We’re happy to announce the GroupDocs.Conversion for .NET 25.11 release, available as of November 2025. This update adds two major features, introduces a new public API property, and resolves ten conversion‑related bugs.

What’s new in this release

New features

ID Feature
CONVERSIONNET‑8050 PSD/PSB support on .NET 6 – you can now convert Photoshop (.psd, .psb) files when targeting .NET 6.
CONVERSIONNET‑8082 Advanced PDF page‑resize scaling modes – four new ResizeMode options (ScaleToFit, ScaleToWidth, ScaleToHeight, ScaleToFill) give fine‑grained control over how content is scaled when converting to PDF.

Public API change (backward‑incompatible)

The PdfConvertOptions class now exposes a ResizeMode property (type PageResizeMode). The default remains AlignTopLeft, which keeps the original layout unchanged. Switching to any of the new scaling strategies is as simple as setting the property before conversion.

using (Converter converter = new Converter("sample.pdf"))
{
    PdfConvertOptions options = new PdfConvertOptions();
    // Proportional scaling to fit the target page size
    options.ResizeMode = PageResizeMode.ScaleToFit;
    options.SizeSettings.PageSize = PageSize.A4;

    converter.Convert("converted.pdf", options);
}

For a complete reference, see the ResizeMode documentation.
