OpenTool is a collection of 294 free, browser-based tools covering PDFs, images, conversions, unit/currency conversion, finance, math, developer utilities, typing tests and India government exam prep. What makes it different: almost every tool runs 100% on your device — your files and inputs never get uploaded. No account, no installs, no watermarks. From compressing a PDF to resizing a photo for SSC/IBPS/JEE/NEET forms, it works on phone or desktop in seconds. Perfect for studnet.
Free online tools for PDFs, images, conversions, calculations and more. Fast browser-based utilities with no signup for everyday tasks.
Twenty-odd categories of handy tools — PDFs, images, calculators, converters and more. No account to make, no file uploads for most of it, and nothing to install. It's simple: we don't want your files. Most tools do everything on your device, so nothing ever gets sent anywhere. A few do need a server — the document converters (PDF↔Word, PDF↔Excel, Excel/Word/PowerPoint→PDF, PDF→PPT) — and those erase your file the moment the job finishes. OpenTool is a free collection of 264 + browser-based utilities for everyday tasks — no account, no email, no watermarks and no usage limits. Everything runs in the tools section of this site, organised into categories like PDF Tools , Image Tools , file…from opentool.tech

Talanoa▲341Hi 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…

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…

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…
