Latest release

Foxit 10.1

Foxit PDF SDK for Desktop 10.1.0 supports PDF/E and PDF/X standards in preflight checks, enhances the conversion workflows and OCR capabilities with the support of multi-threaded/multi-core processing and additional options, and improves the performance in document optimization and form file import processes. It also adds new APIs in modules like search, image processing, and text processing to deliver a streamlined workflow.

Foxit Conversion SDK 2.1.0 brings enhanced features to PDF2Office and Office2PDF, providing users with a more versatile and efficient document conversion experience. For PDF2Office, users can now convert the restricted PDF files and benefit from additional options to remove trailing spaces from the output, specify Excel workbook settings, and control whether to include images or insert page breaks during conversion. Office2PDF introduces the support for outline conversion in Word2PDF, and offers workbook conversion options in Excel2PDF.
