About UtilDaily

UtilDaily is a suite of free, privacy-first utility tools built for developers, designers, and everyday users.

Why We Built This

Most online tools send your data to a server, display intrusive ads, or require you to create an account before you can do anything. We wanted something different — a set of tools that respect your time and your privacy. UtilDaily was built to solve that problem: every tool runs entirely in your browser, loads instantly, and works without any sign-up.

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.

Technical Philosophy

  • ✓All processing happens in your browser — computations run in JavaScript on your device. Nothing is sent to a remote server.
  • ✓Standards-compliant cryptography — hashing and encoding tools use the Web Crypto API, following the relevant RFCs.
  • ✓Static export — no server, no database — the site is pre-rendered at build time. There is no Node.js server and no server-side processing.
  • ✓Verifiable — open your browser's DevTools, check the Network tab, and confirm that no data leaves the page while you use any tool.

Privacy Commitment

Developers frequently need to process sensitive data — API responses, authentication tokens, configuration files. You should be able to format a JSON payload or decode a Base64 string without wondering who else might be reading it.

  • No account required — ever.
  • No data is sent to any server during tool use.
  • No tracking beyond anonymous, privacy-respecting analytics.
  • Most tools work offline after your first visit.

The Tools

UtilDaily currently offers 40+ free tools across developer utilities, text processing, encoders and decoders, calculators, generators, and more. Every tool is designed for real workflows — whether you are formatting JSON, generating UUIDs, encoding Base64, calculating dates, or converting data formats.

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. Browse all tools.

Who is behind UtilDaily?

UtilDaily is built and edited by the UtilDaily Team — developers and writers based at 22Lab. Every guide is researched against primary sources (NIST, IRS, MDN, peer-reviewed journals) and reviewed by at least two team members before publication. Read about our editorial process →
