JPG to WebP

Why convert JPG to WebP

WebP is an image format made by Google for the web. A photo saved as WebP is usually smaller than the same photo as a JPG at a similar look, so pages load faster and use less data. That’s why many websites use it for photos, and why page-speed tests such as Google’s PageSpeed Insights suggest modern formats like WebP. For sending a photo to a person or a printer, a JPG is still the safer choice: more programs open it.

How to convert

1. Choose up to 30 JPG images, each up to 50 MB. You can also drop them on the box or paste one.
2. Leave the quality at 85, or change it (below).
3. Press Convert to WebP, then download each file, or all of them together as a ZIP.

Choosing the quality

The number, from 1 to 100, sets how much detail the WebP keeps. 85 is a good balance for photos on a website. Higher keeps more fine detail and makes bigger files; lower makes smaller files with softer detail. Each result shows its size, so you can compare it with the JPG and try another number if you need to. A JPG that has already been compressed hard won’t shrink much further: converting can’t recover detail, and a high setting may even make a slightly bigger file.

Safari, iPhone and iPad

Chrome, Edge and Firefox make WebP files themselves. Safari, and the other browsers on an iPhone or iPad that use Safari’s engine, can show WebP but can’t make it. When the page finds your browser can’t, it loads a WebP encoder of its own (libwebp, the reference WebP library) the first time you convert. It runs on your device, like everything else here, and your images still never leave it.

What else to know

• Size in pixels stays the same; for web pages, the Image Resizer can make big photos smaller too.
• Rotation and camera details: sideways phone photos come out upright, and camera details, GPS location included, aren’t copied.
• Names: photo.jpg becomes photo.webp. A file that can’t be read gets its own message, and the rest still convert.
