WebP typically stores the same photo in 25–35% fewer bytes than an equivalent-quality JPG. On a page carrying a dozen images that's a real cut to total page weight, which is why converting to WebP is one of the most common fixes for a slow Largest Contentful Paint score.
Support is no longer a concern: every current browser reads WebP, including Safari since version 14. The usual pattern is to serve WebP as the default and keep a JPG fallback only if you still need to support genuinely ancient clients.
Conversion runs entirely in your browser at high quality, so your photos never touch a server. That matters if you're preparing client work or unreleased product shots for a site.

Smaller images, same picture
WebP typically produces files 25–35% smaller than JPG at visually equivalent quality. On a page carrying a dozen photographs that is the difference between a site that feels instant and one that does not, particularly on a phone connection.
Page speed is a ranking factor and a conversion factor, and images are almost always the heaviest thing a page loads. Converting them is usually the single largest speed improvement available without touching any code.
Browser support in practice
Every current browser supports WebP — Chrome, Edge, Firefox, Safari and the mobile versions of all of them. It is a safe default for the web today.
Off the web it is patchier. Older desktop software, some photo viewers and many upload forms still reject it, so keep the JPG originals for anything you will email, print or upload elsewhere.
Where converting pays off
- Website and blog images
- Faster loads and better Core Web Vitals with no visible change to the pictures.
- Product catalogues
- Large image sets where a third off every file compounds into real bandwidth savings.
- App and email assets
- Smaller payloads wherever images are being fetched over a network.

Frequently asked questions
How much smaller will my images get?
Usually 25–35% smaller than the JPG at comparable quality, though it varies with the picture — detailed textures compress less than flat areas.
Do all browsers support WebP?
Yes. Chrome, Edge, Firefox, Opera and Safari 14+ all display WebP, which covers effectively every browser in current use.
Will converting reduce quality?
We encode at 92% quality, which is visually indistinguishable from the source for photos. Because your JPG was already lossy, avoid repeatedly re-converting the same image between formats.
Is WebP good for SEO?
Indirectly. Smaller images load faster, and page speed — particularly Largest Contentful Paint — is a Core Web Vitals signal Google uses in ranking.
Can I convert several at once?
Yes. Add up to 20 JPGs and they convert in one batch, downloadable individually or as a single ZIP.
Are my images uploaded?
No. The conversion happens in your browser, so your images never leave your device.
