How to convert text to uppercase

Paste or type your text in the Input box.
Click UPPERCASE (or any other case style) in the Conversion options row.
The result appears in the Output box immediately, click Copy result or download it as a.txt file.

Everything happens locally: your text never leaves your browser, which is why this tool is safe for client copy, internal documents and anything else you'd rather not paste into a server side converter.

What "Title Case" actually does

Title case capitalises the first letter of each significant word but leaves short articles, conjunctions and prepositions lowercase: the, a, an, and, but, or, for, of, to, in, on, at, by, with, from. The first and last words are always capitalised, and so is any word following a colon or dash.

When uppercase hurts readability

Long runs of ALL CAPS slow reading down because every letter occupies a uniform rectangular block, removing the word shape cues readers rely on. Best practice:

Keep uppercase phrases short, a few words at most, or a single headline.
Never set a paragraph in caps. Screen readers may also spell out capitalised words letter by letter in some configurations.
Use it for emphasis sparingly, one or two words, not whole sentences.
Avoid it in URLs and email addresses: domains are case insensitive but people mistype capitals.

Writing to a character limit? Case changing doesn't alter the character count, a 280 character post stays 280. Check your limits with our Twitter character counter or the character counter.

Frequently asked questions

Does converting to uppercase change the character count?

No. Case conversion never adds or removes characters, only the letter case changes.

Can I convert back to lowercase?

Yes, click the lowercase option, or use our dedicated lowercase generator.

Does it handle non English letters?

Yes. Accented characters (é, ö, ñ), Greek and Cyrillic text convert correctly using the browser's built in Unicode case mapping.

Can I download the result?

Yes, click Download.txt to save the converted text as a plain text file.

Is there a length limit?

No practical limit. Text tens of thousands of characters long converts instantly.

Case questions

Two things readers ask most.

Does changing case change my character count?

No. Uppercasing or lowercasing keeps the same number of characters, so a 280 character post stays at 280.

When should I avoid all caps?

Long passages in caps slow readers down. Keep uppercase for short labels and one or two words of emphasis.
