Hi folks!
I’m the creator of BentoPDF. It is an open source PDF toolkit that runs entirely in your browser. Your documents stay private, by design.
BentoPDF started as a small side project, but over time it has grown into something much bigger. With our latest major update, BentoPDF now includes 100+ tools, all running fully client-side.
You can do the basics like merge PDFs(while preserving bookmarks), split documents, extract or delete pages, reorder files, rotate pages, and compress PDFs. Thee are also some advanced tools.
You can edit and annotate PDFs directly in the browser: highlight text, add comments, draw shapes, insert images, fill(including XFA) and create forms, manage bookmarks, generate tables of contents, redact, add headers, footers, watermarks, and page numbers.
BentoPDF also supports an extensive range of file conversions. You can convert Word, Excel, PowerPoint, OpenOffice, Pages, CSV, RTF, EPUB, MOBI, comic book formats, and many more into PDFs, and also convert PDFs back into Word, Excel, images, Markdown, CSV, JSON, and plain text.
For images, BentoPDF supports a massive variety of formats, including HEIC, WebP, SVG, PSD, JP2, and and aalso other formats such as EPUB, CBR/CBZ. You can convert images to PDFs, extract images from PDFs in their original format, or rasterize PDFs with full DPI control.
There are also organization and optimization tools: OCR, PDF/A conversion, booklet creation, N-up layouts, page division, attachment management, layer (OCG) editing, metadata inspection and editing, repair tools, and advanced compression algorithms that rival commercial solutions.
The latest update also includes AI ready extraction tools to export PDFs to structured JSON, extract tables as CSV/Markdown/JSON, and prepare PDFs for RAG and LLM workflows.
All of this works entirely in the browser, without accounts, uploads, or tracking.
This is my first post here and I hope you like it. Any feedback or feature requests are appreciated. Thank you.

sorry but this is the first time I am hearing of a CAC card. Can you give me more details. I can check it out then
No problem: https://en.wikipedia.org/wiki/Common_Access_Card
Essentially it's a physical token containing a certificate. I can then put that card into a CAC card reader and authenticate with it and a PIN that I setup on my card.
I can then also sign PDF signature blocks with the cert on the card. I have only found this ability in Adobe Acrobat. The signature block in Adobe is different from just their regular sign location for digital ink. I've never made a PDF with one of those blocks, I've only just signed them so I'm not sure what exactly that kind of signing block is called.
So bottom line, it's a physical card with a certificate loaded on it. Adobe can read that cert and use it to sign signature blocks inside a PDF.
