Why Use Toolisk Tools?
Most online utilities are slow, ad-heavy, or upload your data to a server. Toolisk Tools are different. Every utility is built as a single-page app, runs entirely in your browser, and works without sign-ups. Whether you are formatting JSON during an API debug session, encoding a URL for a query string, or counting words for an SEO description, you get instant results without leaving the page.
Each tool is built with a focus on the small details — keyboard shortcuts, copy-to-clipboard buttons, sample data, and clean error messages. These are the kind of utilities you bookmark and open ten times a day.
What You Can Do with Each Tool
URL Encoder / Decoder — Safe URLs in One Click
Convert special characters into percent-encoded URL components. Useful for query strings, REST APIs, and OAuth flows where you need to pass spaces, ampersands, or unicode safely.
JSON Viewer & Formatter — Read Any API Response
Paste raw JSON to get a readable, syntax-highlighted view with collapsible nodes. Format, minify, validate, and copy back the cleaned-up output. Catches syntax errors with line numbers.
Word Counter — Track Length and Reading Time
Count words, characters (with and without spaces), sentences, paragraphs, and estimated reading time. Includes Twitter, SEO meta description, and Open Graph length indicators.
Base64 Encoder / Decoder — Standard and URL-Safe
Convert text to Base64 and back, with full UTF-8 support and URL-safe variants. Useful for email attachments, data URLs, JWTs, and config files where binary data must travel as text.
Color Converter — HEX, RGB, HSL, CMYK
Convert between every common color model with a live preview swatch. Includes contrast ratio calculator for WCAG accessibility checks and tint/shade variations for design palettes.
Hash Generator — MD5, SHA-1, SHA-256, SHA-512
Generate cryptographic hashes from any text input. All hashing happens locally using the Web Crypto API — your input is never transmitted. Useful for checksums, fingerprints, and password verification flows.
Regex Tester — Live Match Highlighting
Build and test regular expressions with real-time match highlighting, capture group breakdowns, and flag support. Quick reference cheatsheet covers metacharacters, quantifiers, and groups.
Case Converter — All Common Formats
Convert text between camelCase, snake_case, kebab-case, PascalCase, CONSTANT_CASE, Title Case, and Sentence case. Essential for renaming variables, generating slugs, and cleaning up exported data.
Built for Speed and Privacy
Every Toolisk Tool is a static page with zero server-side processing. The page loads, the tool runs, and your input never leaves your machine. This means: no telemetry on your data, no ads injected into your output, and no rate limits.
You can paste credentials, API keys, secret JSON payloads, or sensitive text into any of these tools without worrying about server-side logging. They are designed exactly the way you would build them for yourself.
