Category directory
Start with one of the 10 stable ZZP Box top-level categories, then open the focused category page for your task.
Text and writing tools help you measure, clean, compare, analyze, and prepare everyday text. This category groups writing counters, cleanup helpers, case conversion, list tools, readability checks, Markdown and HTML text helpers, and generators without turning the page into a flat link dump.
Developer and data tools are organized around common implementation tasks: format structured data, encode and decode values, inspect tokens, test regex patterns, format or minify code, and prepare database or API-friendly output while keeping tool pages focused.
SEO and marketing tools are grouped by practical publishing workflows: metadata drafting, search result previews, UTM and campaign URLs, Open Graph cards, crawling and sitemap helpers, international SEO, social copy, and link cleanup.
Calculators and converters bring everyday math, unit conversion, proportion checks, business pricing, discounts, marketing cost metrics, freelance rates, billing estimates, and break-even planning into one scalable category.
Date and time tools support scheduling, planning, timestamp conversion, timezone comparison, workday counts, date ranges, week numbers, countdowns, deadlines, and calendar-style helper tasks from one structured category.
Design and CSS tools are arranged for frontend production work: color conversion, contrast checks, responsive sizing, CSS units, layout generators, visual effects, typography helpers, SVG and frontend assets, and accessibility support.
Image, PDF and file tools provide a stable home for current file-adjacent utilities and future browser-based file workflows such as image sizing, format conversion, metadata checks, PDF helpers, QR codes, CSV cleanup, spreadsheet previews, and local file utilities.
Web and network tools organize browser-facing diagnostics and website checks in one place: URL analysis, device information, page checks, HTTP and header helpers, DNS and IP lookups, connection quality, and performance-oriented utilities as the catalog grows.
Privacy and security tools are kept separate from exaggerated safety promises. This category covers password generation, local privacy utilities, metadata cleanup, token and key helpers, hashing and verification, and practical security checks with clear page-level boundaries.
Random, learning and everyday tools collect lightweight helpers for quick choices, random values, team grouping, dice and coin simulations, classroom calculations, reading checks, study-friendly tasks, and small daily utilities.
