A standalone infinity sign is quick to insert in Word. When infinity appears inside a formula from a screenshot, PDF, or note, Miss Formula can turn the image into an editable Word equation.
Quick answer: For a Word equation, press Alt+=, type \infty, then press Enter. For a standalone infinity symbol in Word for Windows, type 221E and press Alt+X to insert ∞.
Use Word's equation box when you need an infinity sign inside a short mathematical expression.
Use the Unicode shortcut when you only need the infinity symbol in text, a label, or a table cell.
Use Miss Formula when an integral, limit, series, or interval with infinity is locked in an image.
After recognition, export recognized formulas to one Word file with one click for notes, assignments, or drafts.
Miss Formula runs in your browser, so you can move from formula images to Word-ready equations without a download.
Retain LaTeX alongside Word output when the same formula belongs in papers, technical notes, or online work.
Take a screenshot of an expression with infinity from a PDF, slide, scanned note, webpage, or textbook page.
Drop the formula image into Miss Formula or paste it from your clipboard in the online workspace.
Copy the recognized Word-ready equation into your document instead of rebuilding its structure by hand.
Recognized formulas can be exported to one Word file with one click when you need a ready-to-edit document.
For a simple infinity sign, use Word's built-in tools: in an equation box, press Alt+=, enter \infty, and press Enter; for a standalone symbol in Word for Windows, enter 221E and press Alt+X. The result is the infinity symbol, ∞.
Typing one symbol is fast. Recreating an entire expression becomes slower when infinity appears as the bound of an integral, inside a limit, in an infinite series, or with fractions, exponents, Greek letters, and nested notation. In those cases, most of the work is restoring the formula structure around the symbol.
Miss Formula provides a smoother Word-focused workflow: screenshot or upload the formula, receive Word-ready output, and paste it into Word as an editable equation. You can also retain LaTeX when your work spans other technical writing formats.
Microsoft's official Math AutoCorrect guide identifies the infinity equation command and Unicode value, while Microsoft also documents Unicode character entry in Word. This guide uses Enter for equation conversion based on tested Word behavior.
You can start with initial free credits to try formula screenshots that include infinity symbols, limits, or series. For ongoing work, visit the Miss Formula pricing page to compare available plans.
Should an infinity sign be plain text or an equation?
Use plain text when it is simply a symbol in a sentence or label. Use an editable equation when it belongs to mathematical notation such as a limit, integral, series, or interval.
Can Miss Formula convert a formula with infinity from a screenshot?
Yes. Paste or upload the image, then copy the recognized expression into Word as an editable equation.
Can I keep LaTeX output too?
Yes. Miss Formula provides LaTeX as well as Word-friendly output for the recognized formula.
For expressions that include more than a standalone infinity sign, use Miss Formula to turn a screenshot into an editable Word equation online.
