A heavy PNG photo
In our test, the 3.4 MB PNG header photo of a café website became a 312 KB WebP that looks the same on the page. As a BMP the same photo was 6.2 MB, as a GIF 1.5 MB.

The same photo as a quality-85 JPEG went from 397 KB to 303 KB. JPEGs gain less, and one that was squeezed very hard may stay about the same size.
PNG, JPEG, AVIF, GIF, BMP and SVG, plus other pictures Chrome can show.
The item sits in Chrome's own image menu. No new tab, no upload site, no editor.
Lossy WebP at quality 85, tuned for websites: the picture looks the same and the file gets lighter. Nothing to tune.
Transparent logos, icons and product cut-outs stay transparent, at a fraction of their old size.
cafe-hero.jpg becomes cafe-hero.webp, ready to upload to your site.
The conversion runs in Chrome on your computer. Your pictures never go to a server.
PageSpeed reports have long told site owners to “serve images in next-gen formats”. WebP is one of them: every current browser shows it, and at the same look it is usually far lighter than PNG, GIF or BMP and lighter than most JPEG photos. Lighter pictures mean faster pages.
Getting a WebP usually means an online converter: save, upload, wait, download, rename. Save image as WEBP does it from the page with the picture: one right-click, and a lighter copy with the original name lands in Downloads. The output is always lossy at quality 85; if you need an exact copy, keep the original.
Pictures are converted in Chrome on your computer. No server of ours ever sees them.
No analytics, no account. We don't know what you save.
The menu item on pictures, downloads to save the file, reading the picture you clicked (through the page when it needs your login), a hidden page that draws SVG, and local storage for the rating reminder.
| An online converter vs Save image as WEBP | “Save image as” + an online converter | Save image as WEBP |
|---|---|---|
| Steps to get a WebP | Save, upload, wait, download, rename | One right-click |
| Where your picture goes | To the converter's server | Nowhere: it stays on your computer |
| Quality | Usually a slider to choose | Fixed at 85, nothing to tune |
| File name | Depends on the converter | The picture's own name, .webp |
| Price | Often free, with limits or ads | Free, no account |
Add Save image as WEBP to Chrome, right-click the picture and choose “Save image as WEBP”. The file lands in your Downloads folder as a .webp, whatever format the site used.
Right-click the picture on the page and choose “Save image as WEBP”. The conversion runs in your browser: nothing is uploaded, and there is no queue.
It depends on the source. In our test a 3.4 MB PNG photo became 312 KB (91% lighter), a GIF 78% lighter and a quality-85 JPEG 24% lighter. A JPEG squeezed very hard may stay about the same.
No. The extension always writes lossy WebP at quality 85, tuned for websites. If you need an exact copy, keep the original file.
Yes. Transparent areas in PNG, GIF, SVG and other pictures stay transparent in the WebP.
Yes. An animated GIF becomes a still WebP of its first frame. SVG graphics are drawn at their own size, then converted.
Yes. If a picture only loads while you're signed in, the extension reads it through the page you have open. Pictures made by web apps (blob: and data: links) work too.
