Encrypt text using AES symmetric encryption with a passphrase. Generate ciphertext that can be safely transmitted or stored.
Decrypt AES-encrypted ciphertext back to plain text using the original passphrase.
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 CSS text-shadow values with interactive preview. Configure offset, blur, color, and opacity.
Audio to Text Transcription converts spoken audio from uploaded files into editable text using browser-based speech APIs.
Encrypts a text note with a passphrase and generates a one-time view link that self-destructs after the recipient reads it.
AES Encrypt lets you encrypt text using AES symmetric encryption with a passphrase. Generate ciphertext that can be safely transmitted or stored.. Everything runs inside your browser — nothing is uploaded to a server. It works on any device with a modern web browser.
Encrypt text using AES symmetric encryption with a passphrase. Generate ciphertext that can be safely transmitted or stored. It's ideal for developers, designers, and anyone who needs to encrypt text using aes symmetric encryption with a passphrase without installing software or sending data to external servers.
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, AES Encrypt 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.

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.
