Method 1 Using HTML to Add an Image Icon

Code Example

HTML Image Icon Example

<button>
  <img src="https://img.icons8.com/ios-filled/16/000000/star--v1.png" alt="Star Icon" style="vertical-align:middle;">
  Favorite
</button>

Code Explanation

<button>
  <img src="https://img.icons8.com/ios-filled/16/000000/star--v1.png" alt="Star Icon" style="vertical-align:middle;">
  Favorite
</button>

This is a simple button that uses a website URL image source for "star--v1.png". You can also use a local image source like this: <img src="icon.png">. The alt attribute describes the image, and the style and button text (like "Click Me") can vary.

Note: You don’t have to add styles directly to the button. However, it's best practice to always include the alt attribute for accessibility (screen readers) and in case the image fails to load. For cleaner, more maintainable code, we recommend applying styles via CSS instead of inline.

Method 2 Using CSS to Add an Image Icon

Code Example

CSS Image Icon Example

--HTML--

<button class="icon-btn">Click Me</button>

--CSS--

.icon-btn {
  background: url('https://img.icons8.com/ios-filled/16/000000/star--v1.png') no-repeat left center;
  padding-left: 24px;
  height: 32px;
  background-size: 16px 16px;
}

Code Explanation

<button class="icon-btn">Click Me</button>

This is a simple HTML button with a class name of "icon-btn". Let's make sure the CSS code has the same class name. The text "Click Me" will appear on the right side of the HTML button. Remember to separate HTML from CSS code in your favorite code editor like JSFiddle.

.icon-btn {
  background: url('https://img.icons8.com/ios-filled/16/000000/star--v1.png') no-repeat left center;
  padding-left: 24px;
  height: 32px;
  background-size: 16px 16px;
}

Good, the CSS code begins with the correct class name ".icon-btn". Pay attention to the URL, it calls the image icon to appear on the left side of the HTML button. The icon is a PNG image named "star--v1.png". The rest of the code padding, height and background size are all standard CSS styling.

Method 3 Using JavaScript to Add an Icon

Code Example

JavaScript Image icon Example

--HTML--

<button id="js-btn">Click Me</button>

--JavaScript--

  const btn = document.getElementById('js-btn');
  const img = document.createElement('img');
  img.src = 'https://img.icons8.com/ios-filled/16/000000/star--v1.png';
  img.alt = 'Icon';
  img.style.width = '16px';
  img.style.height = '16px';
  img.style.verticalAlign = 'middle';
  img.style.marginRight = '6px';

  btn.prepend(img);

Code Explanation

<button id="js-btn">Click Me</button>

This is the HTML button with an ID name of "js-btn". As you can see, the image icon will appear to the right of the button text named "Click Me".

  const btn = document.getElementById('js-btn');
  const img = document.createElement('img');
  img.src = 'https://img.icons8.com/ios-filled/16/000000/star--v1.png';
  img.alt = 'Icon';
  img.style.width = '16px';
  img.style.height = '16px';
  img.style.verticalAlign = 'middle';
  img.style.marginRight = '6px';

  btn.prepend(img);

JavaScript code is a bit more advanced, so we’ll keep it simple for now by focusing on how to call an image icon.

First, make sure the button is selected correctly with `const btn`, which targets the element with the ID `"js-btn"`.
Then, `const img` creates a container (a variable) to hold the new image element.

Next, `img.src` sets the source of the image — in this case, a PNG file named `"star--v1.png"` from a website URL. That image is now stored inside the `img` container.

The rest of the JavaScript code sets the image’s description (`alt`) and styles like size and alignment.

Tools and Resources

To add image icons to HTML buttons, you’ll need a few accessible tools. First, a text editor like Notepad (free on Windows) or Visual Studio Code (free, downloadable from code.visualstudio.com) is essential for writing and editing HTML files.

For image icons, free resources like the Flaticon website (flaticon.com) or Icons8 (icons8.com) offer thousands of icons in formats like PNG or SVG, perfect for buttons. Use an image editor like Canva (canva.com, free plan available) or GIMP (gimp.org, free) to resize or customize icons if needed.

A web browser like Chrome or Firefox lets you test your buttons instantly. For hosting icons, free image hosting sites like ImgBB (imgbb.com) are great for testing, while a server or content delivery network (CDN) is ideal for live websites.

Beginners can start with these free tools, available online, to experiment without cost. Save your HTML file with a .html extension, and store icons in an accessible folder or URL. These resources are beginner-friendly, ensuring you can start creating professional-looking buttons today.

Are there standard icon dimensions?

Yes, standard icon dimensions for HTML buttons are typically 16x16, 24x24, or 32x32 pixels. These sizes ensure icons are clear without overwhelming the button. For high-resolution displays, consider 48x48 pixels or SVG icons, which scale without losing quality.

Use tools like Canva or GIMP to resize icons, keeping them proportional to avoid distortion. Consistent sizes create a polished look, making buttons user-friendly and visually balanced across your website. Should icon images be hosted on the web or our server for best performance?

Hosting icon images on your server is best for performance, as it reduces reliance on external sites and ensures faster load times. Use a content delivery network (CDN) for even better speed and reliability.

For testing, web-hosted icons from sites like ImgBB are fine, but they may load slower or fail if the host is down. Optimize images (under 100KB) and store them locally for live websites to guarantee consistent, quick performance and a seamless user-experience.

Can I use free image icon URLs for learning or testing?

Yes, free image icon URLs from sites like Flaticon or Icons8 are great for learning or testing. They provide easy access to PNG or SVG icons without cost, perfect for practicing button design. However, for live websites, check licensing terms—some free icons require attribution or have commercial use limits.

For professional projects, consider hosting icons on your server to avoid broken links or slow loading, ensuring reliability while you refine your coding skills.

What file types work best for button icons?

PNG and SVG are the best file types for button icons. PNGs are widely supported, offering transparency for clean designs, but can pixelate if resized. SVGs are ideal, as they scale without losing quality, perfect for responsive websites.

Both are lightweight when optimized, ensuring fast load times. Avoid JPEGs, as they lack transparency and may look blurry. Use tools like Icons8 to download these formats, and compress files to keep your buttons sharp and your site fast.
