Case Changer

Convert text to UPPERCASE, lowercase, Title Case or Sentence Case instantly. Grabs your page selection. Works offline.

Case Changer is the fastest way to fix text case in Chrome. Highlight text on any web page, or paste it into the popup, and convert it to UPPERCASE, lowercase, Title Case or Sentence Case in a single click. No sign-up, no account, no waiting for a server — every conversion happens instantly inside your own browser. WHAT IT DOES • UPPERCASE — shout it, or fix a heading that was typed in lower case • lowercase — strip out accidental caps lock in one click • Title Case — proper headline style using AP rules, so short words like "the", "of" and "to" stay lowercase where they should • Sentence case — turn a wall of capitals into readable paragraphs • Grab selection — pull whatever you highlighted on the page straight into the popup • Replace on page — write the converted text back into the text box you highlighted • Live counters for characters, words and lines • Undo, so a mis-click never costs you your text • Dark and light themes that follow your system setting FREE FOREVER All four case conversions, the page-selection grabber, the replace-on-page tool, the counters and the undo history are completely free. There is no trial, no watermark and no ad. PREMIUM — £1.99, ONE OFF • One-click Copy to Clipboard — send the converted text straight to your clipboard • Saved snippet history — keep up to 50 reusable snippets, stored locally on your machine and never uploaded One payment. No subscription, no account, no renewals. PRIVACY Your text is processed entirely on your own machine and never leaves it — not the text you convert, not your saved snippets, not the selections you pull off a page. The only network request the extension ever makes is a licence check to extensionpay.com when you open the popup, and that check carries no text of any kind. Payments are handled by Stripe; your card details are never seen or stored by this extension. WHO IT IS FOR Anyone who works with text all day and has ever pasted a headline in ALL CAPS by mistake.
