      <h2 id="general">1. General Questions</h2>
      <div class="faq-group">
        <details class="faq-item">
          <summary>How do I download Facebook videos and Reels?</summary>
          <p>Copy the URL of any public Facebook video or Reel. Paste it into the input box on our homepage, select your preferred video resolution (4K, 1080p, 720p, or MP3 audio), and the download starts instantly.</p>
        </details>

        <details class="faq-item">
          <summary>Is FB4KDownloader completely free?</summary>
          <p>Yes, our tool is 100% free with unlimited downloads. You do not need to register an account, download third-party software, or provide payment details.</p>
        </details>

        <details class="faq-item">
          <summary>Can I download private Facebook videos?</summary>
          <p>No. FB4KDownloader strictly processes public videos and reels. We respect privacy settings, closed groups, and personal friend-only posts.</p>
        </details>
      </div>

      <h2 id="resolutions-4k">2. Video Quality &amp; 4K Upscaling</h2>
      <div class="faq-group">
        <details class="faq-item">
          <summary>How does the 4K Ultra HD resolution option work?</summary>
          <p>Facebook streams content natively at a maximum resolution of 1080p or 720p. Our 4K option fetches the highest native quality master stream and applies high-bitrate spatial scaling (2160x3840 for 9:16 vertical reels, 3840x2160 for 16:9 landscape videos). It is clearly labeled as upscaled so you have full transparency.</p>
        </details>

        <details class="faq-item">
          <summary>What video formats are supported?</summary>
          <p>Videos are delivered in standard MP4 format (H.264/AAC), which is natively compatible with all modern smartphones, tablets, video editors (Premiere, CapCut, DaVinci), and media players (VLC, QuickTime, Windows Media Player).</p>
        </details>
      </div>

      <h2 id="audio-mp3">3. Audio (MP3) Extraction</h2>
      <div class="faq-group">
        <details class="faq-item">
          <summary>How do I convert a Facebook video to MP3?</summary>
          <p>When you paste the video URL, select the <strong>Audio (MP3)</strong> format card. Our server will extract the original audio stream and package it as a clean MP3 file (128kbps to 320kbps) without video track overhead.</p>
        </details>
      </div>

      <h2 id="privacy-apps">4. Privacy, Extensions &amp; Mobile Apps</h2>
      <div class="faq-group">
        <details class="faq-item">
          <summary>Do you keep copies of downloaded videos?</summary>
          <p>No. Videos are streamed directly through RAM memory buffers to your browser. We never store copies on our hard drives, maintaining zero persistent archives.</p>
        </details>

        <details class="faq-item">
          <summary>How does the official Chrome Extension work?</summary>
          <p>Our official Chrome Web Store extension adds a direct 1-click download button beneath videos and Reels as you browse Facebook. You can install it for free from the <a href="https://chromewebstore.google.com/detail/fb4kdownloader-%E2%80%94-4k-faceb/ppaccglfffbbilgiogijkggcldkmfbkh" target="_blank" rel="noopener">Chrome Web Store</a>.</p>
        </details>

        <details class="faq-item">
          <summary>Is there an Android App?</summary>
          <p>Yes! An official FB4KDownloader Android application is currently in beta testing and will be launching soon on the Google Play Store. In the meantime, our responsive website works smoothly on all mobile web browsers.</p>
