Bitwise Calculator - Bitwise calculator — AND, OR, XOR, NOT & shifts with steps

by•
Pure bitwise calculator for developers — AND, OR, XOR, NOT, left/right shifts. Enter binary, decimal, or hex; see results in all four bases plus 32-bit bit visualization. Calculation history, one-click examples, "Why This Matters" explanations. 100% client-side, no signup, no tracking. Built after a 2 AM debugging session where every existing tool was either ad-infested or hid the bit-level detail.

Hey PH 👋 This tool exists because of a 2 AM debugging session that broke me. I was working on a project that involved parsing a custom binary protocol — header flage. My code wasproducing wrong output and I needed to trace through the bit manipulation by hand. tor" — the top resultswere ad-heavy sites with newsletter popups and "Pro" subscriptions. Oworked but only showeded up using pen andpaper at 2 AM like it's 1995. So I spent a weekend building this. Clean, dark-themed, no BS. Enter numbers, pick an opera base plus bit-by-bitvisualization. Everything in your browser — no data leaves your machine, no signup. The feedback that hit it to teach hisstudents because the bit visualization makes it click instantly. That's the whole reason I bui Try it, break it, tell Leo

The bit visualization is genuinely the standout feature here, love that it finally shows the actual bits flipping. One thing that would make this my daily go-to: a quick bitmask helper where I type something like "flag with bits 3 and 7 set" and it spits out the hex value, since I do that constantly when registering devices and always end up doing the math by hand.
