The Problem with Scaling in HTML

A common mistake developers make is uploading a 4000x3000 pixel image and using CSS to display it at 400x300. While it looks fine, the user's browser still has to download the massive original file, ruining performance.

Server-Side Resizing

The correct approach is to physically resize the image file before uploading it to your site. By doing this, you reduce both the dimensions and the file size.

Tools You Can Use

You don't need expensive desktop software like Photoshop. You can use our free, browser-based Image Resizer. Simply upload your photo, type in your desired width and height, and download the perfectly sized image instantly.
