Should I use WebP, PNG, or JPEG photos on my image format for the WordPress site? Images bring your content to life and improve the visual appeal of your WordPress website. However, selecting the appropriate file format is critical for performance.

If your photographs take a long load, your site will not deliver an optimal user experience. In this article, we’ll evaluate WebP, PNG, and JPEG image formats to help you choose the best one for WordPress.

WebP vs. PNG vs. JPEG – Introduction

Let’s first look at all 3 image formats and see how each of them works.

What Is WebP?

WebP, similar to PNG and JPEG, is a relatively new picture format. Google developed WebP, which delivers greater lossless and lossy compression for photos on the internet. This allows you to make smaller images, which improves page performance.

Lossless compression means that all of the data in the image remains after it has been expanded. On the other hand, Lossy compression reduces file size by permanently removing information from an image file.

One of WebP’s distinguishing features is its support for motion-based images, which is unavailable with PNG or JPEG. This makes WebP an excellent alternative to GIFs.

WordPress 5.8 added support for the WebP picture format. Previously, using WebP pictures in WordPress required the installation of a WordPress plugin.

All modern online browsers, such as Google Chrome, Firefox, Safari, and Edge, support the WebP image format. Many image editing applications support WebP and allow you to export images in this format.

WebP offers similar capabilities to PNG. WebP images have the same amount of transparency as PNG images.

Pros:

• Provides reduced file sizes compared to PNG and JPEG.
• Supported by popular web browsers.
• Get the same amount of visibility in images as PNG.
• Supports both lossless and lossy compression.
• Allows you to create motion-based graphics.

Cons:

• Converting photos to WebP format requires third-party software and plugins.
• Limited support from photo editing applications.

What is PNG?

Portable Network Graphics (PNG) is one of the most widely used picture formats on the Internet. It supports millions of hues, making pictures clearer and more lifelike.

The primary benefit of using PNG is its lossless compression algorithm. When an image is compressed, it loses neither data nor quality. This makes PNG an excellent format for your WordPress website if you require a smaller image file size while retaining fine details in the image.

Another advantage of using PNG is that it permits transparent backgrounds. That is why many website logos and other elements are in PNG format.

Here’s an example of a WPDruggy logo in PNG format.

Pros:

• It does not lose image quality when compressed.
• Has reduced image file sizes than JPEG.
• Provides high-quality image transparency.
• All major browsers and image-editing applications support this feature.
• Ideal format for logos and images with a little colour.
• supports lossless compression.

Cons:

• It does not support lossy compression.
• Limited colour depth, suitable for complex colour-rich images.

What is a JPEG?

JPEG, short for Joint Photographic Experts Group, is an image format created in 1986. It is the standard image format for various devices, including digital cameras and smartphones. Many WordPress website builders and image gallery plugins support JEPG images.

One of the advantages of using JPEG is that it produces colourful images with millions of colours. All web browsers support this format, and the image files are minimal.

Here’s an example of a butterfly image in JPEG format. It features many colours and details that aren’t as visible in other image formats.

JPEG is frequently the ideal format for complicated photographs with a lot of colours. The colours in the JPEG image above are vivid and stand out.

However, when optimized, you may detect a slight loss in image quality, particularly if the image has little colour data. Aside from that, JPEG photos are simply converted. You can convert them to any other format, including PNG and WebP.

Pros:

• It supports millions of colours.
• Excellent format for advanced, color-rich photos.
• Highly adaptable to other image formats.
• Supported by popular web browsers and image editing programs.

Cons:

• It loses image features after compression.
• It doesn’t support stacked images.
• There is no support for image transparency.

WebP vs. PNG vs. JPEG – Image File Size

When comparing WebP, PNG, and JPEG picture file sizes, a lot depends on the level of compression used when optimizing the image.

That being said, WebP lossless images are typically 26% smaller than PNG. Similarly, when comparing WebP and JPEG lossy photos, WebP images are 25-34% smaller.

For example, a Google Developers study reveals a considerable difference in image file size between JPEG and WebP formats.

This demonstrates that WebP images are significantly less in file size than PNG and JPEG. With a lower picture file size, you can improve WordPress performance and make your web pages load faster.

As a result, you’ll notice an improvement in WordPress SEO. Google uses page load speed as a ranking factor. If your site loads rapidly, you’ll have an advantage over slow-loading sites.

WebP vs. PNG vs. JPEG – Image Quality

The most effective image format for WordPress in terms of image quality will be determined by the type of website.

For example, if you are a photographer and post colour-rich images on your WordPress website, JPEG is the greatest image format to use. JPEG photos have a high compression ratio and help to preserve colour data.

On the other hand, if you’re publishing screenshots or individual photographs with few colours, you should use the PNG format. PNG produces high-quality images and works flawlessly with both complicated and basic graphics.

The WebP format is suitable for compressing photos on your website to maintain excellent performance. When comparing WebP with JPEG, WebP achieves approximately 30% greater compression than JPEG. We do not advocate using WebP if you have a photography or graphic design portfolio website.

What Is the Best Image Format for WordPress?

After comparing the pros and cons of WebP, PNG, and JPEG, the ideal image format is ultimately determined by your needs.

WebP is considered to be the future format, with all websites soon adopting it. When compared to JPEG, WebP produces the shortest image file size, saving storage space and improving website load speeds. However, be sure that your website builder or picture editing software supports the WebP format.

On the other hand, JPEG is the greatest image format for professional photographers and website owners who require colour-accurate photographs.

PNG is the ideal format for distributing screenshots and other images with minimal colour. It is a very adaptable format that produces high-quality photographs with a small file size.

Bonus Tips for Using Images in WordPress

images are essential components of your content, yet many website owners fail to include images of excellent quality in their blog posts and pages.

Aside from selecting the appropriate image format for WordPress, here are some pointers to help you create stunning photos and optimize them for performance:

Use Image Compression Plugins – Large graphics can slow down your website. To get faster performance, employ image compression plugins to optimize WebP, JPEG, and PNG pictures.

Add Image Alt Text: Alt text, often known as alternative text, is an HTML image tag that describes a picture. It lets search engine algorithms and screen readers interpret your images. When optimizing your website for SEO, use alt text in your photos to help them appear in image search results.

Choose the appropriate image size for your website. Beginners frequently struggle to determine which image size to use for their websites. Choosing the appropriate size ensures uniformity and a seamless user experience.

Use a Watermark or Disable Right Click – If you don’t want others to use your images without your permission, apply a watermark and disable right-clicking on them. For more information, visit our tutorial on how to prevent image theft in WordPress.

The Last Line

Finally, when choosing the optimal picture format for WordPress, consider both image quality and site performance. WebP is the most efficient format, providing superior compression without sacrificing quality, making it excellent for improving page load times.

PNG is best suited for images that require transparency or great resolution, but it creates larger files. JPEG is ideal for photographs or images with a lot of colours, as it combines high quality with modest file sizes. WebP is the ideal solution for an advanced WordPress site that prioritizes speed and performance. However, PNG and JPEG can still be beneficial in some situations.
