Why Create Custom Image Converter Tools on Your Website?

For starters, it provides a seamless experience for users who frequently need to convert images—no more searching for third-party sites or software. It keeps visitors on your site longer, potentially reducing bounce rates and improving SEO rankings.

Moreover, offering such a utility positions your website as a resource hub, encouraging repeat visits and increasing the likelihood of conversions. It’s also a fantastic way to learn and demonstrate your coding skills, as you’ll be integrating front-end development with WordPress’s robust CMS capabilities.

Step-by-Step Guide for WEBP to PNG Converter Tool with WordPress:

Step 1: Create a WordPress Page for the Tool.

Navigate to your WordPress dashboard, click on ‘Pages’, then ‘Add New Page’. Here, you’ll set up the foundation for your converter tool.

Step 2: Add a New Plugin - shortcoder

Go to ‘Plugins’, then ‘Add New’, and search for the ‘shortcoder’ plugin. This plugin allows you to add custom HTML, CSS, and JavaScript code to your WordPress site in the form of custom short code without editing theme files

Step 3: Generate the Code Using ChatGPT

At this stage, you’ll use ChatGPT to generate the code for your converter tool. The prompt you’ll use should instruct ChatGPT to create HTML, CSS, and JavaScript code for a WEBP to PNG converter.

Magic Prompt:

As an expert in WordPress development with over 10 years of experience in developing image converter and editor tools, your task is to develop code for a tool called “Image to PNG Converter” that can efficiently convert any image, including WEBP, into PNG format. You’ll need to write HTML, CSS, JavaScript, and other necessary code for this tool, all within the same file. Add proper code comments to increase code readability. Additionally, create a user-friendly UI adhering to the following guidelines:

Title: Display the title in bold and centered.
File Selection Button: Below the title, place a button labeled “CHOOSE FILE” with 50% width of the container, white text, and a background color of “#48C031”. Below this button, vertically, display text indicating the selected file’s name. By default, it should show “No file chosen” and include a progress bar indicating image upload status. Also, make them centered to the container.
Image Previewer Section: Below the file selection area, include a section to preview the selected image. This section should only be visible when a user has selected an image; otherwise, it should remain hidden.
Download Link: Once the image is successfully selected and displayed in the preview section, provide an inline link labeled “Download PNG Image” below. This link should be visible only after the image has been converted to the given format. Set the text color with the code “#48C031” and make it underline.
Color Scheme: Utilize the color “#48C031” as the accent color throughout the design.
Responsiveness: Ensure the design is responsive, functioning seamlessly on both mobile and desktop devices.
Hover Effects: Implement hover effects on all options, including buttons and links.

Step 4: Create a New shortcode

Using the ‘shortcoder’ plugin, click on ‘Create shortcode’. Provide a name for the shortcode. For example, you can set the name to “png_converter”. This is where you’ll paste the code generated by ChatGPT.

Code:

				
					<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
  body {
    font-family: Arial, sans-serif;
    text-align: center;
    margin: 0;
    padding: 20px;
  }
  h1 {
    font-size: 24px;
    font-weight: bold;
    margin-top: 20px;
  }
  #choose-file-btn {
    background-color: #48C031;
    color: #fff;
    padding: 10px 40px; /* Adjusted padding */
    border: none;
    border-radius: 5px;
    cursor: pointer;
    margin-top: 20px;
    font-size: 16px; /* Adjusted text size */
    transition: background-color 0.3s ease; /* Hover effect */
  }
  #choose-file-btn:hover {
    background-color: #3DA024; /* Hover color */
  }
  #image-preview {
    margin: 20px auto; /* Center image */
    max-width: 100%;
    height: auto; /* Auto height */
  }
  #download-png {
    display: none;
    color: #48C031;
    font-weight: bold;
    margin-top: 20px;
    text-decoration: underline; /* Underline text */
    transition: color 0.3s ease; /* Hover effect */
  }
  #download-png:hover {
    color: #3DA024; /* Hover color */
  }
</style>
</head>
<body>
  <input type="file" id="file-input" style="display: none;">
  <button id="choose-file-btn">CHOOSE FILE</button>
  <div id="image-preview"></div>
  <a href="#" id="download-png" download>PNG Download</a>

<script>
  const fileInput = document.getElementById('file-input');
  const chooseFileBtn = document.getElementById('choose-file-btn');
  const imagePreview = document.getElementById('image-preview');
  const downloadLink = document.getElementById('download-png');

  chooseFileBtn.addEventListener('click', function() {
    fileInput.click();
  });

  fileInput.addEventListener('change', function() {
    const file = this.files[0];
    if (file) {
      const reader = new FileReader();
      reader.onload = function(e) {
        const image = new Image();
        image.src = e.target.result;
        image.onload = function() {
          const canvas = document.createElement('canvas');
          canvas.width = image.width;
          canvas.height = image.height;
          const ctx = canvas.getContext('2d');
          ctx.drawImage(image, 0, 0);
          const pngData = canvas.toDataURL('image/png');
          imagePreview.innerHTML = '';
          imagePreview.appendChild(image);
          downloadLink.setAttribute('href', pngData);
          downloadLink.style.display = 'inline-block';
        };
      }
      reader.readAsDataURL(file);
    }
  });
</script>
</body>
</html>

Step 5: Add the shortcode to Your Tool Page:

Back in the WordPress dashboard, navigate to your PNG Converter page and add a ‘shortsode’ widget. Here, you’ll insert the shortcode you’ve created. For example, you can set the shortcode “.“
