Convert to uppercase
For the times caps lock was off when it should have been on, or on when it very much should not. Paste, copy the row you meant.
Guide
How to use it
- Paste the text, the highlighted UPPERCASE row is ready immediately.
- Copy it, or take the lowercase row if you are undoing accidental caps.
- For caps-lock accidents in prose, sentence case is usually the better rescue, it restores capitals where sentences start.
Examples
Uppercase, used well
Passport and payment forms that demand capitals: paste your address, copy the caps version, keep the form validator happy.
Short labels tolerate caps well, buttons, badges, stencilled crate markings. Whole paragraphs in caps read as shouting and slow readers down measurably.
AN EMAIL DRAFTED WITH CAPS LOCK ON converts down via lowercase, then sentence case restores the capitals that belong. Two rows, one rescue.
Method
How it works
Uppercase conversion maps every letter to its capital form using Unicode rules, so accented characters convert correctly (é becomes É) along with A to Z.
The same input feeds every other case on the page, which matters because the fix for accidental caps is rarely more caps, it is sentence case, one row up.
FAQ
Frequently asked questions
Why do forms insist on capitals?
Legacy systems and matching rules, many government and airline databases store names uppercase. Converting before pasting avoids their sometimes-clumsy auto-conversion.
Does uppercase affect accented letters?
Yes, correctly: café becomes CAFÉ. Locale quirks like the Turkish dotless i follow your browser’s rules.
Is typing in caps really harder to read?
Measurably, for running text: word shapes disappear and reading slows around 10 to 20%. Labels and short headings are fine.
How do I fix text stuck in caps?
Lowercase first, then sentence case to restore sentence capitals, both rows are on this page. Proper nouns need a manual pass.
Does it change numbers or punctuation?
No, only letters have cases. Everything else passes through untouched.
Is my text stored?
No, conversion is local and the page keeps nothing.
