Hey everyone! I'm working in the Real Estate space and often end up with a ton of high-quality images for listings. I've noticed that having 10-16 photos on a page can really slow things down. I'm looking for some best practices:
A) What's the ideal image size for web?
B) Which compression tools do you recommend to reduce image sizes?
C) Any additional tips to speed up my site?
D) Is Google Lighthouse an accurate tool for checking loading times?

Just a quick note: if you're optimizing images before uploading them, remember that some CMSs will re-compress, which might reduce quality and effectiveness. Instead, focus on how your images are handled after the upload—consider using a CDN between your CMS and the users. Imgix is a great tool I’ve had success with for this setup!
For real estate sites, aim for image sizes between 100KB to 200KB, and larger images should be kept under 1MB. Tools like ImageOptim, TinyPNG, and using the WebP format for compression are my go-to's. Combining this with lazy loading and a CDN will really enhance your site’s speed. Google Lighthouse is solid for load time assessments, but it's always good to check against other tools.
Check out tools like Shortpixel, TinyPNG, or Squoosh for compression. To boost your website's speed, make sure to implement Lazy loading, use a CDN, and optimize caching. Also, pick a reliable hosting provider to avoid performance issues.
For compressing images, Tinyjpg works wonders! You can actually name your file with a '-b' or something and compare the compressed version easily to see how effective it is.
If you're using WordPress, I highly recommend the Converter for Media plugin and TinyPNG for compression. Keep image sizes within the container's dimensions and enable lazy loading for images below the fold. Also, Google Lighthouse is great for assessing load times, as it uses real user data, but don’t forget to cross-check with GTmetrix for real-world performance.
