                        <strong>Frame dropping</strong> is the most effective way to compress an already optimized GIF.
                        <br><br>
                        A smooth GIF typically runs at <strong>10–15 FPS</strong>. If your file’s FPS (shown on the file card above) is higher, use these recommendations:
                        
                        <ul>
                            <li>
                                <strong>Above 20 FPS:</strong> Drop every 2nd frame.
                            </li>
                            <li>
                                <strong>15–20 FPS:</strong> Drop every 3rd frame.
                            </li>
                        </ul>

                        <small><em>Note: Dropping frames reduces file size by removing animation detail. Lower the number, the more frames you drop.</em></small>
