How to Compress Images for Your Website
Quick Answer
Large image files are one of the most common reasons websites load slowly. Compressing them before uploading can cut file sizes by 50–80% with no visible quality loss — and it directly improves your Google page speed score.
1.Go to Squoosh
Visit squoosh.app — it's free, runs in your browser, and requires no account.
2.Upload your image
Drag and drop your photo onto the page.
3.Select WebP as the output format
On the right side, change the format dropdown to WebP. This is the format Google recommends for web images.
4.Adjust the quality slider
Start at 75–80%. You'll see a side-by-side preview. The difference is usually invisible to the eye but the file size drops dramatically.
5.Download and upload to your site
Click Download and use this compressed version when uploading to your website.
Tip: Aim for images under 200KB. A photo straight from your phone can easily be 4–6MB — that's 20–30× larger than it needs to be, and it slows your whole page down.
