GoupDocs.Conversion takes too much time

We tried GroupDocs.Conversion and we have some questions:

We tried to convert a simple text file (~ 200 bytes) to PDF. But for some reason this process takes around 20 seconds. We tried the code from this example:

The Aspose.Total worked much faster.

Some additional info regarding our attempts:

License: we tried to run the above example without license and with a temporary license

Version: we tried the nuget package GroupDocs.Conversion v.23.11.0

Environment: we tried it locally (Windows machine) and on AWS (Lambda function)

We even tried to convert the same text file via online converter (Online file conversion | Free GroupDocs Apps). But this conversion taken around 2-3 minutes.

Could you let us know is it possible to improve this process somehow?

Could you please share the problematic TXT file? Do you face this issue for all ~200 bytes text files or with a specific one?

Hi @atir.tahir

Not sure I understood your question. We tried just one single text file only that takes around 200 bytes.

I have attached an archive with this file.


input_text_sample.zip (240 байтов)

Please try following code to improve conversion performance:

// Specify the path to the source text file
const string source = "input_text_sample.txt";

// Open the source text file as a FileStream using FileMode.Open
using (var fs = new FileStream(source, FileMode.Open))
    // Create a Converter instance with a custom loading function and WordProcessingLoadOptions for text files
    using (var converter = new Converter(() => fs, () => new WordProcessingLoadOptions
        // Set the format to WordProcessingFileType.Txt for text files
        Format = WordProcessingFileType.Txt
        // Specify conversion options, e.g., PDF conversion
        var options = new PdfConvertOptions();

        // Perform the conversion from text to PDF and save the result as "converted.pdf"
        converter.Convert("converted.pdf", options);
