Usage Guide
YouTube Thumbnail Downloader is a visual tool for designers and creators. Adjust the controls and sliders to customize your output — pick colors from a wheel, upload images, or choose from presets. The preview updates in real time so you see exactly what you are creating. When satisfied, copy the CSS code or export your design as an image file.

- Start with a color scheme or image that reflects your brand identity
- Use the accessibility checker to ensure your designs meet WCAG contrast standards
- Export multiple variations to test different design directions
- Lock elements you like before making further adjustments
- Save your export settings for consistent output across projects

Does it work offline?
Most tools run entirely in your browser using client-side JavaScript. Once the page is fully loaded, many features work without an active internet connection. However, the initial page load requires internet access.

Your data never leaves your browser. All processing happens client-side — nothing is uploaded to any server. You can verify this by checking the browser Developer Tools network tab while using the tool.
