Summary: Freeze LQIP placeholders on the frontend to see exactly what visitors see before images load. Useful for visual testing and fine-tuning placeholder quality.

Preview Mode freezes LQIP placeholders on the frontend - images never get replaced by the real photo. It the easiest way to check exactly what your visitors see during the loading moment.

## How to Enable

1. Go to **LQIP Settings**
2. Scroll to the **Testing** card at the bottom
3. Enable **LQIP Preview Mode**
4. Save settings
5. Visit your site while logged in as an admin

## What You'll See

- Lazy loading is completely disabled - every image stays as its placeholder permanently
- A small **LQIP Preview** badge appears in the bottom-right corner of the page to remind you it's active
- The active LQIP type determines what each placeholder looks like:
    
    
    - **Thumbnail** - blurred, downscaled version of each image
    - **Palette** - solid dominant color, color columns, or gradient
    - **Pixelart** - mosaic pixel grid
    - **Primitives** - geometric SVG shapes over an average-color background

Preview Mode is only visible to **logged-in administrators**. Regular visitors see the normal site with lazy loading fully active - Preview Mode has no impact on their experience.

Use Preview Mode to fine-tune your LQIP settings visually. Enable it, browse to a page with images, check the placeholder quality, then adjust settings (blur, shape count, palette type) and re-generate.

## Remember to Disable

Turn Preview Mode off when you're done testing. It adds minor overhead for admin users and is only useful during configuration.
