StatusQueen's lowercase to UPPERCASE tool turns any text into UPPERCASE in one click. The action row also offers six other cases — lowercase, Sentence case, Title Case, Capitalized, alternating, and inverse — so this single page covers every common case transformation.
Advanced options that make it different
- Preserve acronyms — runs of 3+ uppercase letters in a row stay uppercase even when other text gets lowercased.
- Keep URLs and emails as-is — anything matching
http://,https://, or an email pattern is left untouched. - Process each line independently — every line is treated as its own piece of text.

When to use this vs Convert Case
- This page — when UPPERCASE is the primary action you want, with optional smart preservation.
- Convert Case — for the same range of cases without the advanced switches.
Frequently Asked Questions
How do I convert lowercase to UPPERCASE?
Paste your text into the box and click UPPERCASE. Every letter becomes uppercase. The other case buttons work the same way.
What does "Preserve acronyms" do here?
It only matters when you click a button that lowercases text — those keep 3+-letter uppercase runs intact instead of lowercasing them.
Is my text uploaded anywhere?
No. The conversion runs entirely in your browser. Your text never leaves your device — nothing is uploaded, logged, or sent to a server.
Does this work for non-English text?
Yes — accented Latin, Greek, Cyrillic, Armenian and other bicameral scripts all work via the browser's Unicode case mapping.
Can I undo a conversion?
Yes — use your browser's standard undo (Ctrl+Z on Windows / Linux, Cmd+Z on Mac) right after clicking a case button.
