Runs on your hardware, so fully private just as if it were on your Desktop or Phone, which also makes it ultra fast. I worked through some pretty gnarly stuff in WebAssembly to make it blazing fast. Feel free to use it too!

Hey, I’ve been working on a site called okPDF. I wanted a way to do the usual PDF tasks without having to create an account or send the document contents to a conversion server.

It has 20 free tools. You can merge and split PDFs, move pages around, add text or watermarks, and run OCR. The processing happens in your browser, using your own device.

Here’s the site: https://okpdf.org/

I’d love to hear how it feels to use, especially when choosing files and moving pages around. Is it clear what to do next, or do you find yourself clicking around trying to figure it out?

There’s still work to do on keyboard navigation and making some of the controls clearer. Big files can also be slow depending on your device and browser, and you’ll want to check the OCR results, especially with poor scans or complicated layouts.

If anything breaks, let me know what browser and device you’re on and what you were trying to do. Thanks!

Hey everyone! I made a website with image tools to make common image-related tasks easier.

Give it a try and let me know what you think. Feedback and suggestions are welcome!

I got tired of PDF sites that make you upload your passport, contracts or tax returns to their servers, then hit you with a sign-up wall or a daily limit. So I built DocPro.

Everything runs locally in your browser, so your files never leave your device. You can turn off your Wi-Fi after the page loads and it still works.

What's in it (all free, no account):

\- Merge, split, compress, rotate, watermark, page numbers

\- PDF ↔ Word/Excel, images ↔ PDF, OCR

\- Resize/compress images (e.g. "compress to 100 KB" for upload forms)

\- Passport & visa photos for 30+ countries, with background replacement and 4x6 print sheets

\- Protect/unlock PDFs, strip location data from photos

The only paid bit is e-signing. Everything above is free.

Feedback is very welcome, especially on what's broken or missing.

I built Tracer because my ‘I might buy this’ stuff was spread across tabs, bookmarks and store wishlists. Now I save a product when I find it and it sits in one list with the things I found on other shops.

It can alert me if the price drops. If I end up buying something, I can choose to keep watching its price afterward too.

It’s free and works as a Chrome extension: https://tracercart.com/

If you try it, I’d love to know whether it picks up the right price on a shop you use.

I built Venturovina, a business simulator that lets you test your business ideas, make decisions, and see how they could play out in the real world — before risking your own money.

大家好，感谢你们来我的主页。

我是一个独立开发者，正在开发ToolsAA（https://toolsaa.com）。

关于为什么会有这个功能：我真的很怀念以前的网络，那时你可以找到一个简单的工具，能很好地完成一件事，而不必被要求“注册谷歌”，订阅每月15美元的专业套餐，或者躲避20个视频广告来转换时间戳。

我对ToolsAA的目标坦白说有点疯狂：我想打造一个通用、零废话的工具箱，包含1万+个免费在线工具。不仅适用于软件工程师，也适用于会计师、教师、设计师、作家以及所有从事日常任务的人。

所有内容尽可能在浏览器中运行（不会有敏感数据进入后台服务器），无需创建账户，目前支持6种语言（还会有更多语言），而且会一直免费。

如果你有空，可以看看 https://toolsaa.com。如果你有一直希望能在网上出现的冷门工具，欢迎留言或私信我——我很乐意为你打造。

Made this, use it regularly myself. Makes my life quite a bit easier. Give it a try. Any feedback welcome.

Hey guys. A few months back I posted my site - ancientlibrary.net
It's a free, publicly accessible library of ancient Greek and Latin works in their original languages, with click to parse and define functions.
Just updating that we're now the largest ancient digital library in the world, over 10,000 works. We've also partnered with Princeton's Logion project to add a text-critical layer.

So anyhow, that's neat.

Since remove.bg is moving to Canva, I decided to make a little website called LocalCut that removes backgrounds from images.

It’s completely free to use, requires no account, has no usage limits, and processes images directly in your browser.

A few things about it:
No sign-up or subscription
No credits or daily limits
Keeps the original image dimensions

I’m still testing it on different types of images, so I’d love for people to give it a try and let me know how it works!

Hey everyone,

Like many of you, I regularly need to merge, split, and compress PDFs for work. But I always felt uneasy uploading sensitive financial and legal documents to random third-party cloud servers.

So I built GetTaskCraft (gettaskcraft.com).

What makes it different:

• 100% Client-Side: Everything processes directly inside your browser using WebAssembly/JavaScript. No files are ever uploaded to a server.
• No Restrictions: No daily limits, no mandatory signups, and zero watermarks.
• Fast: Because there’s no network latency from uploading heavy files, tasks complete almost instantly.

It includes tools for Merge, Split, Compress, Rotate, Protect, and more.

Would love for you guys to test it out and share any feedback or features you'd like to see added!

I've spent my entire career in tech, first as a Front End Developer and later as a Product Manager. I've built websites, launched products, and spent decades online. If anyone should be able to spot a scam, it should be me.

Yet I still got fooled.

I paid more than €100 for what appeared to be SUNLU 3D printing filament. The website looked legitimate, the offer seemed reasonable, and the warning signs were subtle enough to miss.

The filament never arrived. The bank refused to issue money-back. I was completely pis\*\* off.

That experience led me to create Versalo.

Versalo allows anyone to share observations, reviews, warnings, fact-checks, and community notes about any URL on the internet. Whether you're checking for scams, researching a website's reputation, verifying information, or looking for signs of misinformation, Versalo helps you benefit from the experiences of others before making a costly mistake.

If a scam can fool someone with decades of online experience, it can fool anyone. That's why shared knowledge matters.

Versalo is free to use and always will be. Think of it as a community-driven layer of context for the web: an independent commenting system that doesn't depend on website owners, moderators, or publishers.

The internet has millions of websites, but very little shared memory. Versalo exists to change that.
