Why convert your images to WebP?
Images are usually the heaviest part of a web page. And weight directly affects load speed, the experience of mobile visitors and your Google rankings, which measure speed through the Core Web Vitals. Tools like PageSpeed Insights explicitly recommend “serving images in next-gen formats”.
WebP is that next-gen format: at the same visual quality, a WebP image is 25–35% smaller than a JPG and much smaller than a PNG, while still supporting transparency. Every current browser supports it, so you can use it on your site with confidence.
How to convert JPG or PNG to WebP
- Add your images: drag them onto the area above or tap “Choose files”. You can mix JPG and PNG.
- Adjust the quality. For photos on the web, 75–85% gives the best balance. For graphics with text, go up to 90%.
- Check the result: you'll see the original and new size of each image.
- Download the WebP files one by one or all together as a ZIP.
Benefits of WebP
- Faster pages and better PageSpeed scores.
- Less data usage for your mobile visitors.
- Transparency like PNG, with much lighter files.
- Less space on your hosting and in your backups.
Tips for optimizing images for the web
Format is only part of it. For an image to fly, also adjust its dimensions: there's no point uploading a 4000-pixel-wide photo that will be shown at 1200. Resize the image first, then convert it to WebP. If you need precise control over the final size, the image compressor lets you compare sizes.
If you use WordPress, Shopify or any other CMS, you can upload .webp files directly like any other image.
A note on Safari
Safari can display WebP images but can't create them from a web page. If you use Safari on Mac or iPhone and the option is unavailable, open this page in Chrome, Edge or Firefox. As always, your images are never uploaded.
How to use WebP on your website
On WordPress, Shopify, Wix or Squarespace, just upload the .webp file to the media library like any image. If you edit HTML by hand, you can use a regular <img> tag pointing at the .webp file. Always set the image's width and height to avoid layout shifts while it loads, and add a descriptive alt text, which also helps you rank in Google Images. With properly sized images in WebP, cutting a page's total weight in half is common.
