We’re excited to introduce GroupDocs.Conversion for .NET 25.8, packed with powerful features, performance enhancements, and essential bug fixes to deliver more reliable and optimized document conversions. You’ll find the full release notes here.

Major Features & Enhancements

  • SVG Cropping Support – You can now crop visible SVG content during conversion, giving you tighter control over layout and cleaner output.
  • Custom Email Attachment Icons – Want to include custom icons for email attachments during conversion? Use the new UseDefaultAttachmentIcons and AttachmentIcons options.
  • Expanded SVGZ Conversion Support – Convert SVGZ files seamlessly into word processing, presentation, and spreadsheet formats.
  • Extended Format Coverage – New conversion options include SVG/SVGZ to EPS and TeX (LaTeX). Plus, Web-to-PageDescriptionLanguage conversions are now faster thanks to eliminated intermediate steps.
  • Performance Improvements – Enjoy significantly faster application startup and more responsive initialization.

Key Bug Fixes

We’ve addressed a range of issues to ensure smoother, more reliable conversion experiences:

  • Resolved low image quality when converting certain SVGs to raster formats.
  • Fixed output inconsistencies in PDF to WordProcessing conversions—now correctly outputs DOCX/DOC formats.
  • Eliminated exceptions during PDF to JPEG conversion processes (errors like GroupDocsConversionException and ObjectReferenceNotSet).
  • Corrected formatting problems in RTF to PDF conversions.
  • Fixed exceptions thrown in SVGZ to WordProcessing conversions :contentReference.
  • Fixed “Index was outside the bounds of the array” errors when converting DWF to images.
  • Fixed an issue where the SetLicense method could not locate the license file in the current directory.
  • Enhanced compatibility for DOC to DOCX conversions :contentReference.

Public API & Breaking Changes

Here are the key API updates and new features:

  1. SvgLoadOptions Class – Now includes CropToContentBounds, allowing SVGs to be tightly cropped around visible content for cleaner conversion output: 
    var loadOptions = new SvgLoadOptions {
    CropToContentBounds = true
};
  2. EmailLoadOptions Enhancements – Two new properties:
    • UseDefaultAttachmentIcons – Toggle default attachment icons.
    • AttachmentIcons – Provide custom icons for specific attachment types:
    using (var converter = new Converter(source, loadContext => new EmailLoadOptions {
    UseDefaultAttachmentIcons = false,
    AttachmentIcons = new List<AttachmentIcon> {
        new AttachmentIcon("jpg",  File.ReadAllBytes("jpeg_icon.png")),
        new AttachmentIcon("pdf",  File.ReadAllBytes("pdf_icon.png")),
        new AttachmentIcon("docx", File.ReadAllBytes("word_icon.jpg")),
        new AttachmentIcon("_default", File.ReadAllBytes("not_found_icon.png"))
    }
})) {
    var options = new PdfConvertOptions();
    converter.Convert("converted.pdf", options);
}
