Case Converter
Caps lock was on, or the text came out of a PDF with a break at the end of every line. Paste it in, press the case you want, and copy it back out - extra spaces and line breaks can go in the same pass. Everything runs on your device; nothing you paste is uploaded or stored.

Your text is converted on your own device. Nothing you paste here is sent anywhere, saved or stored.
How to convert uppercase to lowercase, or to any other case
- Type or paste your text into the box, or upload a .txt file.
- Press the case you want. The text changes in front of you - there is nothing to submit and nothing to wait for.
- Press Copy, or download it as a text file.
Press the same case again to turn it off and get your original text back. Nothing you paste is uploaded, logged or kept after you close the tab - the conversion happens on your own device, so you can safely run text through it that you would not want to send to a stranger's server.
Which case do you need?
lowercase
CAPS LOCK WAS ONcaps lock was on
Turns capital letters into small letters, so uppercase becomes lowercase without retyping a word. Reach for it when caps lock was on, or when an email address or a tag has to match exactly.
UPPER CASE
notice meNOTICE ME
Puts everything in capitals, for a heading or a label you want people to notice.
Sentence case
the NASA report. it worked.The NASA report. It worked.
Capitalises the first letter of each sentence and leaves the rest alone, so a block of shouting reads like normal prose again. Acronyms such as NASA or PDF keep their capitals.
If the whole text is in capitals, everything comes down - there is no way to tell an acronym from the rest - so put those back by hand.
Title Case
the cat is on the matThe Cat Is on the Mat
Capitalises the words that carry the meaning, verbs and pronouns included, and leaves short words like "a", "of" and "the" in lower case. This is how most headlines and article titles are set.
Capitalise Each Word
the cat is on the matThe Cat Is On The Mat
Capitalises every word without exception, short ones included. Use it where every word should stand out: names, places and column headings.
aLtErNaTiNg
alternating caseaLtErNaTiNg cAsE
Flips between small and capital letters as it goes.
iNVERSE
Hello WorldhELLO wORLD
Swaps whatever you already have, so capitals become small letters and small letters become capitals.
Remove line breaks, extra spaces and tabs
Text copied out of a PDF, an email or a web page usually arrives with spacing you did not ask for. Pick what you want gone from the Remove list and say what should take its place - the box works as a whitespace remover and a line-break remover as well as a case converter.
What each option clears
- Extra spaces - collapses runs of spaces and tabs down to one, and leaves your paragraphs where they are.
- All spaces and breaks - strips every space, tab and line break, leaving one unbroken run of characters.
- Line breaks - joins every line into one, which is what you want for text that was wrapped to a fixed width. Set Replace it with to A space, or the last word of each line will run into the first word of the next. Paragraphs are joined too.
- Blank lines between paragraphs - closes the gaps between paragraphs while keeping the lines themselves separate.
- Tabs - swaps tabs for ordinary spaces.
- Text I type - removes or swaps any word or character you name. It ignores capitalisation, so typing "cat" finds "Cat" too, and it looks for exactly what you typed, punctuation and all.
Whatever you remove, the Replace it with list decides what fills the gap: nothing at all, a space, a line break, or text of your own. Case conversion and tidying run together, so you can lowercase a block of text and close up its spacing in one go.
Changing case in Word and Google Docs
Microsoft Word. Select the text and press Shift + F3 (fn + Shift + F3 on a Mac). Each press moves to the next of lowercase, UPPERCASE and Capitalize Each Word. Sentence case is under Home → Change Case, the "Aa" button. Word for the web has no case change, so paste the text here instead.
Google Docs. Select the text, then Format → Text → Capitalization, and pick lowercase, UPPERCASE or Title Case. Docs has no Sentence case option, which is the usual reason to bring text here and paste it back.
