Generate RSA key pairs (2048/4096-bit) using the Web Crypto API. Export public and private keys as PEM strings. All client-side, no server uploads.
Compute SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA-3, and RIPEMD-160 hashes, generate HMACs, and encrypt/decrypt text with AES. All client-side, no server uploads.
Generate secure API keys with configurable length, character set, and optional prefix. Use with any authentication scheme.
Hash API keys using SHA-256 for secure storage. Never store raw API keys — hash them before persisting to your database.
Reduces JPG, PNG, and WebP file sizes using smart compression with a side-by-side quality preview slider. Balance file size and visual quality visually — max 20MB per image. Perfect for web optimization, email attachments, and social media uploads.
Generates RSA (2048/4096) or ECDSA (Curve25519) PGP key pairs with customizable user IDs, expiration dates, and passphrase protection.

Direct text entry, file upload, or URL-based input — depending on the tool. Paste or type your content directly into the provided editor area.
Yes. After the initial page load, RSA Key Pair Generator runs entirely on your device with no internet connection needed. All processing is done locally.
Tools cover JavaScript, CSS, HTML, SQL, Python, JSON, XML, CSV, and more. Check individual tool descriptions for specifics.
No. All code processing — formatting, minification, conversion, hashing — runs locally in your browser.
Yes. Since processing is local, performance depends on your device. Most operations handle large files without issue.
Yes. SQL uses sql-formatter, JSON uses native JSON.parse, and other formatters follow widely adopted formatting rules.
Yes. All developer tools work fully offline after the initial page load.
Time Converter
Convert between time units including seconds, minutes, hours, days, weeks, months, and years with precise decimal results.
Diff Checker
Compares two input texts side-by-side, highlighting inserted, deleted, and changed lines with distinct background colors.
Regex Tester
Provides an interactive environment where users can write a regular expression pattern, test it against sample strings, and view real-time match.
JSON Formatter
Pretty-prints raw JSON with configurable indent width, key sorting, and bracket collapsing options while flagging syntax errors with exact.
JS Minifier
Strips comments, whitespace, and shortens local variable names in JavaScript source without altering execution semantics.
Base64 Encode/Decode
Encodes text or small files into Base64 strings and decodes them back with automatic MIME-type detection for binary safety.
