Images have the power to give an attractive touch to your website. They help convey your website services and story, drawing visitors’ attention, creating better connections, and consequently, improving web traffic. Images make websites more compelling and contribute to the overall beauty of a website.

But, choosing the right type of image format to speed up your website often remains sceptical. Although there are dozens of image formats available, today we are going to talk about JPEG and PNG and what image format is best suitable for web pages.

For choosing between different image file types, probably your main concerns are clear image and fast loading speed. So, now, let’s first get an overview of JPG and PNG and their features.

Overview of JPG

JPEG stands for Joint Photographic Experts Group and is one of the most popular file formats used by websites. It was developed in 1992. Since JPEG file formats are lossy, they make large-sized images into small sizes and make them easy to load on websites. However, as the term “lossy” suggests that image resulted in quality reduction after compression.

Although this key feature of lossy compression in JPEG format is permanent, they are ideal to use for the web. Apart from this, JPEG is also helpful to contrast complex and vibrant colors of photographs in smaller sizes. It contains 16 million-plus different colors. In other words, JPEG lets you use large colorful pictures after compression.

So, if you are using an eCommerce website, JPEG image file format can be your best option. It will allow your website to load faster after making images lighter. As a result, it will reduce the overall loading time of the website but you won’t be able to get the same quality of the images.

So, if you have a large file, you can compress it down to turn it into a lighter JPG to achieve a goal of faster load time.

Features of JPG image format

• • smaller in size

• • fast loading speed

• • Lower image quality than PNG

• • Does not support transparency

• • Supported with a wide range of CMS platforms

• • Better for web pages with lots of images

Overview of PNG

PNG (pronounced as ‘ping’) stands for Portable Network Graphics and their compression is lossless. That means, your images will remain the same quality when they are compressed. However, using PNG for high-resolution photos means sacrificing your website loading time. 

PNG type of image format is best recommended for storing files with fewer colors like logos, illustrations, and screenshots. For photos, they are not an ideal option to go with as they consist of large files.

The PNG format allows crystal clear images with a quality display of letters, dark and light backgrounds, and sharp lines. PNG file type also provides a transparency feature which makes it a good choice for creating logos.

Features of PNGs image format

• • supports transparency

• • large file sizes

• • slow loading time

• • higher image quality

PNG vs JPG and What to Choose For Your Website?

After getting an overview of both the file types, we are now going to compare them based on their qualities. This PNG vs JPEG comparison is based on Compression, Size, and Transparency. 

Image Compression: JPEG is better than PNG

JPEG and PNG use different compression methods or codecs to store a file’s data.

JPEG works on the DCT (Discrete Cosine Transform) compression method. This technique splits an image into parts of different frequencies. As it is known that JPEG uses lossy compression, it eliminates the less important frequencies from an image.

While this method is efficient for large-sized images, there always be a certain loss of data.

Hence, JPEG images are most likely to have a quality drop but remain unnoticed by the viewers.

Whereas the case of PNG works on the no-loss data compression method named LZW (Lempel-Ziv-Welch) compression. As a result, this compression always keeps the quality of PNG images the same. 

PNG provides a near-perfect data representation even after compression, retaining the large size of the image. This makes JPEG image format better than PNG in terms of Compression.

Image Sizes of PNG vs JPEG

As we have discussed above, JPEG is a better option for colorful and real-life pictures. JPEG format keeps those photos smaller in size.

Therefore, JPEG has become the best choice for professional photographers.  

However, when color-filled images are allowed to save in PNG format, they may need more space and bandwidth to be saved.

On the other hand, PNG file sizes are suitable for illustrations, logos, screenshots, line art, etc to be saved in smaller size and better quality.

Image Background Transparency: PNG is the only option

The PNG image format is designed to support transparency in the images while JPEG doesn’t. This feature of PNG file format lets you overlay images using any background. It fits best over any background.

Most editing programs use a checked background to show the transparency of PNG images. This feature is great for logos.

JPG, on the other hand, does not provide transparent features and only supports non-transparent images.

Conclusion for PNG vs JPG

Identify your requirements and make the right selection. Depending on website purpose, Both the image file formats are better to choose from.

Do you want a fast-loading website? Which image format works best to get a fast website? In that case, we would suggest you go with JPGs for photos and PNGs for logos.

Incorporating such methods to add SVG files will make it possible to display two-dimensional images on WordPress sites.

In this article, we’ll cover the steps of uploading SVG files to your WordPress. To begin, let’s first understand what is SVG and how it works.

What is SVG?

SVG stands for scalable vector graphics, an image file format based on the XML markup language. While image formats like JPG or PNG are made up of pixels, SVG relies on a schema-like set of data which provides some great benefits. The major benefit of using SVG images in WordPress is that you can add large images while keeping the quality uncompromised.

The use of SVG images has been increasing, about 42% of all websites in 2024 are using SVG files. Also, SVG is supported by all major browsers.

How Does SVG Work?

Scalable vector graphics (SVG) produces two-dimensional vector images using XML. While JPG and PNG images are based on pixels, vector graphics use XML text.

That means JPG and PNG images start to blur when zoomed in, on the other hand, zooming in doesn’t affect the quality of the  SVG images.

So, vector graphics allow you to enlarge images without losing quality. Most importantly, SVG image file size is way smaller than JPEGs or PNG.

You can use SVG files in WordPress to design company logos, icons, or other graphics. Moreover, SVGs images can also be searched, indexed, scripted, edited, and compressed. However, SVG images are unsafe to use therefore WordPress doesn’t provide support for them by default.

Benefits of Using SVG on WordPress

Despite security issues with SVG, there are lots of benefits to using this image format on WordPress. Here are a few advantages of using SVG files:

• Scalability – SVG is a vector image format that keeps the quality the same across all screen resolutions. Even if you enlarge an image, the quality remains the same. Thus, it can be used for many purposes, making it a scalable format for many WordPress users. It is used, generally, for icons and logos.
• Smaller File Size – Since SVG files are scaled images, you can use them to improve website speed and performance. SVG images take less web storage space and load faster than raster images.
• SEO friendly – SVG files can be quickly indexed and appear on Google Image Search to help you make your website SEO-friendly. With raster images, you need to optimize images’ alt attributes.
• Code Based – SVGs can be edited and modified using a text editor or vector graphics editing software. You can optimize SVG image files for websites or add animations to make interactive graphics.  

How to Upload SVG files to WordPress Using 2 Safe Methods

There are two ways to add SVG files to your WordPress – using a plugin or manually. Since WordPress doesn’t support SVG by default, you’ll need to use these methods to get SVG support on the website.

Method 1: Adding SVG Using a Plugin:

Plugins make the process easier. So, to Upload SVG Files in wordpress, you can use the WordPress plugin. All you need to do is install the plugins, and configure a few settings to enable SVG support on WordPress.

Step 1: Download the plugin

First, you’ll need to download and install a plugin. We recommend using SVG support. Once you’ve installed and activated the plugin, move on to the settings > SVG support from the WordPress dashboard. There you’ll find the instructions to know how to style SVG files for your website.

Additionally, you’ll be able to configure a few important administrative settings. You can configure it to allow access to SVG upload restriction to administrators only. You’ll be able to upload SVG files directly to your media library. However, there are a few other important items to take care of first.

Step 2: Enable Gzip support of SVG files on your server

Enabling GZIP support for SVG files on your server will help you improve the response time of your website. If this file is added to your server, adding it to the list for your website will ensure that your SVG files are optimized quickly. Make sure to include this file type in your .htaccess file, in order for everything to run smoothly.

Step 3: Ensure that the plugin is Securing Files

The reason WordPress does not allow SVG files is the security issues. Since SVG files are XML based, your website becomes vulnerable to external entity attacks. So, it is recommended to limit SVG file uploading privileges to administrators only while configuring the SVG plugin.

You should also incorporate a more secured approach by ‘sanitizing’ your SVG files before you upload them. This will eliminate the unnecessary XML code which is highly prone to site attacks.

While the SVG support plugin doesn’t come with automatic sanitization, you can use another plugin to help with that, Safe SVG is one of them.

Method 2: Uploading SVG files to WordPress manually

If you don’t prefer using a plugin, you can manually Upload SVG Files in wordpress. Here’s how the process works:

Step 1: Edit the Functions.php file on your Site

Start with editing your website’s functions.php file. To do this, you can go to Appearance > Edit themes in your dashboard, and select the functions.php file.

Alternatively, you can also use an FTP application like Filezilla to access your site’s files. Whichever way you’ll choose, make sure to switch to a development environment before making changes to keep your live site safe from any harm.

Step 2: Add a code snippet

Open the functions.php file and paste the following code snippet in there.

function add_file_types_to_uploads($file_types){

$new_filetypes = array();

$new_filetypes[‘svg’] = ‘image/svg+xml’;

$file_types = array_merge($file_types, $new_filetypes );

return $file_types;}

add_filter(‘upload_mimes’, ‘add_file_types_to_uploads’);

Save changes once the code is successfully added, you’ll WordPress media library will be able to accept the SVG file for upload.

Final Words

Adding SVG images to WordPress using either of the methods adds up to many benefits. Unfortunately, SVG files are prone to code injection and external attacks, which makes them less reliable for WordPress support by default.

Keep in mind limiting upload privileges to the administrators so as to safely upload SVG files to the site’s media library.
