Project Gallery

A showcase of our work. This page is intentionally loaded with large, unoptimized images to demonstrate mod_pagespeed's image optimization.

About This Page

This gallery contains 8 large images totaling approximately 20 MB of unoptimized image data. With mod_pagespeed enabled, the module automatically:

  • Compresses JPEG images to reduce file size by 40-70%
  • Converts images to WebP format for supporting browsers
  • Resizes images to match their rendered dimensions on screen
  • Adds lazy loading so below-the-fold images load on demand
  • Inlines low-quality preview placeholders for instant visual feedback
  • Converts large PNG images to JPEG when they have no transparency

With mod_pagespeed's AVIF filters enabled, these photographs are also served as AVIF whenever that format comes out smaller than the optimized WebP or JPEG. The format is negotiated per browser through the Accept request header, so each visitor gets the best encoding their browser supports. Add ?ModPagespeed=off to the page URL to compare against the raw originals.

Toggle PageSpeed off using the banner above to compare the raw vs. optimized experience.

Panoramic landscape view

Panoramic Landscape

2400 x 1600 JPEG at quality 98. Original size: ~4.1 MB. mod_pagespeed will compress this significantly and serve WebP to supporting browsers.

Modern office space

Office Interior

1800 x 1200 JPEG at quality 98. Original size: ~2.2 MB. Note how mod_pagespeed also rewrites the image URL to include a content hash for cache-busting.

Team collaboration session

Team Meeting

2000 x 1400 JPEG at quality 98. Original size: ~2.8 MB. With resize_rendered_images enabled, this will be scaled down to match its CSS-constrained width.

Product analytics dashboard

Product Dashboard

1600 x 1200 JPEG at quality 98. Original size: ~2.0 MB. The combination of compression and WebP conversion typically achieves 60-80% size reduction.

Developer workspace

Developer Workspace

1400 x 1000 JPEG at quality 98. Original size: ~1.4 MB. mod_pagespeed's progressive JPEG conversion makes images render progressively during download.

Analytics on screen

Analytics Screen

1200 x 800 JPEG at quality 98. Original size: ~970 KB. Even smaller images benefit from optimization — every kilobyte matters on mobile networks.

Product icon variant 1

PNG Image (No Transparency)

800 x 800 PNG, 16-bit depth. Original size: ~3.0 MB. Since this PNG has no transparency, mod_pagespeed can convert it to JPEG for massive size reduction.

Product icon variant 2

Another Large PNG

800 x 800 PNG, 16-bit depth. Original size: ~2.9 MB. The PNG-to-WebP conversion alone can reduce this image to under 100 KB without visible quality loss.
