Two Content Extraction Workflows

Workflow	What It Does	Result
Workflow 1	Extract and convert each file separately	Individual converted files (e.g., doc-1.pdf, doc-2.pdf)
Workflow 2	Convert contents AND create new archive	New archive with converted contents

Workflow 1: Extract and Convert to Individual Files

Extract files from an archive and convert each one separately (no re-compression).

using GroupDocs.Conversion.Fluent;
using GroupDocs.Conversion.Options.Convert;
using GroupDocs.Conversion.Contracts;
using System.IO;

// ZIP contains: report.docx, summary.docx, analysis.docx
FluentConverter.Load("documents.zip")
    .ConvertTo((SaveContext saveContext) =>
    {
        // Create separate output file for each document
        string fileName = $"converted-document-{saveContext.ItemIndex}.pdf";
        return File.Create(Path.Combine(@"C:\output", fileName));
    })
    .WithOptions(new PdfConvertOptions())
    .Convert();

// Output: converted-document-1.pdf, converted-document-2.pdf, converted-document-3.pdf

Using original filenames:

FluentConverter.Load("documents.zip")
    .ConvertTo((SaveContext saveContext) =>
    {
        string originalName = saveContext.SourceFileName ?? $"document-{saveContext.ItemIndex}";
        string fileName = Path.ChangeExtension(originalName, ".pdf");
        return File.Create(Path.Combine(@"C:\output", fileName));
    })
    .WithOptions(new PdfConvertOptions())
    .Convert();

// Output: report.pdf, summary.pdf, analysis.pdf

Workflow 2: Convert Contents and Re-compress

Extract files, convert them, and package into a new archive:

using GroupDocs.Conversion.Fluent;
using GroupDocs.Conversion.Options.Convert;
using GroupDocs.Conversion.Contracts;
using GroupDocs.Conversion.FileTypes;
using System.IO;

FluentConverter.Load("documents.rar")
    .ConvertTo((SaveContext saveContext) => new MemoryStream())
    .WithOptions(new PdfConvertOptions())
    .Compress(new CompressionConvertOptions
    {
        Format = CompressionFileType.Zip
    })
    .OnCompressionCompleted(compressedStream =>
    {
        using (var fileStream = File.Create("converted-documents.zip"))
        {
            compressedStream.CopyTo(fileStream);
        }
    })
    .Convert();

// Output: converted-documents.zip containing PDFs

With password protection:

FluentConverter.Load("sensitive-files.zip")
    .ConvertTo((SaveContext saveContext) => new MemoryStream())
    .WithOptions(new PdfConvertOptions())
    .Compress(new CompressionConvertOptions
    {
        Format = CompressionFileType.Zip,
        Password = "SecurePassword123"
    })
    .OnCompressionCompleted(compressedStream =>
    {
        using (var fileStream = File.Create("protected-archive.zip"))
        {
            compressedStream.CopyTo(fileStream);
        }
    })
    .Convert();
