Explore the Complete Simple-Toolz Collection
Browse the full Simple-Toolz collection: unit converters, text tools, code formatters, crypto tools, random generators, and web utilities in one place.
February 10, 2026
Developers juggle dozens of small tasks every day: converting a timestamp, formatting a JSON payload, generating a UUID, or checking an HTTP status code. Instead of searching for a different website each time, Simple-Toolz puts every utility you need in a single, well-organized collection. Let us walk through everything that is available.
How the Tools Are Organized
The Simple-Toolz collection is divided into logical categories. Each category groups related utilities together so you can jump straight to the right tool without guessing where it might be. The main navigation makes it easy to switch between categories, and every tool page links to related tools so you can discover new ones naturally.
Unit Converters
Need to convert miles to kilometers, Fahrenheit to Celsius, or pounds to kilograms? The unit converter section supports six measurement categories: length, weight, speed, temperature, volume, and area. Each converter provides real-time results, a swap button for quick reversals, and a quick-reference information panel that explains the relationship between units.
Text Tools
The text tools section is packed with utilities for manipulating and analyzing text. You will find counters for words, characters, lines, sentences, and paragraphs, each with reading-time estimates. Text transformers handle uppercase, lowercase, title case, camelCase, snake_case, reversal, line-break removal, duplicate removal, and repetition. These tools are invaluable for content writers, copywriters, and developers preparing strings for processing.
Code Formatters and Minifiers
Messy code is hard to read and debug. The code formatting tools support JSON, JavaScript, TypeScript, CSS, HTML, YAML, GraphQL, Markdown, and SQL. Paste your code and it is instantly beautified using Prettier under the hood. On the other side, the minifier tools compress JSON, CSS, HTML, JavaScript, and SQL, showing you the original size, minified size, and percentage savings. Both formatters and minifiers auto-process with a short debounce so results appear as you type.
Cryptographic Tools
Security-related tasks come up often in development. The crypto section provides hashing with MD5, SHA-1, SHA-256, and SHA-512. You can encrypt and decrypt text with AES, generate bcrypt hashes with configurable salt rounds, evaluate password strength with detailed feedback, create RSA key pairs, work with JSON Web Tokens, and generate UUIDs and ULIDs. Every cryptographic operation runs entirely in the browser, so your sensitive data stays on your machine.
Random Generators
From testing to creative brainstorming, random data is surprisingly useful. Simple-Toolz offers generators for random numbers with customizable ranges, random strings and passwords with character-set controls, random colors with hex previews, random names, letters, words, yes/no decisions, coin flips, and dice rolls with configurable dice types from D4 to D100. Batch generation is supported so you can produce multiple results at once.
Web Utilities
The web utilities section covers the tasks that web developers encounter most frequently. You can encode and decode URLs, parse query strings, generate Basic Auth headers, look up HTTP status codes, compare JSON documents side by side, decode JWTs, detect device information, parse user agent strings, slugify text, and handle HTML entities. Each tool is focused on doing one thing well, with clear inputs and immediate outputs.
Development Tools
Rounding out the collection are utilities aimed at day-to-day development tasks: a Unix timestamp converter for translating between epoch time and human-readable dates, a cron expression builder that both constructs and explains cron schedules, and a Git cheatsheet for quick command reference. These tools save you from context-switching to documentation or running local scripts.
Everything in One Place
The greatest advantage of Simple-Toolz is consolidation. Rather than maintaining a sprawling collection of bookmarks, you have a single destination for all the small utilities that keep your workday moving. Every tool is free, runs client-side for privacy, and works without an account. Explore the collection, find the tools you use most, and make Simple-Toolz a part of your daily routine.
