We’re excited to share GroupDocs.Conversion for .NET 25.9 — a focused upgrade that gives you finer control over fonts, a smoother path from large PDFs to Markdown, and quality‑of‑life options for spreadsheets and plain text conversions. It also rolls up several stability fixes you’ve asked for.
What’s new in this release
Smarter font control. You can now declare explicit font transformations during conversion for WordProcessing and PDF inputs. That means cleaner brand alignment (e.g., mapping “Times New Roman” → “Tahoma”), better handling of mixed documents, and more predictable output across platforms.
Lean spreadsheets. Converting data tables that carry header/footer rows? You can now skip headers and/or skip footers during spreadsheet conversion — keeping only the content that matters in the result.
Markdown at scale. Converting large PDFs to Markdown is now more reliable thanks to chunked processing under the hood, reducing memory pressure and making long‑running jobs easier.
Consistent text rendering. Plain‑text conversions can adopt a default font you choose, so TXT → PDF/WordProcessing outputs look consistent on every machine.
Fixes and enhancements
- Filename preservation when intermediate conversions occur.
- More robust MSG → PDF processing.
- PDF → PDF/A font substitution behavior refined for archival outputs.
- Evaluation mode respects trial page limits for diagram → web conversions.
- Additional tweaks across format compatibility and stability.
Documentation
- API reference and guides for the new options (font transformations, skip header/footer, default font) are available in the release notes.
