About
About Convert Case Online
A free utility built for anyone who needs to change text capitalisation without retyping.
What we do
Convert Case Online is a free, browser-based text case converter. Paste your text, click a button, done. No software to install, no account to create.
Why we built it
It started with accidentally writing a whole paragraph in caps lock and having no quick way to fix it. Retyping felt absurd. We built this so nobody ever has to retype text just to change its capitalisation.
Our principles
- Free, always. No premium tier, no paywalled features.
- Private by design. Every conversion happens in your browser. Your text never leaves your device.
- No friction. No sign-up, no download. Open the page, use the tool.
- Fast. Conversions are instant even on large documents.
Who uses it
- Writers and editors fixing formatting after pasting from various sources.
- Developers converting strings between formats.
- Students formatting essays and citations correctly.
- Marketers formatting ad copy and captions.
- Anyone who left caps lock on.
