Show HN: I built 184 free browser tools – PDF, image, dev, AI tasks, no upload

Built this because I kept finding tools that upload your files to a server. Every tool here runs entirely in your browser — PDF merge, JWT decode, image crop, LLM token counter, etc. Client-side by architecture, not by promise. Happy to answer questions about how any of the tools work

Whenever I see "pro" in a domain name, there's usually a subscription or upgrade waiting for me at the other end, or something I have to sign up for. Nice to see that your site isn't one of those. Thanks for the free tools, man. Your Privacy-Proof page is also reassuring. I would make it more prominent, but that's just me. It is great that it is there in the first place. Honesty always. Two questions: - Do you have a GitHub repo for this? - Also: What made you decide on that `.pro` domain? Just curious.

Could you share GitHub? Also image background remover doesn't seem to work on my PC (macOS 26.5.1, chrome 149.0.7827.103)

Allow me to suggest a form where people can leave their email to get updates or a newsletter from you! Brevio is the kind of thing that a lot of people look for, and value. The fact you're not charging and it all runs locally earns you a lot of trust and goodwill. I'm not suggesting monetising your audience or starting a substack, but you never know when having a list of people who are interested in the things you build could come in handy. I wouldn't even think you'd need to send a confirmation email: just leave it there and see who fills it in.

Actually, I use Raycast on macOS for easier use; it would be great if you could add this as a plugin there.

I am amazed and impressed, but someone should point out here some of the gaps in vision and effort or craft that lead to manual spam like “How to Compress Images Without Uploading Them (2026)”

Unbelievably cool, keep it up!

More vibe coded AI slop?

Why mess with scrolling?

PUSH_AX

Please remove the scroll jacking, there is just no need.

Neat. Where can I submit feedback? Cargo.lock shouldn’t be in gitignore :)

Normalize not writing "I built" for vibecoded sites with generic Claude UI.

Is there an way for me as user to be sure that the no upload promise holds? I mean yeah I could use the dev tools, but it would be cooler to have the browser eg prohibiting visually any upload of data beyond the pure url request

Thanks for making these, and sorry that Hacker News has so much of the “thanks I hate it” crowd. It’s a good thing you’re doing - especially to provide them without monetizing. Though one could generate these tools themselves if needed, the generated tools won’t be as refined as you’ve codified here and won’t be immediately available for use - they have to be generated! The website is great and functional but if I may, it needs some tweaks so it matches the offer. Since the offering’s about doing less (no login, no upload) you’d be better to go with “less is more” on the feel, and only use animations - or interfere with scrolling - if such things truly add extra information. All the animations there now are decoration. The tools have no such decoration, and that causes dissonance. Gonna be bookmarking this while wishing for a search engine that finds stuff like this instead of its SEOed out the wazoo compatriots. But maybe there’ll always be value in human curation.

cool stuff! How much traffic do they generate / how long did it take to get to it?

The first tool I tried, Background Remover, I can't even upload the image. AI coded slop
