Binary Converter

What it does

Free binary converter: text to binary, binary to text, binary to decimal, hex and octal. Instant results, no signup, works offline in your browser.

Type text to see it as binary, or paste binary to read it back as text (ASCII). Conversions run on your device as you type, so results are instant and your text stays yours. Convert binary to decimal, decimal to binary, hexadecimal to binary and octal — in any direction. Type a number in any field and the other three update as you type. See the dedicated hex converter below. Hexadecimal (base 16) uses the digits 0–9 and A–F, and each hex digit stands for exactly four binary bits. Convert hex to binary, hex to decimal and hex to text — every conversion runs in your browser as you type. Every hex digit maps to a 4-bit group, so A is 1010 and F is 1111. Type a hex value in the binary, decimal…from binaryconverter.net

  Talanoa▲343

  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…
