What are WebP files and how to open them online? 


For a seamless online experience, companies are spending countless hours developing better technologies. WebP files are one of them.

You must already be familiar with PNG and JPG file formats for images, and you must also already know that image optimization is also a crucial factor in Search Engine Optimization (SEO). WebP is a fairly recent file format for images, which will change the quality game for images on websites.

Today you’ll learn more about WebP files, their benefits, and the online proofing platform you can use for them.

So let’s dive right into it!


What is a WebP file?

WebP is another file format for images. But a single sentence won’t be enough to define what this means. So what are WebP files for real?




Like everything else online, let’s start with Google. We all know that image optimization is an important factor that affects a website’s page speed. A problem that most developers face here is that using a high-resolution image will slow the site, but if they use low resolution, it will lead to a poor user experience.

A real paradox we got here. Since Google is the one setting up tricky guidelines, they should also be the one resolving them, and that’s what they did by introducing the .webp format for images. 

With a WebP file format, you won’t have to sacrifice your image quality for smaller file size. WebP files are designed to make your page speed faster by incorporating high-quality images with a smaller file size on your web pages.


What are the benefits of using WebP files?

That was a simple and short introduction. If you were unaware of WebP files, now you know. And you should start using them as well because they have much more to offer.

Of course, PNG and JPG both have their perks, but you should also know the advantages of using a WebP file.



1. It offers versatility  

Google did not actively come up with the idea of developing WebP files; it was a spontaneous decision they made while testing WebM files – an open-source video format. 

However, the quality WebP images have over other formats is that it was made by combining the distinct qualities of JPG, PNG, and GIF formats. This means no matter how, where, or why you use them, WebP images will be more versatile than any other format.

2. Compatible with most software and applications 

Although, after its initial release, many browsers refused to support WebP files, many of them have already adopted this new image format for their latest versions, including Opera, Firefox, and Chrome (obviously). Safari is still yet to acknowledge this format, but by the looks of it, it might happen any time soon.

3. Easy file sharing 

We all understand the importance of efficient file sharing as developers, creators, and business owners. Nobody wants to see an error popping up or distorted image quality when sending images for their creative or marketing projects.

With WebP format, an open-source codec, all types of images are accessible within a few seconds, from any browser and in their actual resolution. Since this file format is supposed to be efficient, you can count on it to keep your images safe from distortion and accurate in terms of color and pixel quality.

4. High quality 

Talking about accurate colors and high pixel quality, let’s extend a bit more on that. WebP files offer lossy, lossless, and translucent image compression retaining the image’s original quality.

The format uses predictive compression to encode an image; it checks the values of neighboring pixels and predicts them in a complete block. After determining the difference, it only encodes and removes the redundant data from the file, reducing its size and ensuring good resolution.

5. Optimization 

WebP lossless images compared to PNG and lossy images compared to JPG is between 25 – 34% smaller in size and maintain an equivalent image SSIM quality index. In simpler terms, if you’re using WebP files, your page will load 3× faster and look better simultaneously.
