Page Size Checker — See What's Making Your Page Heavy
Enter a URL to see the total page weight — including HTML, CSS, JavaScript, images, and fonts — broken down by resource type, so you can pinpoint exactly what's slowing the page down.
Why page weight matters
A heavier page takes longer to download, especially on mobile connections or slower networks, which directly affects how quickly visitors see content and can interact with the page. Since page speed is a ranking factor and a major driver of whether visitors stay or bounce, trimming unnecessary weight is one of the more direct ways to improve both.
What it breaks down
- Total page size — the combined weight of everything the browser has to download to render the page
- By resource type — images, scripts, stylesheets, and fonts shown separately, so you can see which category is contributing the most
- Largest individual files — flagging the specific images or scripts most worth optimizing first
Common culprits behind a bloated page
- Unoptimized images — a photo straight from a camera or phone, uploaded without compression, is often 5-10x larger than it needs to be for web display
- Unused CSS or JavaScript — leftover code from a theme or plugin that loads on every page even when that page doesn't use it
- Too many third-party scripts — analytics, ad networks, and chat widgets each add their own weight and often load render-blocking resources
How it works
- Enter the URL you want to check
- Review the total weight and the resource breakdown
- For a full picture of how that weight translates into actual load time, pair this with our Page Speed Checker, which also factors in server response time and rendering, not just total file size
Who this is for
- Developers auditing a page before launch
- Site owners troubleshooting a slow-loading page
- Anyone optimizing images and assets to improve Core Web Vitals scores
