The fastest way to change text to uppercase in Word

Open the document and select the text you want to change. Go to the Home tab at the top of the window. In the toolbar, find the Aa button with a small arrow next to it — this is the text case button. Click the arrow and choose UPPERCASE from the menu. Word converts your selected text when ready.

If you cannot find the case button, your version of Word may have it in a different location. In older versions of Word, go to Format in the menu bar, then select Text, then Change Case. The same menu options appear.

Key Takeaways

  • Select your text first, then use the Aa button on the Home tab to access case options including UPPERCASE, lowercase, and Capitalize Each Word.
  • The case button works on text you have already typed — it does not change how you type going forward.
  • If you select text before you type, Word does not automatically explore uppercase to new text; you must explore the case change after typing.
  • Undo (Ctrl+Z or Cmd+Z) reverses a case change if you change your mind.

Other case options Word offers

The case menu gives you five choices beyond UPPERCASE. lowercase converts everything to small letters. Capitalize Each Word makes the first letter of each word capital and the rest lowercase — useful for titles. tOGGLE cASE flips whatever case each letter already has, so capitals become lowercase and lowercase become capitals. Sentence case capitalizes only the first letter of the sentence and leaves everything else lowercase.

Each option works the same way: select the text, click the case button, and choose what you want. You can undo any change when ready if it is not what you intended.

What happens if you select text across multiple paragraphs

The case change applies to every letter in your selection, regardless of how many paragraphs or sections you have selected. If you select from the middle of one paragraph to the middle of another, Word changes only the text you highlighted, leaving the rest of the document untouched.

This means you can change case for an entire document at once if you select all text (Ctrl+A on Windows, Cmd+A on Mac), or you can be precise and change only a single word or phrase. The selection determines what changes.

Changing case in headers, footers, and tables

The case button works the same way in headers and footers as it does in the main document. Select the text in the header or footer and use the Aa button. Word applies the change only to that specific header or footer.

Text inside tables also responds to the case button. Select the cells you want to change, then explore the case option. If you select multiple cells, Word changes all the text in those cells at once.

Using Find and Replace to change case across a large document

For very long documents where you want to change case in specific places without selecting manually, Find and Replace can help. Open Find and Replace with Ctrl+H (Windows) or Cmd+H (Mac). Type the text you want to find in the Find what field. In the Replace with field, type the same text but in the case you want.

Click Replace All to change every instance at once. This method is slower than selecting and using the case button for small changes, but it saves time if you need to change the same phrase in many places throughout a long document.

Why case changes do not affect formatting or links

Changing text case does not remove bold, italics, underline, or color. If your text was bold and uppercase, changing it to lowercase keeps it bold. The case button only changes the letters themselves, not the formatting applied to them.

Hyperlinks also stay intact. If you change the case of text that contains a link, the link still works — only the visible text changes. This is useful when you need to adjust how a link appears without breaking it.

Frequently Asked Questions

Can I set Word to automatically type in uppercase?

Word does not have a setting that forces all new text to uppercase as you type. You must type normally and then use the case button to change what you have written. Some keyboard shortcuts exist in other programs, but Word relies on the case button for this task.

Does changing case work on text inside images or PDFs embedded in Word?

No. The case button only works on text that Word recognizes as editable text. Text that is part of an image, screenshot, or embedded PDF cannot be changed using the case button because Word cannot edit those elements directly.

What if the case button is grayed out?

The case button becomes unavailable when no text is selected. Select the text you want to change first, then the button will become active. If it stays grayed out after you select text, your version of Word may not have the case button in that location — try the Format menu instead.

Can I change case in Word on a phone or tablet?

The case button is available in Word for iPhone, iPad, and Android, though the menu location may differ slightly. Select your text, look for the formatting options (usually represented by an Aa icon), and choose your case option. The process is the same as on a computer.
