Hello @alexey.noskov,

my demo from https://products.aspose.com/html/zh/java/conversion/:

public class Test3 {
public static void main(String[] args) {
String documentPath = “/index.html”;
String outputPath = “/indexNew.pdf”;

    // Source HTML document
    com.aspose.html.HTMLDocument htmlDocument = new com.aspose.html.HTMLDocument(documentPath);
    // Initialize PdfSaveOptions
    com.aspose.html.saving.PdfSaveOptions options = new com.aspose.html.saving.PdfSaveOptions();
    options.setJpegQuality(100);
    // Output file path
    // Convert HTML to PDF
    com.aspose.html.converters.Converter.convertHTML(htmlDocument, options, outputPath);
}

}

@Rivan

Looks like a font-related issue. Can you please try installing windows fonts in the MAC OR use

new FontsSettings().setFontsLookupFolders(new String[]{ "p:/tmp/"}, true);

before performing the conversion. Please let us know in case issue still persists.

@asad.ali Hello，Thanks for your help。
but，I can’t find the parameterless construction of FontsSettings in 23.1 aspose-html，need the fontFactory; eq:
@z30
public FontsSettings(z11 fontFactory) {
this.fontFactory = fontFactory;
}

I try new methods，but same error.
String[] fontsFolders = { “/Users/rivan/Library/fonts/” };
//new FontsSettings(null).setFontsLookupFolders(fontsFolders, true);
Configuration configuration = new Configuration();
IUserAgentService service = configuration.getService(IUserAgentService.class);
service.getFontsSettings().setFontsLookupFolders(fontsFolders,true);
HTMLDocument document = new HTMLDocument(documentPath,configuration);
