IronPdf for Java v2026.4.1
Enhancements
- Improved PDF rendering performance by reducing internal render calls and reusing browser tabs to minimize startup overhead
- Added compressAndSaveAs() method to compress a PDF and save it directly to a file path
- Deprecated compressImages() in favor of compressAndSaveAs(), compressPdfToBytes(), and compressPdfToStream()
Bug Fixes
- Fixed memory leak in replaceText() where repeated calls caused increasing memory growth (93–97% reduction)
- Fixed buffer over-read in metadata retrieval that could cause crashes or data corruption
- Fixed an issue where PDF/UA conversion removed CSS overflow:hidden clipping, ensuring clipped images render identically to standard PDF output
- Fixed an issue where signatureName was always empty when verifying signatures created by external signers such as Adobe Reader
