+### Preserve fonts when saving PDF (Blazor WebAssembly)
+
+In Blazor WebAssembly, to preserve fonts in exported PDF use the `CustomFont` property of the SfSpreadsheet component. Provide local TrueType font (.ttf) files from wwwroot and reference them via the component.
+
+#### How to use
+- Place .ttf files under wwwroot (for example: wwwroot/Arial.ttf).
+- Mark each .ttf as Content so it is published to wwwroot.
+- Set the SfSpreadsheet.CustomFonts list with paths relative to wwwroot (for example: `"Arial.ttf"`).
+- Only local .ttf files are supported for WASM PDF export — do not use remote URLs.
+- Verify file name casing; paths are effectively case-sensitive on some hosts.

 ## New
 To create a new, blank workbook through the UI, select **File > New** from the **Ribbon**. This action initializes a blank spreadsheet component, ready for data entry or formatting. If unsaved changes are present, a confirmation dialog will appear, indicating that these changes will be lost. The dialog presents options to proceed with creating the new workbook by selecting **OK**, or to cancel the operation by selecting **Cancel**.
