Hello folks!
I would like to share an update about BentoPDF. It's an open source privacy first PDF toolkit that runs in your browser.
1. You can now actually edit text inside PDFs
BentoPDF now allows you to click existing text, edit it, and have the text reflow while preserving the original fonts and styling.
It also includes:
- Bold, italic, underline, strikethrough, superscript, subscript, font family/size, colours, outlines, character spacing and line spacing
- Left, centre, right and justified alignment
- Bulleted and numbered lists with indentation
- RTL and LTR text alignment
- Find and replace across the document
- Edit images by rotating, flipping, duplicating, resizing or deleting them
- Object alignment, distribution, rotation, flipping, duplication
Please note this is a work in progress. You may encounter bugs, which you can report and I will look into.
2. Hyper Compress
Hyper is an open source PDF compression engine built to solve specific problems.
- Compression sometimes returns a file larger than the original. Hyper's result is always binary: it either produces a smaller PDF or returns the original. This helps create predictable workflows.
- Hyper includes a true lossless mode. It preserves searchable text, document structure and PDF conformance, rather than rebuilding the document from scratch like Ghostscript.
- It runs everywhere: CLI, Node SDK, C API, self hosted service, and WebAssembly build.
Repository and benchmarks: https://github.com/alam00000/bentopdf-hyper-compress
I also compared it to Adobe's compression API, but only managed around 100 PDFs where results were within 5%. Testing on a bigger corpus got expensive.
3. Kura
Kura is a PDF standards, conversion and preflight engine.
It supports:
- All 11 PDF/A conformance levels: PDF/A-1a, PDF/A-1b, PDF/A-2a, PDF/A-2b, PDF/A-2u, PDF/A-3a, PDF/A-3b, PDF/A-3u, PDF/A-4, PDF/A-4e and PDF/A-4f
- Accessibility: PDF/UA-1 and PDF/UA-2
- Print production: PDF/X-1a, PDF/X-3, PDF/X-4, PDF/X-4p, PDF/X-5g, PDF/X-5n and PDF/X-5pg
- Engineering and variable data printing: PDF/E-1 and PDF/VT
- E-invoices: Factur-X, ZUGFeRD, XRechnung and Order-X
- 396 bundled print-preflight profiles
It has been tested against several standards suites, including the veraPDF corpus, Isartor, BFO, Ghent Output Suite 5.0, the PDF/UA Reference Suite and Cal Poly's PDF/VT suite.
Across 30,677 PDF conversions it had zero crashes and zero timeouts, with a 0.05 second median conversion time.
Like Hyper, it ships as a CLI, C library, npm package, Docker image and WebAssembly build.
Repository and benchmarks: https://github.com/alam00000/bentopdf-kura
The release also contains other improvements and bug fixes: https://github.com/alam00000/bentopdf/releases/tag/v2.8.8
Thank you and have a great weekend!

Pic is how I feel acquiring more software to replace my Big Tech dependency.
(Not all services could be listed here, obviously. Just the ones I personally use)

If it helps others this was my config. To be honest I have a weak grasp of what it actually does so there might be some security issues with it.
Apparently you can also add lemmy as a search engine. Will work on that later.
