Property and estate agent websites carry a heavy image burden — large gallery photos, agent headshots, area maps, and blog imagery. Poorly optimised images are the primary cause of slow property websites, which directly drives away potential buyers and sellers. At imgresizr.com, you can optimise all images for a property website, for free.

How to Optimise Property Website Images at imgresizr.com
Upload each image type to imgresizr.com. For listing thumbnails (the small images shown in property search results), resize to 400×267px — this is the size they actually display, so serving larger images wastes bandwidth. Convert all images to WebP using the Convert tool for 25–35% file size reduction. Use the Compress tool to target: hero images under 300KB, thumbnails under 50KB, gallery images under 300KB, agent headshots under 100KB. Use the Enhance tool to ensure all property photos are consistently bright and appealing. Use the Resize tool to batch-process images to consistent dimensions for each category. Check your website's Google PageSpeed Insights score after each optimisation batch.
Property Website Image Tips
- Implement lazy loading — only load listing images when they scroll into view
- Use a CDN — property websites often have high image loads; CDN delivery is essential for UK and global performance
- Consistent image dimensions in search result listings create a professional, polished grid layout
- Alt text every image — search engines use alt text for image indexing and it is legally required for accessibility
