Why WebP for your website

Images are usually the heaviest part of a web page, and page speed is part of how Google judges a page’s experience. WebP stores the same picture in noticeably fewer bytes than JPG, so converting a site’s photos is one of the simplest ways to make it load faster — for an online shop with hundreds of product photos, the saving adds up quickly.

Smaller still

If the photos are bigger than they are ever shown, resize them first: a 4000-pixel photo shown 800 pixels wide wastes most of its bytes whatever the format. The bulk image editor resizes and saves as WebP in one pass, and AVIF — available in the same converter — is usually smaller again, at the cost of slower saving.

Other conversions

This page is the bulk image converter opened on WebP. For graphics with transparency there is PNG to WebP, and to go back the other way, WebP to JPG.

Frequently asked questions

How much smaller is WebP than JPG?
Typically 25–35% smaller at the same visual quality, according to Google’s own comparisons; it varies with each photo. Every row shows the size before and after, so you see the saving on your own images.
Do all browsers show WebP?
Yes — every current browser, including Safari, shows WebP. Some older desktop software and some upload forms still do not accept it, so keep the JPGs if a file has to go somewhere other than a website.
Which quality should I choose?
The default, 82%, looks the same as the original on a screen and is the usual choice for websites. Lower it for thumbnails and backgrounds; raise it for photography portfolios.
Are my images uploaded?
No. The conversion runs in your browser; the images never leave your computer. That is why there is no account and no limit on how often you use it.
