How to Resize Images with PHP Before and During Upload

Images often need to be resized for various reasons such as web performance optimization, fitting into design layouts, or complying with application limits. PHP, being a versatile and widely-used scripting language, provides a straightforward approach to handle image resizing. Let's explore how you can resize images on upload and before upload in PHP, while maintaining the aspect ratio.

Why Resize Images?

Resizing images helps to control the file size, which is crucial for reducing load times and saving bandwidth. It also ensures that images fit properly on your web page or application, enhancing the overall user experience.

Resizing Images on Upload

Resizing images directly during the upload process is often the most efficient strategy. This technique eliminates the need for storing large files and reduces the server's work. Here's a basic PHP script to resize images as they are uploaded:

Resizing Images Before Upload

Sometimes, it may be more practical to resize images before they are uploaded, especially if you want to reduce the workload on the server. This can be done using JavaScript to resize the image client-side before sending it to the server. While this post focuses on PHP, you can combine client-side resizing with server-side validations to create an efficient workflow.

Maintaining Aspect Ratio

When resizing images, it's crucial to maintain the aspect ratio to prevent distortion. As demonstrated in the example script above, the aspect ratio can be maintained by calculating proportions based on the original dimensions.
