OnlineToolkitHub

What it does

It's a single hub of 200+ browser-based tools — PDF converters, image compressors, unit and currency converters, text and JSON formatters, calculators, generators, and more — and every one works the same way: no signup, no email wall, no credit card, no "sign in to download." You open a tool, use it, get your result. That's the whole flow.

OnlineToolkitHub is a free online tools platform for PDF, image, developer, text, SEO, calculator and AI tools — every tool you need, all in one place.

Powerful, easy-to-use, and 100% free online tools for PDFs, images, developers and everyday calculations — no sign-up required. OnlineToolkitHub started from a familiar annoyance: needing a quick PDF merge or an image resize and landing on a page buried in pop-ups, fake countdown timers and a sign-up wall before you could actually use anything. We built this instead — 225 + free tools for PDFs, images, developers, text, SEO, calculators and AI, ready the moment you open them, no strings attached. It's grown past just tools. The blog breaks down real engineering decisions we've made — Aurora vs RDS, Redis vs Memcached and the rest — and the Learning section collects genuine interview…from onlinetoolkithub.com

  Talanoa▲341

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
