+# Copy Math to Word Without Losing Formatting — The Right Way
+
+Most people's first instinct when they need a formula in a Word document is to take a screenshot. It works — until you need to resize the document, change the font, or edit the formula. Screenshots break. Native equations don't.
+
+Here are three ways to get TexPixel's output into Word, from best to worst.
+
+## Method 1: DOCX Export (Best)
+
+The cleanest option. TexPixel converts your recognized formula into a native Word equation (OMML format) and packages it in a `.docx` file.
+
+**How:**
+1. Upload your formula image to TexPixel.
+2. Click **Export** → select **DOCX**.
+3. Open the downloaded file in Word.
+4. Select the equation, copy, paste into your target document.
+
+**Why it's best:** The formula is fully editable in Word's built-in equation editor. Double-click it to open the editor, change any symbol, resize it — it behaves exactly like an equation you typed yourself. It also scales correctly when you change font sizes.
+
+**Limitation:** Each upload produces one `.docx` file. If you have many formulas to insert, you'll need to repeat the process or batch them (see below).
+
+## Method 2: Paste LaTeX into Word's Equation Editor (Good)
+
+Word 2019+ and Microsoft 365 support pasting LaTeX directly into equations.
+
+**How:**
+1. Get the LaTeX output from TexPixel (e.g., `x = \frac{-b \pm \sqrt{b^2-4ac}}{2a}`).
+2. In Word, insert a new equation: **Insert → Equation** (or press `Alt+=`).
+3. Make sure the equation box is in **LaTeX mode** (click the dropdown on the right side of the equation box → select "LaTeX").
+4. Paste the LaTeX string. Press **Enter** or click outside.
+
+Word converts the LaTeX to a rendered, editable equation.
+
+**Why it's good:** Fast for single formulas. No file download required.
+
+**Limitation:** Word's LaTeX parser doesn't support all LaTeX commands. Obscure or complex expressions may not render correctly. Test before relying on it for important documents.
+
+## Method 3: Image Export (Worst, But Sometimes Necessary)
+
+Export the formula as a PNG and insert it as an image in Word.
+
+**When to use:** Only when you need the formula in a document being shared with someone who doesn't have Word's equation editor (e.g., older Word versions, third-party editors). Or when a complex formula doesn't render correctly via Methods 1 or 2.
+
+**Downsides:** Not editable. Doesn't scale well. Accessibility tools can't read it.
+
+## Handling Multiple Formulas
+
+If you have many formulas to insert into a single document:
+
+1. Upload each formula image and collect the LaTeX strings.
+2. Open a new Word document.
+3. For each formula, use the **Alt+=** method above to insert them in sequence.
+4. Once all formulas are inserted, copy and paste the entire equation block into your target document.
+
+This is faster than one DOCX export per formula.
+
+## Google Docs
+
+Google Docs doesn't natively support LaTeX paste. Options:
+
+- Use the **Auto-LaTeX Equations** Google Docs add-on, which renders LaTeX strings as inline images.
+- Export as DOCX and open in Google Docs (equations import as images, not editable).
+- Use a tool like `mathpix-markdown-it` to convert to Markdown and render in a Markdown-compatible environment.
+
+For serious equation-heavy work, Word or Overleaf remain better choices than Google Docs.
