Convert Text to Lowercase
Turn any text into lowercase in one click — including a paragraph typed with Caps Lock on. Sentence case, Title Case and the developer formats are here too.
Converting text to lowercase makes every letter small. It is a one-way transformation: capitals carry information about names and sentence starts, and that information cannot be recovered once removed.
How it works
- 1Paste your text. Any length — a word, a paragraph, a whole document.
- 2Click lowercase. It is the first button and applies instantly.
- 3Or pick another case. Sentence case, Title Case, camelCase and the rest are alongside it.
- 4Copy the result. One button copies the converted text.
When you actually want lowercase
More often than you would think. Email addresses are conventionally lowercase and many systems compare them that way. URL slugs are lowercase by convention and case-sensitively different on Linux servers, so a stray capital genuinely breaks links. Hashtags and usernames are usually lowercased for consistency. CSS class names, database column names, and most configuration keys are lowercase. And sometimes it is purely stylistic — a brand voice that writes everything in lower case, or a designer who wants the CSS to control capitalisation rather than the content.
Fixing a paragraph typed with Caps Lock on
The classic use case, and the one worth understanding properly. Converting ALL CAPS to lowercase gives you every letter small — including the ones that should have stayed capital. “I MET JOHN IN MARCH” becomes “i met john in march”. For that reason, Sentence case is usually the better button: it lowercases everything and then restores the capital at the start of each sentence, which gets you most of the way there in one step. You will still need to fix names, places, months, and brands by hand.
Why capitalisation cannot be restored automatically
This is worth being clear about because people expect more than is possible. Uppercasing destroys information. In “BROWN”, nothing distinguishes the surname Brown from the colour brown — the distinction lived in the capitalisation you removed. No tool can recover it from the text alone, because the information is genuinely gone rather than hidden. A tool that guessed would be wrong often enough to be worse than useless. Expect to restore proper nouns yourself after any conversion out of ALL CAPS.
Lowercase in CSS versus lowercase in content
If you are building a web page and want text displayed in lowercase, `text-transform: lowercase` in CSS is usually the better answer than converting the content. It keeps the real capitalisation in your HTML — which matters for screen readers, for search engines, and for the day you change the design — while displaying it however you like. Convert the actual content only when the lowercase form is the true value, as with an email address or a URL slug.
What this does not change
Case conversion is a character transformation. It does not alter your words, your sentence structure, or how the writing reads, and it cannot make a machine-written draft read human — that comes from rhythm and word choice rather than capitalisation. If that is what you are here for, the free AI detector will tell you where the text stands and the humanizer rewrites what it flags.

Frequently asked questions
How do I convert text to lowercase?
Paste your text above and click “lowercase” — it is the first button and applies instantly. Then use Copy to take the result. There is no limit and no account needed.
How do I fix a paragraph I typed in ALL CAPS?
Use Sentence case rather than lowercase: it makes everything small and then restores the capital at the start of each sentence. You will still need to re-capitalise names, places and months by hand.
Can it restore capital letters on names automatically?
No, and no tool can. Uppercasing removes the information that distinguishes “Brown” the name from “brown” the colour, so it cannot be recovered from the text alone.
Is there a shortcut in Word or Google Docs?
Word cycles through cases with Shift+F3, and Google Docs has Format → Text → Capitalisation. This page is faster when you are moving text between apps anyway and does not touch document formatting.
Should I lowercase text in HTML or with CSS?
Use CSS `text-transform: lowercase` for display, which keeps the real capitalisation in your markup for screen readers and search engines. Convert the content itself only when lowercase is the true value, like an email address.
Is my text private?
Yes — the conversion runs entirely in your browser. Nothing is uploaded or stored.
Do I need an account?
No. There’s no sign-up and no install — open the page and start typing.
Does it work on mobile?
Yes — it works in any modern browser on phone, tablet, or desktop.
