text

Decode Base64 to text or encode text to Base64. Paste into the top box, read the result below, and flip the direction with one click. Handles Unicode correctly and reads URL-safe Base64 too.

Remove duplicate lines from a list or text, keeping the first occurrence. Optionally ignore case and whitespace, or drop blank lines too.

Replace text in two modes: plain find and replace all, or regular expressions with flag controls and capture group references like $1.

Generate placeholder text: pick how many words, sentences or paragraphs you need, optionally starting with the classic Lorem ipsum opening, and copy the result.

Sort the lines of a text alphabetically, naturally, by length, by numeric value or shuffled. Reverse the order with a switch, and optionally trim lines, drop blank lines and remove duplicates in the same pass.

Convert text into every case at once: title case in the APA, AP, Chicago, MLA, Bluebook, AMA and NYT styles, sentence case, upper, lower, camelCase, snake_case, kebab-case and more, each with its own copy button.

Count words, characters, sentences, paragraphs, lines and more as you type, with estimated reading and speaking time.
