What's new 2026

What’s new in Aspose.PDF 26.1

In Aspose.PDF 26.1, we have added:

  • Performance improvements – resolved poor performance when adding text to documents (PDFNET-34609) and overall performance issues (PDFNET-58899).

  • Enhanced rendering accuracy – fixed missing vertical text on the left side of PDFs (PDFNET-38618) and corrected Chinese character rendering during PDF-to-PNG conversion (PDFNET-58950).

  • Improved HTML conversion – the API now respects line color in HTML-to-PDF conversion (PDFNET-38417) and fixed text overlap issues in XFA-to-Standard conversion (PDFNET-38458).

  • Bug fixes for document structure – NumberingStyle now works correctly for Heading objects (PDFNET-38421), and PDF-to-HTML now preserves highlighted text color (PDFNET-50941).
