What is WebP?
WebP is a modern image format developed by Google. It supports both lossy compression (like JPG) and lossless compression (like PNG), as well as transparency and animation. Its main advantage is size: according to Google’s own comparisons, lossy WebP images are typically 25–34% smaller than comparable JPGs, and lossless WebP images are around 26% smaller than PNGs.
All major browsers support WebP, including Chrome, Edge, Firefox and Safari, which makes it a safe choice for websites today.
Why convert images to WebP?
Images are usually the heaviest part of a web page. Serving WebP instead of JPG or PNG reduces the amount of data each visitor downloads, so pages load faster, especially on mobile connections. Faster pages improve user experience and Core Web Vitals, which Google uses as one of many signals in search rankings.
- Use quality 75–85% for photos on websites.
- Use quality 90%+ for product photos where detail really matters.
- Convert PNG graphics with transparency to WebP to keep the transparent background at a smaller size.
Why convert WebP to JPG or PNG?
When you save an image from a website, it is often a WebP file. Some older programs, printing services, document editors and upload forms still don’t accept WebP. Converting to JPG makes the image universally compatible. Choose PNG instead if the image has a transparent background or contains sharp text and lines.
Which format should I choose?
| Format | Choose it when |
|---|---|
| WebP | The image is for a website or app and you want the smallest file |
| JPG | You need maximum compatibility for photos (email, print, forms) |
| PNG | You need transparency or pixel-perfect graphics in any app |
A note on browser support
Creating WebP files relies on your browser’s built-in encoder. Chrome, Edge, Firefox and other modern browsers support it. If your browser cannot create WebP, the WebP option is disabled and you can still convert to JPG or PNG.
