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.

This looks great!
Can you use it to overlay text fields and fill them?
Most of my uses are basic. Like filling out a PDF form that doesn't have proper form entry fields. These are usually older government or bureaucratic/healthcare/school forms.
I end up adding text boxes and entering values, or adding an X on top of a checkbox, adding a signature PNG file and scaling it to fit the size. Sometimes I have to add a highlight overlay. Then I save it all as a single flattened PDF file.
Amazingly, this is hard to do in Acrobat and a lot of apps. I end up using a janky, 10-yo desktop app that is no longer supported.
You mean XFA forms? Then yes it supports it
Went to look up what XFA forms were (https://experienceleague.adobe.com/en/docs/experience-manager-learn/forms/document-services/pdf-forms-and-documents).
Most of the non-fillable forms I encounter are what that document lists as "Traditional" PDF forms, likely generated using older tools from print streams. For example, a school athletics release form, or a membership application for a small organization. None of them have any fillable PDF fields. The original expectation might have been to download and print out the PDF, hand-fill it, then fax the result back.
I'll dig up a form like that I had to fill a few weeks ago and give it a try.
OK, just tried it with one of those old forms. Added a text field overlay and a signature. Even flattens before saving. Works great. Awesome, thanks!
Awesome!
