What Are Online Text Tools?
Online text tools are browser-based utilities that help you manipulate, format, analyze, and transform text without installing software. Writers use them to count characters for social media posts, developers use them to test regex patterns and format code, designers use them for placeholder text, and editors use them to compare document versions and spot differences.
How to Use These Tools
Each tool works directly in your browser — no sign-up, no install. Paste your text, make selections, and results appear instantly. The Character Counter shows real-time counts for Twitter, LinkedIn, and SMS. The Case Converter transforms text to UPPERCASE, lowercase, Title Case, or sentence case. The Prefix/Suffix Adder bulk-adds text to every line in seconds.

Frequently Asked Questions
What is the character limit for Twitter/X posts?
Twitter/X allows 280 characters for standard accounts (URLs count as 23 characters regardless of length). Premium subscribers can post up to 25,000 characters. Our Character Counter shows a real-time Twitter count with color-coded warnings.
What is a regex and how do I test one?
A regular expression (regex) is a pattern for matching text: \d+ matches digits, [a-z]+ matches lowercase letters, ^Hello matches lines starting with "Hello". Our Regex Tester highlights all matches live with support for global, case-insensitive, and multiline flags.
How do I add a prefix to multiple lines at once?
Use the Prefix/Suffix Adder. Paste your text, enter a prefix (e.g., "- " to make bullet points) and/or suffix, and every line is updated instantly. Options to skip empty lines prevent adding prefixes to blank rows.
What is lorem ipsum text used for?
Lorem ipsum is standard placeholder text used in design and development to fill space before real content is ready. Our Lorem Ipsum Generator creates any number of words, sentences, or paragraphs on demand.
How do I compare two versions of text?
Use the Text Diff tool. Paste original text on the left, modified text on the right — additions highlight in green, deletions in red, line by line. Ideal for comparing document versions or reviewing edits.
