG failed: {status}")
    End If

    gdPictureImaging.ReleaseGdPictureImage(imageID)
End Using

```
