Small browser utilities are useful when you need a quick answer without opening a full IDE, installing a package, or pasting data into a heavyweight service.

UTools focuses on everyday developer tasks: formatting JSON, encoding Base64, generating UUIDs, converting timestamps, and preparing URL-safe strings.

When online tools are useful

Use online utilities for quick local checks, throwaway test data, and formatting snippets that do not contain secrets.

For sensitive credentials, customer data, or production payloads, prefer local scripts or trusted internal tooling.

Core utilities

• JSON Viewer for formatting, validating, and minifying JSON.
• Base64 Tools for encoding and decoding text.
• UUID Generator for test IDs and fixture data.
• Time Converter for Unix timestamps and date checks.
• URI Encode / Decode for query strings and URL components.

Practical workflow

Start with the tool that matches the data shape, paste a small sample, copy the cleaned output, and keep moving. The goal is to reduce friction for common development tasks without changing your project setup.
