Generate RSA, ECDSA, and Ed25519 SSH key pairs with proper OpenSSH format output. RSA uses RSASSA-PKCS1-v1_5 (2048-bit). ECDSA supports P-256 and P-384. Ed25519 uses a pure-JS implementation (no server). Public keys paste directly into ~/.ssh/authorized_keys. Everything runs locally in your browser — nothing is uploaded.
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.
Generate JSON Web Keys (JWK) with RSA key sizes of 2048 or 4096 bits. Export public and private keys in JWK format.
Scan text and code for leaked secrets and credentials. Detects Stripe keys, GitHub tokens, Slack tokens, Google API keys, AWS keys, OpenAI keys, JWT tokens, private keys, and config passwords.
Generates RSA (2048/4096) or ECDSA (Curve25519) PGP key pairs with customizable user IDs, expiration dates, and passphrase protection.
Extracts all text content from PDF files and converts it to clean Markdown format with proper headings, lists, and structure. Perfect for documentation, research papers, and text extraction.
SSH Key Generator lets you generate RSA, ECDSA, and Ed25519 SSH key pairs with proper OpenSSH format output. RSA uses RSASSA-PKCS1-v1_5 (2048-bit). ECDSA supports P-256 and P-384. Ed25519 uses a pure-JS implementation (no server). Public keys paste directly into ~/.ssh/authorized_keys. Everything runs locally in your browser — nothing is uploaded.. It works on any device with a modern web browser.

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, SSH Key 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.
