How to Create WebP Images from JPG or PNG Images Using Irfanview
Recently, we wrote a post about an image format called “WebP”.WebP has been around for a few years but hasn’t been extremely popular because it was not supported by most browsers. But now, WebP is supported by almost every browser except for Apple’s Safari browser and the aging Internet Explorer.
The article generated a lot of interest. We’ve had several folks write and ask how to convert images to WebP format. So, we’re going to show you how to convert JPG and PNG images to WebP format using a free program called Irfanview.
First, if you don’t have Irfanview installed, download it from here. If you have a 64-bit computer, you can download the 64-bit version. If you’re not sure, download the 32-bit version. You can find out if you have a 32-bit or a 64-bit computer by following the instruction on that page. The chances are fairly good that you have a 64-bit PC.
Next, install Irfanview. After it is installed, open Irfanview and then open any JPG or PNG image.
After opening your PNG or JPG image, click on “File” > “Save as”…
In the “Save Picture As” dialog, next to “Save as type”, use the down arrow to select “WEBP Weppy File Format”.
Save your picture in WebP format.
Note: When you choose “WEBP” as the file format, you’ll get another dialog of options. But unless you have a reason to change these options, we suggest you leave these settings as they are.
That’s all there is to it!
Converting PNG / JPG images to WebP saves space. By using WebP format your image file sizes will be 25% to 30% smaller than the same image in JPG or PNG images with no noticeable difference in image quality.
Here is a JPG image with a file size of approximately 52 KB.
The same image in WebP format has a file size of approximately 39 KB, which results in a savings of about 25% with no loss of quality.
If you plan to use WebP images in your social media posts or web pages, keep in mind that Apple Safari and Internet Explorer cannot “see” .webp format. Safari may be able to “see” WebP soon. As for Internet Explorer -well, every dog has its day.
Also, you can convert any image format to WebP, but it works best with PNG and JPG images.
