Switch text between capitals and small letters in one click. Paste your text and choose lowercase or UPPERCASE — accents, numbers and line breaks are kept.

Convert uppercase to lowercase

Text typed with Caps Lock on, copied from a PDF or pasted from a spreadsheet often arrives in capitals. Paste it above with lowercase selected to turn every letter small. Then, if needed, apply sentence case to restore capitals at the start of sentences.

In German, “ß” has no traditional capital form, so uppercase writes it as “SS” (straße → STRASSE), following standard Unicode rules.

Changing case in Word, Google Docs and Excel

If you're already working in an office app, these built-in options are handy:

  • Microsoft Word: select the text and press Shift + F3 to cycle through lowercase, UPPERCASE and Capitalize Each Word.
  • Google Docs: Format → Text → Capitalization.
  • Excel and Google Sheets: use the formulas =LOWER(A1), =UPPER(A1) or =PROPER(A1).

For sentence case, title case or anything outside those apps, the converter on this page is faster.

Frequently asked questions

How do I change uppercase to lowercase without retyping?

Paste the text above, select lowercase and press Copy result. It takes a few seconds and works on any device.

Does converting to lowercase remove accents?

No. Accented letters stay accented: “ÉTÉ” becomes “été” and “AÇÃO” becomes “ação”.

Is there a keyboard shortcut to change case?

In Microsoft Word, Shift + F3 cycles through cases. Most other apps don't have one, which is why an online converter is useful.
