BentoPDF Release Notes

Dad Joke Of the Release

What do you call a bee that can't make up its mind? A maybe 🤣

The Biggest Release of BentoPDF yet!

This is the biggest release of BentoPDF. BentoPDF can now edit text, image, shapes in BentoPDF and there are two new engines Kura and Hyper Compress. Detailed Explanation is below.

PDF Text Editing

BentoPDF can now edit the actual text inside a PDF. You can click any paragraph and type. Text reflows live, fonts and styling are preserved, and everything runs entirely in your browser, as always.

• Edit in place with live reflow, real font matching, and word wrap that follows the original layout
• Full styling: bold, italic, underline, strikethrough, superscript, subscript, font family and size, text colour, outline colour and width, character and line spacing
• Paragraph control: left / centre / right / justify alignment, bulleted and numbered lists with indent levels, and left-to-right and right-to-left text
• Find & replace across the document, plus spell-check with a personal dictionary and per-language switching
• Images: add, replace in place, or export a PNG, edit it in any app, and have your saved changes re import automatically
• Objects: align, distribute, rotate, flip, duplicate, and reorder front to back. Even commercial software like Apryse and Nutrient do not support this
• Accessibility: alt text for tagged PDFs, and reading-order text export …

[!WARNING] This release addresses security vulnerabilities (GHSA-wh78-rcw2-hhg9, GHSA-5xjf-rr5x-pcfj, GHSA-cx8x-7rrr-r9x8) affecting all versions up to and including v2.8.6. All users are strongly advised to upgrade to v2.8.7 immediately.

Full technical details will be published after the coordinated-disclosure window has passed.

With thanks to @thefoulowl, @alhamrizvi-cloud, and @de3erve-hunter for responsibly disclosing these. ❤️

A note from the maintainer

I genuinely appreciate people taking the time to look into BentoPDF's security with thoughtful reports that make the project better, and improve the project's security.

But having said that, there has been a big problem. Since LLMs became widely available, a large share of incoming security reports are low effort, machine generated submissions describing, at best, minor bugs, not vulnerabilities, and certainly not CVEs. In one such instance, I received over twenty such "CVE" reports from three different accounts within about thirty minutes which is of course not humanly possible to write with detail in such a short stretch. But none of which held up, and all of which were clearly LLM generated. Reviewing each of them carefully still took me a week …

A note

Hey everyone! Hope you are well.

The past few weeks I've been working on reducing BentoPDF's third-party library dependencies. Going forward, the core PDF stack will be just three libraries: pdf-lib.js, qpdf, and PDFium. Progress has been solid so far.

I also fell deep into a rabbit hole with PDF compression, and I think I've landed something genuinely interesting: better raw compression than Ghostscript, while preserving PDF fidelity. I'll be open sourcing it soon after more testing, and it'll become BentoPDF's core compression engine. More updates coming shortly!

What's Changed

1. Multi-tool: drag-and-drop for PDFs and images.

• The PDF multi-tool now accepts both PDF and image files via drag-and-drop

2. Split PDF Refactor

• This fixes a long-standing size problem: when a PDF shared resources (fonts/images) across pages, extracting just a few pages could produce a file nearly as large as the original.

• The single "Download as ZIP" checkbox conflated what you get with how it is packaged. It is replaced by a clear choice: Single combined PDF vs One PDF per range/page and ZIP packaging is now applied automatically whenever more than one file is produced.

What's More

• fix(md to pdf): restore mermaid flowchart node labels. Fixes #738 by @mondeep31 in https://github.com/alam00000/bentopdf/pull/739 ❤️
• chore(i18n): add Slovak language by @marek-mraz in https://github.com/alam00000/bentopdf/pull/737 ❤️ …

What's the easiest building to lift? A lighthouse 🤣

(This release is later than I would have liked. The past few weeks I've been under the weather and pretty burnt out, so v2.8.5 sat finished for longer than it should have. Thanks for being patient ❤️)

What's Changed

1. Custom Rotate

• Improved angle input handling, rotation utilities, and a smoother UX for fine-grained rotation. Thanks to @quhxl for the contribution.

2. Alternate & Mix Pages

• Alternate and mix pages are now in workflow builder. Fixes #684

3. Helm Chart Auto Update

• Helm chart version now auto updates with each release. Fixes #680

4. New Option in Merge

• By default merge tool used to keep Keep original page labels from each file intact. Now users have the option to opt out from it via a checkbox. Fixes #676

Bug Fixes 🐛

• OCR Arabic + Latin — Fixed mixed Arabic and Latin OCR output where English text appeared as empty boxes when run alongside Arabic. Dual font loading now covers any non Latin script combined with Latin. Also fixes the bug in #724

• HEIC in workflow — HEIC images are now correctly accepted in the image to pdf workflow node. Fixes #703

• Email parsing reliability — MsgReader CJS/ESM interop fix for .msg files. Fixes #701

• Sign PDF signature editor width — Editor now fills the full available width like the rest of the tool. Fixes #653 …

[!WARNING] This release addresses the security vulnerability GHSA-6vh8-4frx-647f which affects all versions including and prior to v2.8.2. All users of BentoPDF are recommended to upgrade immediately to the latest version 2.8.3

A note of thanks

A huge thank you to @Astaruf for discovering this vulnerability and reporting it to us through responsible disclosure. Independent security researchers like Lorenzo are what keep open source software trustworthy, and we are genuinely grateful for the care and professionalism shown throughout the process. This is exactly how coordinated vulnerability disclosure should work, and BentoPDF is safer today because of it. Thank you. ❤️

What's Changed

Every change between two PDFs including text edits, style tweaks, moved paragraphs, image modifications and annotation diffs is now detected, categorized, and navigable.

What's New
