Small, practical browser utilities for timestamps, encoded text, random strings, URL slugs, social previews, favicon files, and quick totals from messy copied lists.
Paste a timestamp in seconds, milliseconds, microseconds, or nanoseconds, convert dates back to epoch values, and copy common UTC, local, ISO, and RFC formats.
Convert Your TimePaste plain text to create Base64, decode Base64 back into readable UTF-8 text, copy the result, and compare character and byte counts in the browser.
Convert Base64Enter a regex pattern, paste test text, toggle flags, and inspect highlighted matches, start positions, lengths, and capture groups without uploading your text.
Test Your RegexPaste spreadsheet exports, database rows, or comma-separated data, handle quoted values, and generate pretty or minified JSON without sending the data anywhere.
Convert CSV to JSONAdd source, medium, campaign, term, and content parameters to a destination URL while keeping existing query parameters and fragments intact.
Build a UTM LinkPaste an original and changed version to see added, removed, and modified lines side by side or in a unified report, all in your browser.
Compare Your TextCreate one string or a full batch using lowercase letters, uppercase letters, numbers, symbols, and optional custom characters.
Generate StringsPaste parts lists, shopping lists, asset notes, or plain number lists, then get an instant total. Currency-marked lists ignore dates, model names, week numbers, and other stray digits.
Total Your ListPaste a title, heading, product name, or phrase, then turn it into a lowercase URL slug. Choose dash or underscore separators and optionally remove stop words or numbers.
Generate Your SlugEnter a URL to inspect title, description, preview image, Open Graph tags, Twitter card tags, missing metadata, and suggested social preview code.
Check Your PreviewDrop in a favicon.ico file to preview it on dark or light checkerboard backgrounds, zoom in closely, and see which icon sizes are bundled inside.
