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.

Great project. I like the 1-star reviews complaining about the lack of advertising and tracking.
haha thanks
Lol wait seriously? Surely those are a joke.
Can it also redact text from documents without allowing you to just copy and paste it back out again?
Asking for a friend.
Yes! It performs true redaction. You can find it in the editor tool
It is a civic duty to redact certain papers incorrectly.
Certain files, involving a certain island.
Are there ways to use it via an API? In particular I’d love to be able to programmatically submit a Word or Excel document and receive a PDF back
As its fully client side, it doesn’t expose any APIS. HOwever, I am writing an API only version of bentopdf on Rust
You’re doing the lords work my dude. There are not enough ways to thank you for your work
I use this already. Works great. Thanks for your hard work on this.
Glad it helped!
Thank you so much. Why did you start this project, which certainly involves a lot of work? ( aka why are you so cool?)
Thank you! It started off as a simple tool as I wanted to merge PDFs visually by applying page ranges and I couldn’t find any offline tool for that. I happened to then post it on reddit, and people asked me to open source it. After which I kept adding features on request and here we are 😂
You’re great for making this so everyone can use it. Thank you
(:
The day I can digitally sign PDFs from this, it’d be the PDF editor. You’re doing the Lord’s work, thank you very much for this!
It’s actually coming up in next release (: You will be able to sign with PKCS12, PFX and PEM certificates. And also validate them
Oh, wow, thank you very much for this!!
What about PGP ?
yes that too
So just got this up and running yesterday and today my wife used it for the first time. She did what she needed to do, but we may have come across a bug. I don’t know. She had to take a 72 page PDF and break it out into multiple smaller PDFs. While she was doing that, multiple pages in the preview window would keep going blank/white. Not sure if you’re aware of something like that, if not I can try to reproduce and grab logs and post them on github.
yes please that’d be helpful
Thanks for this! I saw this post yesterday, and decided to check it out. I installed it locally on my laptop, and am evaluating it for work. If I recommend it for use, we’ll get a license :).
Since the idea would be to replace Adobe for non-Pro (and maybe some Pro accounts), ease of use for low-tech users is at the front of my mind. Not being able to “set as default” for PDFs is not ideal, but I understand the limitation comes from running in the browser. Is there some way to open the PDF, and then choose which tool to use? Rather than how it seems now: choose the tool/function, then upload the PDF.
In next week we are going to be releasing Desktop apps, so you can download it and then set as default viewer
what is the reason to put that tool into a browser? if i use the thing on my private computer, it increases complexity compared to a local installation (not an issue for many ppl here, but for my grandma surely). if i use it on a corporate environment, wouldn’t more employees use it if it was the default PDF viewer on their managed device?
what did i miss?
Yes, as arthor mentioned it is supposed to be a self hosted tool. But since it’s client side and just a bunch of static files in the end, I will soon be porting it for all major platforms as an installable using Tauri
That’s excellent news! Is the github page linked above the best place to find out about that as soon as it’s ready?
Been using this for a while now, wife and kids are also very pleased with it. Easy to use and great layout, thank you so much!
Does each user have their own account? Or can anyone and everyone see all the pdfs? Or are the pdfs only stored for the duration of the browser session?
There are no accounts or signup. All the processing happens locally in your browser. In fact, you can even use it offline once the page is loaded, and only you have access to the PDFs
Everything local, I assume, means no upload? My dad does house inspections and so there’s like 4 or 5 pdf forms he fills out all the time. If he were using this, would he upload the template every time, or could he upload it once and then fill it out multiple times?
I assume also that it wouldn’t keep a history of each finished file, and it’s all ephemeral?
It never keeps any history, the TTL for the document is only as long as you are not done with the processing. There is no template system now. However I am planning to include a JSON based templating system which you can upload once and save and can be reused to auto fill forms
I’ve used Stirling pdf in the past. How does it compare?
a small question, if I may.
When I worked in technical support for a popular phone brand a lifetime ago, I had to make clickable “navigatable” pdfs. Create empty objects around apps and settings so that technicians could help clients without having access to their phone or device with current OS update. I would update mine and take screen shots then convert those with clickable objects to switch to the correct page to act as a sudo phone/tablet. Is this something that BentoPDF can do?
Currently there’s no such feature
