The majority of websites use images in JPEG or PNG formats, which have been in use since the 90s.
The emergence of a new mage format presents an opportunity to SIGNIFICANTLY reduce decrease your image file sizes. This format serves images in next-generation format that take advantage of advancements in image processing and compression. This new format is known as WebP.
This next-gen image formats offer superior compression and quality characteristics compared to older formats like JPEG or PNG.
WebP, serves as an excellent replacement for JPEG, PNG, and even GIF images. It also supports lossless compression, lossy compression, and animated images.
In the vast majority of cases, serving a WebP image can reduce image file sizes in the order of 50-80%.
Choose a next-gen format based on the range of browser/device support available. WebP is Google’s recommended next-gen format and is also the most widely used format with the best browser/device support.
To serve WebP images, use one of the following methods:
1. Manually convert your images to WebP format
There are multiple ways to do this manually, including:
A. Using an online WebP converter
You can manually convert your images to the WebP format using an online WebP converter. Note that this method is only recommended if youhave a few images to convert.
B. Using a Bulk WebP converter
For bulk conversion of images to the WebP format, consider using a Chrome extension like Bulk Images to WebP converter or using Android Studio for creating WebP images for mobile websites.
2. Use Photoshop
If you are familiar with Photoshop, you can use it to “save as” using the WebP format.
3. For WordPress (or other CMS users)
If you are using a CMS (e.g., WordPress), you can use of og many optimization plugins to serve WebP images on your website.
