What Is WebP and Why Should You Use It?
WebP is a modern image format that delivers smaller files with the same quality. Learn when and why to convert your images to WebP.
If you run a website or work with digital images, you have probably heard of WebP. Created by Google in 2010, WebP is a modern image format designed to replace older formats like JPEG and PNG while delivering better compression and quality. In this guide, we explain everything you need to know about WebP and why it matters for you.
What Is WebP?
WebP is an image format developed by Google that uses advanced compression algorithms to produce images that are typically 25–35% smaller than equivalent JPEG files and 26% smaller than PNG files — without any visible loss in quality. It supports both lossy and lossless compression, transparency (like PNG), and even animated images (like GIF).
The format is now supported by all major web browsers including Chrome, Firefox, Safari, Edge, and Opera. This makes it safe to use on any modern website without worrying about compatibility issues.
Why Should You Convert to WebP?
- Faster page loads: Smaller image files mean your website loads faster. Google's own research shows that WebP images are 25–34% smaller than JPEGs of comparable quality.
- Better SEO: Page speed is a confirmed Google ranking factor. Faster sites rank higher in search results, which means more traffic and revenue.
- Lower bandwidth costs: If your website serves millions of images monthly, switching to WebP can cut your CDN and hosting bandwidth bills significantly.
- Transparency support: Unlike JPEG, WebP supports transparent backgrounds — just like PNG — while being much smaller in file size.
- Animation support: WebP can replace GIF for animations, producing files that are often 64% smaller than equivalent GIFs.
When Should You Stick With JPEG or PNG?
WebP is the best choice for web use in almost all cases. However, there are situations where JPEG or PNG might be more appropriate:
- Email clients: Many email clients do not support WebP yet. Stick with JPEG or PNG for email-embedded images.
- Printing: When you need the highest print quality, use TIFF or uncompressed formats.
- Legacy software: Older image editors and document tools may not support WebP. Always keep a JPEG or PNG backup.
