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.

Can it also redact text from documents without allowing you to just copy and paste it back out again?

Asking for a friend.

    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 😂

    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

    Thank you so much for this. We just started using it at our school. We were using StirlingPDF, but they went open core 🫤. Personally, I like that there is no auth, it keeps it simple.

    Not sure, as I haven't used Stirling and at the same time I didn't make it to compete with other tools. Hence I never mention its better than xyz tool either on our github or website. Users would have to do their own due diligence in this case. However it does have the best bookmark tool in the market(yes, better than adobe acrobat) and also a form creator tool, among others, which you can't find in other OS tools.

    I understand and I wasn't looking for a "better or worst"assessment. I'll give it a try even if I haven't needed to manipulate pdfs. Always nice to add to the toolset.

    Honestly, I think this is just one where you try it for yourself. The compose file is about 4 lines long, I had the whole thing up and running in about 30 seconds (OK, 45; I forgot a port was already in use and had to redeploy).

    So far my one big complaint would be that the self-hosted version replicates the entire website, including all of the "Why choose Bento PDF" and "Try now" and so on. It'd be nice to just have the tools right there when I load it up. Other than that, well, it looks cool, I'll know more once I actually try out the available options.

    As someone who have been using both, you don't need an account to use bentopdf. All the data is processed locally, making it excellent for a single user scenario. I drink Sterling has a very handy omni-tool, but I dare say it's a matter of preference.

    I go with bento where I can, and use sterling as a fallback.

    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

  • source
  • hideshow 5 child comments
  • [–] 7 points 10 months ago* (1 child)

    Agreed. I spent a bit of time writing out a script for similar functionality for one of our business units, but I never was able to figure out how to convert excel sheets to a PDF to be able to merge them in the allotted time, so it just doesn't support them lol.

    But I can see why it wouldn't have an API, since the whole deal is it stays in your browser, and an API would mean sending the files to the server.

    Unsure it fits your scenario but you could use VBA. In my case, we collect data via Excel then they get populated into a Word report template, and finally export to PDF for project delivery purposes, all automated using VBA.

    I had no clue this existed!!! Thanks for sharing.

    Would you say that BentoPDF is an alternative to Adobe Acrobat and/or Bluebeam Revu?

    I use those for my job, but it'd be nice to have a FLOSS alternative as a backup

    I use this at home and I’m thinking of setting this up at work, to prevent my colleagues from using shady PDF-sites, for merging or splitting PDF-files.

    Nice, and thanks for posting here! We have a lot of discussion about projects, and it's helpful when the creator/developer is around to respond to comments directly 😄

    I saw the update on GitHub about the goal of working on it full time. I also swapped over from StirlingPDF and I'm excited to see where this project goes. Best of luck :)

    It's not important but I guess it doesn't support auth? I've only got time to do a quick glance right now so I might have missed something.

    I think a lot of people's use cases might be to integrate with other tools in their self-host stack like Authentik (could be solved by adding proxy auth if nothing exists natively) and Nextcloud or other filesharing/storing solutions.

    If there aren't any capabilities like that then it could be food for thought for expansion. Otherwise great job! Right now it's still an upgrade from various shady PDF tool websites where you still have to download the PDF from your server to upload and process the files.

    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?

    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

  • source

  • hideshow 3 child comments
  • [–] 1 point 10 months ago

    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.

    I don't suppose you're able to sign PDFs with something like a CAC card right? Is that still wholly in the realm of acrobat?

    Literally the only thing I need another software to do so I can finally uninstall the last Adobe product from my VM. I'm running Linux so getting this functionality in Linux would be ideal. But since no one else has done it, I assume Adobe has some kind of stranglehold on that process?

  • source

    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

  • source
  • parent
  • hideshow 1 child comment
  • 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.
