Features & Upgrades

https://www.npmjs.com/package/@ironsoftware/ironpdf/2026.8.1/

Release Notes

• Added AES-128 and AES-256 PDF encryption support through PdfDocument.setEncryptionType(PdfEncryptionType)
• Added support for RFC 3161 trusted timestamps when digitally signing PDFs
• Fixed an issue where merging or inserting PDFs with nested bookmarks could flatten the bookmark hierarchy
• Fixed an issue where converting PDFs to PDF/UA could shift page content for documents with multiple content streams
• Fixed an issue where landscape rendering with responsive CSS or fit-to-page scaling could leave empty areas at the edge of the page
• Fixed a crash during PDF/UA conversion for certain PDFs and improved PDF/UA-1 compliance
• Fixed an issue where auto-sized HTML headers and footers could overlap page content on repeated renders
• Fixed digital signature validation for PDFs with nested AcroForm signature fields or trailing padding bytes

Features & Upgrades

https://www.npmjs.com/package/@ironsoftware/ironpdf/2026.7.2/

Release Notes

• Added ChromePdfRenderOptions.CssPageRulePolicy and header/footer overlap detection options to improve margin handling and prevent content overlap when rendering or modifying PDFs.
• Enhanced render timeout handling by detecting stalled PDF generation operations and returning clearer, more actionable error messages.
• Fixed an issue where PDF redaction could leave partial-character artifacts or remove excess content due to inaccurate text bounding boxes.
• Fixed an issue where digitally signed PDFs could produce invalid signatures when signed using signDigitalSignature(...).
• Fixed an issue where Advanced Compression did not apply image downsampling correctly, resulting in limited file size reduction for image-heavy PDFs.
• Fixed an issue where PdfGenerator.imageToPdf (and PdfDocument.fromImage) could generate blank PDFs for image filenames containing both spaces and multiple dots.
• Fixed an issue where multi-page TIFF conversion did not preserve per-page orientation and resolution for mixed-orientation PDFs.
• Fixed an issue where PDF signature timestamps could display an incorrect timezone offset during daylight saving time (DST).
• Updated internal dependencies.

Known Issues

Overlap detection inspects text and image content only; vector/path content (table borders, ruled lines) is not detected, so a Throw that doesn't fire is not a guarantee..

Features & Upgrades

https://www.npmjs.com/package/@ironsoftware/ironpdf/2026.6.1/

Release Notes

• Added AdvancedCompressionOptions and ObjectStreamMode for fine-grained PDF compression control, including image DPI downsampling, JPEG quality settings, structure-tree removal, and customizable optimization flags.
• Added FormManager.setFormFont, setFormFontFromFile, and disableFormFontFallbackAPIs to control or suppress automatic form-field font embedding.
• Fixed invisible or missing headers and footers on scanner-generated and browser-printed PDFs.
• Fixed an issue where copy-pages operations could drop form fields with shared widget annotations across multiple pages, causing visible fields to disappear in copied documents.
• Fixed incorrect Table of Contents page numbers for long headings that wrapped across multiple rendered lines.
• Fixed excessive PDF size growth when combining static-content headers/footers with dynamic content in large documents.
• Fixed IronPdfEngine queue deadlocks under concurrent load.
• Updated internal dependencies

Features & Upgrades

https://www.npmjs.com/package/@ironsoftware/ironpdf/2026.5.1/

Release Notes

• Added LinkAnnotation class for creating clickable links within PDF documents that navigate to specific pages and positions, with full BookmarkDestinations support
• Added full PDF linearization support: linearizePdfToBytes, linearizePdfToStream, saveAsLinearized, static linearizePdfBytesToBytes / saveAsLinearizedFromBytes, and isLinearized.
• Added automatic PDF bookmark generation from HTML headings (h1-h6) during rendering, including correct hierarchy, page mapping, and optional filtering by heading level or CSS selector
• Fixed intermittent SEGFAULT during process teardown and improved tab pool stability to prevent concurrent rendering issues and log spam
• Updated internal dependencies

Features & Upgrades

https://www.npmjs.com/package/@ironsoftware/ironpdf/2026.4.1/

Release Notes

• 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
• Added getVerifiedSignatures() method to retrieve verified digital signature details including signature name, signer contact, reason, location, date, and validity
• Deprecated compressSize() in favor of compressAndSaveAs(), compressPdfToBytes(), and compressPdfToStream()
• 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
