Page Size Checker — online
Check the size of any webpage.
Server-Side Tool
Page Size Checker requires making HTTP requests to external servers, which is blocked by browser security policies (CORS). This feature requires a server-side implementation.
Coming Soon
We are building a backend API to support this tool. Check back soon!
In the meantime, try these alternatives:
- Use browser developer tools (F12 → Network tab)
- Check online services like MXToolbox, Cloudflare Radar
- Use curl or wget from your terminal
How to use Page Size Checker
Enter the webpage URL
Click the input field labeled 'Enter URL' at the top of the tool. Type or paste the complete webpage address (e.g., https://www.example.com) into the text box. Ensure the URL includes 'https://' or 'http://' at the beginning for accurate results.
Click the 'Check Size' button
Press the blue 'Check Size' button located directly below the URL input field. The tool will begin analyzing the webpage and downloading all associated resources including HTML, CSS, JavaScript, images, and fonts.
Review the size breakdown results
View the results panel showing total page size in KB/MB, individual resource sizes (HTML, CSS, JS, images, fonts, media), load time estimates, and resource count. Use the detailed table to identify which elements consume the most bandwidth.
Export or compare results
Click the 'Download Report' button to save results as a PDF, or use the 'Compare' feature to analyze multiple URLs side-by-side and identify size optimization opportunities across similar pages.
