Need a fast word counter online for an essay, blog post, or social caption? This free Word & Character Counter instantly calculates word count, character count (with and without spaces), and line count as you type. It’s ideal for writers, students, marketers, and anyone who needs to meet a strict character limit for SEO titles, meta descriptions, ads, or social posts. Everything runs locally in your browser, so your text is not uploaded to a server.
How to use: paste your text in the Input panel and watch the live statistics update. For best accuracy, words are counted by whitespace-separated tokens, and lines are detected from newlines.
FAQ: Is this private? Yes — the counting happens on-device. Does it support large text? It works well for typical documents; extremely large pastes may be slower on older phones.
This free case converter online helps you quickly transform text into UPPERCASE, lowercase, Title Case, or Sentence case. It’s perfect for cleaning up headings, fixing inconsistent capitalization, or preparing product titles and filenames. Because it runs entirely in your browser, you can safely format sensitive drafts without uploading them anywhere.
How to use: paste text into the Input box, then tap the conversion buttons. The Output panel updates instantly while preserving your original input, making it easy to compare results and copy the version you want.
FAQ: What is Title Case? It capitalizes the first letter of each word. What is Sentence case? It capitalizes the first letter of the sentence and lowercases the rest (best for quick cleanup).
Use this JSON formatter online free to prettify, minify, and validate JSON in seconds. Whether you’re debugging an API response, cleaning up configuration files, or reviewing logs, a readable JSON structure saves time and prevents mistakes. Our formatter runs locally in your browser, so you can safely paste sensitive JSON without sending it to a server.
How to use: paste JSON into the Input panel. The tool can auto-format as you type, and you can manually click Format to prettify with indentation or Minify to compress JSON for transport. If the syntax is invalid, you’ll see a clear error message.
FAQ: Does this tool change data types? No — it only formats valid JSON. Why am I seeing an error? Common causes are trailing commas, unquoted keys, or single quotes.
Need a reliable base64 encoder decoder online? This tool lets you encode plain text to Base64 or decode Base64 back to readable text. Base64 is commonly used in data URLs, HTTP headers, tokens, and when transferring binary-like data through text systems. We use UTF‑8 encoding for Unicode safety, and everything runs locally for speed and privacy.
How to use: paste your input and click Encode to generate Base64, or click Decode to restore the original text. If the input is not valid Base64, the tool will show a helpful error instead of silently producing wrong output.
FAQ: Is Base64 encryption? No — it’s encoding, not security. Can I decode multiline Base64? Yes, whitespace is ignored during decoding.
This URL encode decode tool helps you safely convert text for use in query strings, paths, and web requests. Encoding
turns spaces and special characters into percent-encoded values (like %20), preventing broken links and malformed requests.
Decoding reverses that process, making URLs readable again for debugging and copy/paste.
How to use: paste text such as Hello world? a=b&c=d, then click Encode or Decode.
The decoder also handles + as spaces (common in form submissions).
FAQ: Should I encode the full URL? Usually you encode components (query values), not the entire URL. Why does “+” appear? Some systems use + for spaces in query strings.
Generate unique identifiers instantly with this random UUID generator v4. UUIDs are widely used as database keys, request IDs, correlation IDs, and public-facing identifiers when you don’t want sequential IDs. This tool generates RFC 4122 version 4 UUIDs using the browser’s secure cryptography APIs when available, with a standards-based fallback.
How to use: choose how many UUIDs you need and click Generate. Copy the output (one UUID per line) into your code, SQL scripts, test data, or documentation.
FAQ: Are UUIDs guaranteed unique? They’re statistically unique for practical purposes. Should I use UUIDs for security? They’re not secrets; use proper auth tokens for security.
Create strong credentials with this secure password generator online. Choose length, include uppercase/lowercase letters, digits, and symbols, then generate random passwords instantly. It’s ideal for setting up new accounts, rotating credentials, or generating temporary passwords for testing. Passwords are generated with browser cryptography and never leave your device.
How to use: set your preferences (length and character sets), click Generate, then use Copy output to copy the password. For best security, use 14–20+ characters and include symbols where allowed.
FAQ: Should I store passwords in notes? Use a reputable password manager. Are symbols always required? Not always, but they improve entropy when allowed.
