Show HN: Pdfwithlove – PDF tools that run 100% locally (no uploads, no back end)

https://pdfwithlove.netlify.app
122•pratik227•3h ago
Most PDF web tools make millions by uploading documents that never needed to leave your computer.

pdfwithlove does the opposite:

1. 100% local processing 2. No uploads, no backend, no tracking

Features include merge/split/edit/compress PDFs, watermarks & signatures, and image/HTML/Office → PDF conversion.

Oh cool.

Can we add workflows to this?

First merge all files then depending on output size compress to fit the size and other requirements?

Or take out page 35, then compress rest

Or extract page 2,5 and merge them and give me output withoit compress

pratik227•1h ago
Ah, cool idea. I’m currently integrating image processing features—crop, compress, and meme generation. Once that’s almost done, we can move on to integrating the workflow.
psychoslave•35m ago
Can't you already do that with pdftk and the like? And work LLM, just like ffmpeg you can generally get the right command quiet easily now.
2Gkashmiri•30m ago
But this is a self contained webapp. There are other tools that suppport similsr functionality
psychoslave•15m ago
Well, fine if it helps other users. Not sure I’m the expected audience.
TZubiri•1h ago
Feels like infringing on the ILovePDF trademark. (Backpiggying on an established brand to make it look like you are affiliated, or the actual brand)
pratik227•1h ago
Ah, I’m not sure. I’m not directly using their name, and it’s not related, right? It shouldn’t cause any issues, correct?
franze•1h ago
well you clearly state that your naming is based on their naming with this sentence "The Privacy-First Alternative to"

even if it might not stand before court it is enough for a lawyer to write you a letter that is not 100% baseless.

pratik227•59m ago
I see
TZubiri•45m ago
Law aside, it feels fake, phishy, like a pair of shoes that say Adibos.
srikanthdotch•55m ago
Looking at the site, I don't think there's a legal issue
Antibabelic•1h ago
Doesn't a time-tested solution already exist in the form of PDF24?
pratik227•1h ago
It's not just PDF i'm also working on image processing and all as well
zdc1•1h ago
Nice to have something that doesn't require Windows
burgerone•1h ago
How does it compare to stirling pdf?
pratik227•1h ago
I’m doing everything locally, with no pricing on the extension for now. I do plan to make it paid later, but since all processing happens locally, your files never leave your device and remain completely safe.

also not just PDF the image processing also WIP will be done by next week

TZubiri•1h ago
Might be better to provide a downloadable executable instead of asking the user to trust that the browser isn't doing what the browser was designed to do.
pratik227•1h ago
I plan to build a Chrome extension and am considering making it paid, around $2 for lifetime access. Also Desktop app is also good idea
sabdarmdhn•1h ago
Make the Desktop Version natively, even tho its time efficient to make it just Electron
pratik227•1h ago
yah noted I will do
niemandhier•1h ago
Extensions have the downside that a malicious actor can buy out the original dev and start using them as an intrusion point.
cluckindan•40m ago
Don’t make either unless you have the resources to support them. Anything paid is also a business process with tax implications.

Local-only web apps are great one-off projects, but extensions and native apps require much more maintenance.

wickedsight•1h ago
I can easily check network monitor in the browser to see exactly what a web app is doing.

Running an executable is a risk by default and the way it interacts with my network is way less transparent. I honestly prefer this in the browser.

matsemann•55m ago
Disagree, no way I'm downloading an executable from something unknown to modify a pdf.
pmontra•48m ago
I disagree on that. I think that the main value of this kind of tools is "no installation required".

There are already free PDF editors that can be downloaded and installed once forever. What I used most is Libreoffice Draw: it imports a PDF, edit it as if it were a file in its own format, export as PDF again. It's not the only choice. Firefox has had a vanilla PDF editor since last year: download a PDF or drag one inside the browser window, edit it, save it. It's enough to add a PNG of my signature and fill out forms.

Bewelge•1h ago
Great job! If it's all on client you should make a PWA out of it so it can be installed and used offline.

Built a client only webapp myself and offline usage is the main thing users ask about.

pratik227•1h ago
Yeah, I’ll do that. I have a Chrome extension that I’m planning to make paid, and I may also release a desktop version. I’m thinking of pricing it cheaply—around $2 for lifetime access
gregsadetsky•1h ago
Great work, thanks for sharing and congrats on the launch!

Very very small note - many clickable things on your site (the "explore" and "new task" buttons, the directory and blog links at the top, etc.) don't change the cursor to the css "cursor:pointer" (ie the clicky hand)

You might want to add `cursor-pointer` to your tailwind <button> elements

pratik227•1h ago
Noted I will fix it
throwaway290•1h ago
makes it difficult to verify that it runs locally. unobfuscated source is not available. important actions, like open a PDF, save edited PDF, will be stuck or error if you cut the internet after opening the site and only unstuck after you reenable internet. I get it's probably for speed

anyway, if you save the page in Chrome and serve it on a local server, it works even with internet disabled, so there's that.

pratik227•56m ago
Thanks for pointing this out. You’re right - some assets are currently loaded at runtime, which can cause actions to hang if the internet is cut mid-session. All PDF processing itself happens locally in the browser, and as you noticed, serving the page locally works fully offline. Improving offline behavior and making this easier to verify is on the roadmap
Bigpet•1h ago
Was this done heavily LLM assisted? Especially the PDF Edit tools have user-interaction quirks and bugs that a human developer would catch immediately during the regular manual testing when developing.

I'd suggest you at least try and mitigate that by having the LLM do extensive e2e testing if you aren't interested in using your own product.

pratik227•1h ago
It’s still a work in progress. I used an LLM to speed up development, and I’ve done the testing, but I’ll keep improving it no doubt
jacquesm•45m ago
How much of this is LLM derived and how much of it is yours?
Bigpet•32m ago
I don't even care about that. My suggestion to him was earnest. I don't have a problem with LLMs. Just with how people use them. I just don't like "slop". I see the same user-interaction problems every time.

I just don't want people to litter their heavily polished immaculately styled products that have so clearly bad user-interaction design. E2e testing and closing the loop on LLMs does seem to help here.

Though I really would prefer people click around their own product for at least 5 minutes.

jacquesm•15m ago
It matters to me. Depending on the ratio there is a line between 'LLM assisted' and 'LLM derived'. There are enough samples of open source code around this theme out there that this could be one of either and the goal to commercialize it is a messy one if the provenance of the code isn't clear. It would be great to see this sort of thing litigated so that there is at least some clarity rather than just a moral stance.

During my college days, I used iLovePDF a lot, so I wanted to build an alternative to it. It’s not just about PDFs - I also have work in progress around image processing and related tools and Chrome Extetion as well
flexagoon•48m ago
Half of them also have a very obviously vibecoded front-end that looks exactly the same
greggsy•35m ago
They’re created to offer functional outcomes. If they’re doing so in a friendly interface then I’m cool with that
flexagoon•7m ago
Sure, if they're tested well enough that there are no obvious UX issues (which is usually not the case)

It's just that there's zero effort put into them so they don't really offer anything of value. If you write a todo list-tier app, it would be completely useless to most people, but it's a learning project for you. If you vibecoded a todo list-tier app, it's completely useless to most people including yourself.

Due to pdf popularity there is a lot of demand for pdf processing tools. And the format is so complex that there are many nontrivial and creative ways to do pdf processing. That's why these "Hello World" projects usually make Top 5 on HN, and one of the upvotes is usually from me.

I developed an aversion to "with love"-marketing. I've seen too many products come full circle from idealistic "ad-free-forever" "will-never-sell-your-data" "open-source-forever" "customer-first" student-times to selling out everything.

It should be “made for profit, we need to pay mortgage/loan as most of people”… this would be more honest :)

Buy-me-coffee / you can donate / payments in bitcoins accepted / pay as you use / etc.

But I am curious what could work so people wouldn’t be discouraged immediately?

Subscription (monthly/quarterly/annual) is annoying as well…

Adobe has started this wave, I remember it vividly.

NamlchakKhandro•38m ago
All of these are already (and have already been available) for ages on linux
Torwald•34m ago
Good work! I do like that the tools are task centric and that means I don"t have to handle all sorts of things, I just quickly learn the three to four tools that I really need (as a person working in the real world). #pareto

Now, privacy, I love it! That "normal people" just store stuff in the cloud "it's on my phone", yeah ok, is one thing. It's another topic…

But since Gmail came out and was all the rage in nerd circles, I am wondering why the people who understand the tech the most, are so eager to hand over their data to Big Tech and some other very questionable entities.

Here's the thing in terms of money.

If your app does put my data into the cloud, I am not going to use it. At all. Ever.

If your app blesses me with a beautifully designed native GUI (or UI), instead of presenting itself in Electron slop to me, then I am already almost sold. Literally. I start to consider forking over some cash to you, dear developer of that beautifully designed, privacy respecting app.

I do use my browser to browse the web. I am not interested in a "secondary OS architecture" where I have to play sys admin for a range of "apps" aka plugins. Neither Chrome plugins (I don't use Chromium based stuff.) nor Wordpress plugins, nor Emacs "modes" are going to replace well done native programs.

You don't care enough about your project to provide a native program? Tells me, I shouldn't care either. Good buy.

For a high school student who survives on an allowance, paying $39 for an app may be a bit much, but not for an adult with an income.

Curation. A good maintained app store does all the "sys admin" stuff for me. No viruses, no weird installation procedures and so on.

This is why that works. Hassle-free. Locally-run, native app, means beauty and privacy.

I would pay for that. Happily. In fact, I have done so many times. The success of a plethora of developers with paid-for apps in the stores proves I am not the only one.

And, btw, this is the distribution/commerce model that RMS always favoured. I quote RMS:

> Since “free” refers to freedom, not to price, there is no contradiction between selling copies and free software. In fact, the freedom to sell copies is crucial: collections of free software sold on CD-ROMs are important for the community, and selling them is an important way to raise funds for free software development. Therefore, a program that people are not free to include on these collections is not free software.

This is basically the app-store model.

And I would pay, for the above stated reasons and I would be inclined to gulp an even higher price if the package has the "OSS inside" sticker on it. For personal reasons, right?

Then there is one last thing. I don't want to have to create an account somewhere just to test-drive your app. Or to use it fully, later on.

Privacy means, I don't have to be online in order to use the software. The end.

Me and my buddy run a small indie dev studio, and a while back we got frustrated with how most PDF scanner apps feel — clunky UX, subscriptions everywhere, ads, and in some cases your documents get uploaded who-knows-where (for example, incidents reported leaks by TechRadar and Fox News).

So we built our own PDF scanner & editor — lightweight, privacy-first, and (hopefully) not annoying to use. No ads, no subscriptions. Most features are free — a couple of advanced tools require a one-time unlock. All core features run 100% offline with on-device processing.

The main features are built for everyday workflows:

Scan documents — auto edge detect, live corner adjust, batch multi-page Fill and sign forms — reusable signatures, flatten for secure sharing OCR text recognition — preserves layout, searchable PDFs or clean text export (supports 18 languages, e.g., English, Spanish, French, German, Italian, Portuguese, etc.) Edit OCR-detected text — adjust or fix recognised text Page tools — reorder, rotate, duplicate, delete, extract pages Annotations and highlights — comments, text notes, custom watermarks Folder organization — custom folders, drag-and-drop move/rename Everything runs locally — no accounts, no tracking, no upload processing. You can download an AI model to your device (one-time download — it stays cached), and then:

- ask questions about a document - summarise sections or chapters - extract key points or data - turn long documents into quick notes - After the model is installed, all Chat PDF processing happens fully offline on your device.

The app is free to download, and most features are free (scanning, OCR, signatures, annotations, editing, etc).

We wanted to keep the essential tools free, and only charge once for a few advanced features.

We also put together a YouTube playlist with short feature walkthroughs.

You can find the app here: https://apps.apple.com/ro/app/pdf-master-scan-edit-sign/id67...

We’d really appreciate feedback — especially on the Chat PDF feature (usefulness, speed, UX, edge cases, things it should do better). If you try it and have suggestions, we’re actively improving the app based on user feedback.

> make millions

How? Who?

Most of them are freemium, so they're balancing resources funded by subscriptions against the majority free user usage.

And is this local first (as it says on the website) or local only?

bhasinanant•25m ago
I haven't used anything else since I've found PDFGear. Have it installed on all my devices. Still surprised it isn't more known.
asimovDev•23m ago
How does it fare with PDFs consisting entirely of images? Any PDF tool was struggling with compressing a passport scan (made with iPhone so might've contributed somehow, knowing Apple and PDFs) I had to cut down in size. Ended up using ImageMagick cause any Ghostscript based tool couldn't get it below 7 MBs from the original 28MB which, although, pretty good, was still too high and I could tell there was still plenty of detail that could be discarded without losing the eligibility of the document. I had to compress it with ImageMagick at the end, cut it down from 28MB to 3MB.

Also does Adobe have some kind of patent/copyright on PDF forms? I don't think I saw any free tools that can edit fillable fields / tables in PDFs. I don't see any mention of forms in the Suite section of your app either. Is it just stupidly difficult / annoying to implement ?
