How to create a bulk image resize tool website

by

To create a bulk image resize tool directly in WordPress without creating a plugin, you can create a custom WordPress page template that allows users to upload images and resize them. Here’s a simple way to approach it using PHP and HTML, leveraging WordPress functionalities:

Steps:

  1. Create a Custom Page Template
  2. Add Image Upload and Resize Functionality
  3. Display Results

Step 1: Create a Custom Page Template

  1. Go to your WordPress theme folder (usually wp-content/themes/your-theme/).
  2. Create a new file, e.g., page-bulk-resize.php.
  3. Add the following code:

Step 2: Add Page in WordPress Admin

  1. In your WordPress admin dashboard, go to Pages → Add New.
  2. Title your page and in the right sidebar under Template, select “Bulk Image Resize”.
  3. Publish the page.

Step 3: Test the Tool

  1. Go to the new page you’ve created.
  2. Upload multiple images, input desired width and height, and resize the images.
  3. The resized images will be saved in the uploads folder of your WordPress installation.

Notes:

  • This solution uses PHP’s imagescale() to resize images.
  • Ensure the image types are supported (JPEG and PNG in this case).
  • You might want to extend it to handle other formats, like GIF or WebP.
  • Make sure that your PHP environment has the GD library enabled to support image manipulation.

This approach avoids creating a plugin, while giving you a functional page for bulk image resizing. Let me know if you need further enhancements!
