I host this at home. I don't use it myself, I can use the linux CLI tools that its based on. But I prefer my wife to use this to convert/split/etc. her pdf files this way instead of using some random website or app (that uses the same cli tool anyway).
She doesn't mind either way. Seems to work well enough for her use cases.

Suggestion is to use a free Pdf xchange editor by tracker software. And print the document to pdf when done.

I'm running this in a container on my nas. There isn't anything to maintain with tools like this. If setup, properly - they keep running unless stopped. They can even be auto-updated when their is a new image. I have several types of utility apps I'm self-hosting. I rarely have to do anything other than keep the OS updated.

I am sorry. I was under the impression that, at least for some features, Stirling PDF also uses pdfjam or similar, instead of wholly delegating to PDFBox. I think the point still stands, that there are powerful cli tools and I wouldn't consider running this container just for myself.
Probably anybody who can get this docker container running, can use appropiate open source cli tools. So one would wonder about the target audience. I don't. ;)
But I do indeed LibreOffice's command line conversion features.

From the README: “Stirling PDF does not initiate any outbound calls for record-keeping or tracking purposes”. Beyond auditing the code, how could a potential user verify this claim in advance, and how can a web-based app help support such a claim (in particular when the app does need to make some web requests to operate, but only to a restricted list of URLs that might be listed in a manifest along the lines of a Content-Security-Policy for instance)?
This is a concrete problem when deploying apps that need the user to “upload” some sensitive content.

It seems that there is some missing tooling to make this convenient.
You can run a local bundle of HTML/JS/WASM in a web browser instance that you isolate (for example with firejail) to prevent network access. You distribute as a zip/tgz, but it's not obvious how to handle updates without a full redownload. Distributing with a full Electron-like interface is obviously overkill.
If you're running a web app that's hosted elsewhere (which will be much more convenient for most people), your web browser or the software isolation functionality (or firewall/proxy) needs to distinguish between the initial resource loads (approve) and later sneaky logging requests (ban).
There are Android applications such as TrackerControl that have related functionality (operates as a local VPN to filter all network requests and block tracking) but I don't know of convenient tools for the desktop (Linux, in particular).

Sure, but these types of applications are running in a web browser sandbox, which benefits from enormous engineering resources to protect the host computer from malicious actions by the remote code. I'm wondering whether this execution environment (augmented with some policy mechanism to allow apps to declare their URL access needs, a little like an AppArmor or network firewal policy) could also provide some guarantees concerning privacy or information security.

in particular when the app does need to make some web requests to operate
A web app doesn't need to make an outbound web requests to operate. A user interacting with a web is the one initiating the requests.
You can give the access to the up through a HTTP proxy and you can filter out any outbound requests from the web app or even not configuring the network routing for the server hosting that app. That leaves you with only JS initiated requests in the rendered pages of the app.

One thing I think is really lacking from the PDF ecosystem is good open-source tools around signing. PDF signatures are something that is legally important in a lot of the world with regulations like eIDAS. Unfortunately it's extremely difficult to cryptographically sign PDF documents with tools other than Adobe's and some other (often more sketchy) proprietary tools. Even if you figure out how to use stuff like LibreOffice or poppler to sign, you'll struggle to obtain certs that will validate without spending an arm and a leg.
I really hope that someone will decide to step in and become the Let's Encrypt of PDF and S/MIME certs, because that will improve public trust significantly.

Absolutely, and that's what I tend to do with my documents IRL, but I think it would be really nice if we could move to a world where signing documents digitally actually meant something more than `signature.png`.
In the EU, in order to have a legal guarantee of being treated as the same as a handwritten signature in all member states, you have to meet "Qualified Electronic Signature" level, which means cryptographic signatures and the involvement of some kind of trust services provider who validates the certificate used to sign. In practice this is rare, and ordinary electronic signatures a la Preview work for most things.

involvement of some kind of trust services provider
Marketplace at least in the US has shown that once you have this, the actual cryptography really doesn't matter. All anyone seems to care about seems to be "We are company X and have been doing this business for Y years and here's our standard operating policy. We emailed address A at time T1 and the person reading that email address used our online services to electronically 'sign' the pdf P at time T2."
Everyone trusts Adobe/Dropbox/et al to make that claim, nobody cares about certificates and what not.

Not the same thing.
- Libreoffice can edit Word and Excel files.
- There are several tools to read a PST file. Anyway… pst files are not commonly being shared with other people so the need to accessing it is uncommon unless you already use outlook.
- Autocad and Quickbooks are far less used (less people) than PDF.
I also wonder why there are no more tools to edit PDF files. Maybe licensing issues?

You are correct. Just because Libreoffice can mangle a docx file doesn't make them truly comparable.

Manipulation and signing is the easy part. Robust storage, retrieval and deletion aren't so easy.
Reputation often matters more than price in this area, because the pricey services amount to peanuts compared to the business as a whole. It's like doing price optimisation on toilet paper in the office. And reputation is generally interpreted as a proxy for reliability and a guarantee that there will be someone to sue if things go bad.

I once used it on a pdf file with a scanned text form trying to make it more contrast, as the scan was hardly seen. What I needed was basically just making dark stuff darker (up to the point of making it black) and maybe a bit thicker to make it more visible.
The tool failed to help me with such a seemingly menial task, the improvement was very small. I even tried to repeat the step multiple times, but after like 2nd use there were no visual differences anymore (but the file's size kept actually changing).

And yes, Master PDF Editor is an amazing piece of software! It makes creating PDF forms so easy that every time I get a PDF to fill out, I make it a form and send back an empty copy too so whoever sent it to me can use that instead. I've gotten a few smaller organisations to start using mine instead.

Is there a PDF templating tool that lets you GUI modify elements on a PDF to be used to generate reports and invoices for example ?
Backend has Python and preferably agpl
so do we trust it?
The claim, or the software? If the software was developed by ChatGPT it probably sucks. If it wasn't developed by ChatGPT, its author is a liar. So either way, fuck it.
Who cares if it was developed by ChatGPT if it actually works? Why not try it out first before crapping on someone's hard Open Source work?
Yeah let me waste a shitload of time on possible low-quality shit that might have spyware. Based on the advertisement I'm not convinced. I want PDF tools developed by experts, not monkeys pounding on keyboards or shysters who push stupid gimmicks.
PDF software / readers are reliably the least reliable, most likely to have security issues programs on any given machine. I for one would not run C code blindly copied from ChatGPT carelessly.
In this case I think the actual PDF bits are command line tools written by humans though, and just the web wrapping (some small initial piece of it) is originally from ChatGPT.
I once tried 3 hours to get ChatGPT to write a correct cubic interpolation function. Everything it wrote was either not cubic or not an interpolation function (the resulting curve didn't pass through the input points).
So yeah.
Not sure what your point is. I probably couldn't write a correct cubic interpolation function in 3 hours if you stuck me in an empty room and kept giving me the same instruction with a small change every time. But I've definitely written software as complex as this project basically from memory with only the occasional glance at some framework docs.
Leetcode is a meaningless metric when evaluating application developers.
What are you talking about?
This was an example of how I gave a LLM clear instructions on a function that is known to the internet. If I told you get to use google you probably could solve this "leetcode" task in 10 minutes.
So I picked a random known algorithm and asked ChatGPT to write a function with it, just to test it.
I agree that leetcode is a useless metric, but nobody informed me that something simple like cubic interpolation belongs to this.category now. Maybe I should re-evaluate my career.
I'm just saying that writing a small function that has to be perfectly correct is a very different task from from writing a small web app where the space of possible solutions is incredibly large.
LLMs don't have perfect recall, so it has to reconstructtthe answer from the information it retained from training. Your example is like asking it math problems: unless it had both seen and retained the specific one you've asked it, it can't answer correctly because doesn't have the capability to reason about the problem and solve it. But something like writing a web app is closer to writing a story, where each next block it spits out doesn't have to be exactly correct, it just has to get the job done.
As for leetcode, I guess it depends on your field, but my logic is this: if I came to an interview and was told to write a microservice that receives a POSTed file, extracts some data and puts it in a DB, that's a solid work-relevant skill test. But if they asked to to write some interpolation functions, I'd consider that a leetcode interview - closer to math than programming, not a good indicator of job ability, not representative of the kind of work I'll be doing.
I wonder what the point of that sentence is - to get picked up by HN? Kinda like how any product or service even tangentially related to data suddenly has 'by the way also AI and stuff' added somewhere on their landing page. You don't see 'Developed using intellisense' used in READMEs.

Yes, it would be a great idea to update the wording as there is no way to derive that from the current one.
Even being sympathetic, my thought reading this was "probably bad code quality/rotten core despite the great feature set".
You can have a "History/Background/Origin" section where you put exactly what you wrote in your comment and it will be fine.
This notwithstanding, thank you very much for developing this app! I will look into deploying it on my server, it will be of great help to people around me who often need manipulating PDFs but are not super technical!
That's amazing. What a time to be alive.
For me it means:
1) don't expose it to public internet
2) don't give it untrusted input
Which highly reduces the usability factor for me.
