About UtilDaily

Last updated: February 2026

UtilDaily was built out of a simple frustration: developer tools online tend to have one of two problems — they are either bloated with features you do not need, or they upload your data to a remote server just to run a basic operation like formatting a JSON string. We wanted tools that are focused, fast, and private.

We started with a handful of tools we use ourselves: a JSON formatter that works offline, a Base64 encoder that does not log your payloads, a UUID generator that uses real cryptographic randomness. Each tool does one thing and does it well.

Our Mission

We believe everyday tools should be fast, free, and private. No sign-up required, no subscription, no ads that track you. Just tools that work — instantly, in any browser, even offline once the page has loaded.

How the Tools Work

Every tool on UtilDaily runs entirely in your browser. No data is ever sent to our servers — because we do not have servers that process your input. The stack is intentionally minimal and relies on standard browser APIs:

  • JSON formatting — uses the browser's native JSON.parse() and JSON.stringify()
  • Hash generation — uses the Web Crypto API (crypto.subtle.digest()), the same API your browser uses for TLS
  • UUID generation — uses crypto.randomUUID(), which provides cryptographically strong randomness per RFC 4122
  • Base64 encoding — uses atob() and btoa(), the standard browser encoding functions per RFC 4648
  • URL encoding — uses encodeURIComponent() per RFC 3986

These are the same APIs trusted by every major browser and used in production by millions of applications. We do not reimplement them — we expose them as clean, focused tools with a usable interface.

Privacy by Design

The privacy model is simple: there is nothing to collect. There is no database, no user accounts, no session tracking, and no analytics that identify you. UtilDaily uses Google AdSense to cover hosting costs; these ads are served by Google according to their privacy policy, but no data from your tool input is ever shared with anyone.

We take this seriously because developers frequently need to process sensitive data — API responses, authentication tokens, configuration files, personal records. You should be able to format a JSON payload or decode a Base64 string containing real user data without wondering who else might be reading it.

Available Tools

UtilDaily currently offers 18 free tools across six categories:

New tools are added regularly. If there is a small utility you find yourself rebuilding from scratch or pasting sensitive data into an untrusted site to accomplish, we would love to hear about it.
