Developer Tools
Toolzoid provides a growing suite of free browser-based utility tools used daily by developers, content writers, SEO professionals, and marketers. Our most popular developer tool is the JSON to CSV converter — paste any JSON array and instantly get a clean, downloadable CSV file with correct headers, flattened nested objects, and your choice of comma, semicolon, tab, or pipe delimiter. It works for Excel imports, Google Sheets imports, and any data pipeline workflow.
Our Base64 encoder and decoder handles text encoding, file-to-data-URI conversion, and decoding of JWT tokens and API credentials in three modes. The Base64 encode/decode tool runs entirely client-side — your data never touches a server. Developers also rely on our .htaccess file generator to create Apache configuration for shared hosting — supporting Force HTTPS redirects, Gzip compression, browser caching rules, hotlink protection, and directory indexing prevention. The .htaccess generator for cPanel is the fastest way to configure Bluehost, Hostgator, SiteGround, and GoDaddy hosting environments.
For design and development workflows, the lorem ipsum placeholder text generator produces Classic Latin, Hipster, Corporate, or Tech Startup flavored text by word, sentence, or paragraph count — with optional HTML <p> tag wrapping. The free lorem ipsum generator is used by web designers, UI developers, and content agencies daily.
Writing & Content Tools
Our word counter tool is built specifically for bloggers, SEO writers, and students. It delivers real-time word count, character count (with and without spaces), sentence count, paragraph count, estimated reading time, speaking time, and a live keyword density table showing the top 10 most-used meaningful words with frequency percentages. Whether you need a word counter for essays and college papers or a word counter optimized for SEO content writing, the tool works the same — paste and go. The online character counter is also useful for Twitter/X (280 char limit), meta descriptions (160 chars), and SMS messages (160 chars).
The text formatter includes 17 transforms covering every case convention: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, alternating case, and reverse. The uppercase to lowercase converter and camelCase converter are the most searched variants. It also cleans up text — strip extra whitespace, remove duplicate lines, remove empty lines, sort alphabetically, and remove punctuation.
SEO & Marketing Tools
The URL slug generator converts any blog post title, product name, or phrase into a clean, SEO-optimized permalink. It automatically removes stop words (the, a, of, for, and…), handles accented characters (é → e, ñ → n), enforces lowercase, replaces spaces with hyphens, and limits length to under 60 characters for optimal SEO. It's the go-to tool for WordPress permalink generation and for building an SEO-friendly URL structure on any platform. The bulk conversion feature lets you paste 50+ titles and get all slugs at once.
Marketers running Google Analytics campaigns rely on our UTM link builder to construct properly formatted tracking URLs with utm_source, utm_medium, utm_campaign, utm_term, and utm_content parameters. The UTM campaign URL builder validates your base URL, auto-lowercases parameter values, provides quick-fill presets for common sources (google, facebook, newsletter, linkedin) and mediums (cpc, email, social, display), and saves your last 10 URLs for quick access.
Before sharing any page on social media, use the Open Graph tag previewer to see exactly how your page renders as a link card on Facebook, LinkedIn, Twitter/X, and WhatsApp. The OG meta tag generator produces complete, copy-ready <meta> tag code covering og:title, og:description, og:image, og:type, og:url, og:site_name, plus all Twitter Card tags. The OG checklist tracks which tags are missing so nothing gets overlooked before launch.
AI & Productivity Tools
The AI prompt optimizer helps users of ChatGPT, Claude, and Gemini write dramatically better prompts using the RCTFE framework: Role, Context, Task, Format, and Examples. The ChatGPT prompt generator includes pre-built templates for blog writing, cold email, and code generation — each structured to produce outputs that are specific, well-formatted, and on-target. A live token estimator prevents prompts from exceeding context window limits.
The password generator uses
window.crypto.getRandomValues()
— the Web Cryptography API — to generate truly unpredictable passwords. Choose length
from 8 to 128 characters, include or exclude uppercase, lowercase, numbers, symbols,
and ambiguous characters. The live entropy display and crack-time estimator (at 1 trillion
guesses/second) give you objective confidence in your password strength. Try the
strong password generator or the
random password generator — both are free with no account required.
