About BrowserTools
BrowserTools is a curated collection of small, focused web tools, converters, validators, encoders, calculators and networking utilities, built around a single principle: your data is yours.
Our mission
Most of the everyday utilities people search for online ship as bloated SaaS products that demand a signup, upload your files to remote servers, or bury the result behind layers of tracking and ads. We believe these tools should be the opposite: fast, private and out of the way.
Whenever a task can be done locally, and most can, it runs entirely in your browser. Files never leave your device, no account is required, and there is nothing to install. The few tools that truly need a server (DNS, ping, WHOIS) call a minimal backend that does only what is asked and logs nothing identifiable.
How it stays free
The site is supported by a minimum of unobtrusive advertising. No interstitials, no pop-ups, no autoplay video, no tracking pixels beyond what the ad provider strictly requires. If we ever can't keep ads minimal and respectful, we'll find another way before degrading the experience.
What you get
- Privacy by default, local-first computation, no signup, no profile.
- No upload unless necessary, when a tool can run in your browser, it does.
- No dark patterns, no cookie walls beyond what the law requires, no email harvesting.
- Open in spirit, every tool is a small, auditable module focused on one job.
Who runs this
BrowserTools is built and maintained by The BrowserTools Team, and has been running since 2026. Each tool is written and reviewed by hand: we test it against real inputs, document what it does, and note the cases where a format or technique can trip people up. When we get something wrong, we fix the tool and the page.
