Encode or decode text using Base64, Base64URL, URL encoding, HTML entities, Hex, Binary, ROT13, UTF-8, and Unicode escape schemes.
Encode text to Base64 or decode Base64 back to readable text. Supports UTF-8 and ASCII.
Encoders (Base32, Base64→JSON, Hex, SVG→Base64), text tools (character encoding, Unicode converter, Markdown→Slack, PX↔REM), HMAC generator (SHA-1/256/384/512), SVG optimizer, and unit converters (speed, power, pressure). (Base64 encode/decode has its own dedicated page.)
Encode special HTML characters into entities (& < >) or decode them back to readable text.
Strip all HTML tags from content and decode HTML entities. Convert any HTML document back to clean plain text.
Applies five distinct text transformations: reverse entire string order, reverse each word individually, flip upside down using rot180 Unicode, mirror horizontally, and rotate 180 degrees. Perfect for creating puzzles, secret messages, palindromes, and attention-grabbing social media content.
Encoder / Decoder lets you encode or decode text using Base64, Base64URL, URL encoding, HTML entities, Hex, Binary, ROT13, UTF-8, and Unicode escape schemes.. Everything runs inside your browser — nothing is uploaded to a server. It works on any device with a modern web browser.
Encode or decode text using Base64, Base64URL, URL encoding, HTML entities, Hex, Binary, ROT13, UTF-8, and Unicode escape schemes. It's ideal for developers, designers, and anyone who needs to encode or decode text using base64, base64url, url encoding, html entities, hex, binary, rot13, utf-8, and unicode escape schemes 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, Encoder / Decoder 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.
