Text abbreviation translator

Abbreviation dictionary

Text abbreviation translator

Paste a message full of internet and SMS shorthand and this tool expands every abbreviation it recognizes to its full meaning — "brb" becomes "be right back", "tbh" becomes "to be honest", and so on across a built-in dictionary of more than 250 common terms. It's built for anyone who needs to read old-school chat slang in plain English: a parent decoding a teenager's texts, a moderator reviewing forum posts, or a writer double-checking what an acronym in a draft actually stands for.

The Direction option flips the operation: switch to "Shorten to abbreviations" and the tool scans your text for phrases it knows — "for your information", "laughing out loud", "talk to you later" — and swaps them for the matching abbreviation instead, which is handy for drafting texts or captions that need to fit a tight character limit. Turn on "List found abbreviations with meanings" to get a plain-language glossary appended under the result, listing every term the tool matched and what it means, useful when you want the expansion and a quick-reference key at once.

Matching is whole-word only, so "lolcat" is left alone even though it contains "lol", and every match keeps the surrounding punctuation and capitalization: "LOL" expands to "LAUGHING OUT LOUD", "Btw" becomes "By the way", and a comma or exclamation mark right after an abbreviation stays exactly where it was. Anything the dictionary doesn't recognize — regular words, names, emoji, text in other languages — passes through completely unchanged. The full dictionary is also printed as a reference table below the tool, so you can look up a term without running a conversion at all.

Everything runs locally in your browser; no text is ever uploaded. When you're happy with the result, copy it, download it as a .txt file, or send it straight into another tool's input to keep working on it.
