Fix caps lock text — accidentally typed in caps
Did you type a paragraph with caps lock on by mistake? Paste it here and convert to lowercase or sentence case in one tap. Built specifically for the "oh no I just typed a long message in all caps" moment — recover the text without retyping. "Fix caps lock text" / "all caps to normal text" / "accidentally typed in caps" all land here. You've just typed a 200-word email reply with caps lock on. Instead of holding shift to retype the whole thing, paste the all-caps text into the input, click Sentence Case, copy the output back into the email. Total elapsed time: under fifteen seconds. The recipient gets a normally-cased reply that doesn't look like you were shouting at them. Conversion runs entirely in your browser — pasted text is never sent to a server, never logged. That matters when the text you're cleaning is private (a draft email, a forwarded message, an internal memo). For a related but distinct intent — converting a deliberately-titled string between casing modes for blog posts or headlines — use the title-case page instead.
Frequently asked questions
Should I use lowercase or sentence case for fixing caps-lock text?
Sentence case for prose text — paragraphs, emails, messages where capitalization at sentence starts should be preserved. Lowercase for headers or short phrases that should be all lowercase. "HELLO. HOW ARE YOU?" becomes "Hello. How are you?" with sentence case, or "hello. how are you?" with lowercase. Sentence case is the more common fix.
Will it preserve the original line breaks and paragraph structure?
Yes. Casing changes per character; line breaks, paragraph spacing, and any other whitespace pass through unchanged. Paste a multi-paragraph email and the output keeps the same structure with only letter casing affected. The recipient gets the same visual layout as your original draft, minus the caps-lock damage.
Is anything I paste sent to a server or logged?
No. Conversion runs entirely in your browser — pasted text never leaves your device, never hits a server, never gets logged. Safe to paste forwarded private emails, draft messages, internal memos, or any text you'd rather not have indexed. There is no analytics on the input field, no third-party tracker, no server-side endpoint that touches what you typed.
What if my text mixes proper nouns I want to keep capitalized?
Sentence case will lowercase proper nouns (names, places, brands) along with everything else, then capitalize only the first letter of each sentence. After conversion, manually re-capitalize the proper nouns. For text with many proper nouns, the manual cleanup may be faster than retyping; for short prose with few names, conversion plus quick manual fixes is usually the win.
