All Categories
Browse all tool categories available on MinimalDev. This page is the main starting point if you want to explore the site by task type instead of opening one tool directly.
Each category groups together tools with a similar purpose, such as conversions, calculations, formatting, generation, or image processing. If you are not sure which exact tool you need yet, starting from a category is usually the fastest way to find it.
How to use this page
Choose the category that best matches your task first. For example, use Converters for unit changes, Math for percentages and formulas, Finance for money-related estimates, and Developer Tools for validation, formatting, and encoding tasks.
If you already know the tool name or only remember part of it, use the search box below to narrow the visible category cards more quickly.

OpenCategory overview
Converters
Best for switching values between units such as distance, weight, temperature, area, volume, time, and data size.
Math
Best for percentages, number relationships, formulas, and other general calculation tasks used in school, work, and daily life.
Finance
Best for payment planning, interest estimates, savings calculations, salary breakdowns, and basic budgeting tasks.
Date & Time

Utilities
Best for general-purpose helpers that do not fit one narrow subject area, including generators, counters, and quick tools.
Developer Tools
Best for programmers and technical users who need validators, parsers, encoders, decoders, and formatting helpers.
Text Tools
Best for cleaning, transforming, counting, comparing, or analyzing text content for writing and editing workflows.
Generators
Best for creating names, IDs, placeholders, slugs, passwords, random values, and other generated content.
Image Tools
Best for browser-based image resizing, conversion, cropping, compression, and other practical image editing tasks.
Design Tools
Best for visual helper tasks such as colors, gradients, spacing, sizing, and other design-related utilities.
Why categories matter
Category pages are useful because many visitors know the kind of task they need to complete, but not always the exact tool name. Organizing tools by subject makes the site easier to explore and reduces the time needed to find the right page.
This also helps separate different workflows. A visitor looking for a loan estimate, for example, should not have to sift through text utilities or developer encoders to find the correct page.
