How to convert JPG to WebP
Convert JPG photos to WebP for a faster website
Photos are usually the heaviest thing on a web page, and most of them are JPGs. WebP stores the same photo in fewer bytes, so swapping JPGs for WebP versions makes pages load faster without any visible change, which helps visitors on phones and slow connections most. Drop in up to 30 JPGs, download the WebP versions and upload those to your site in place of the originals.
For the best result, resize first. A photo that is 4000 pixels wide is still oversized as a WebP; scaling it to the width your layout actually shows, often 1200 pixels, and then converting gives the smallest file of all.
Converting does not change the dimensions: a 1200 pixel JPG becomes a 1200 pixel WebP. If your site resizes images itself, uploading lighter WebP files still saves storage and processing on every page view.
You can run the whole batch in one go and download a single ZIP.
How much smaller WebP photos are
At a similar visual quality, WebP photos are typically 25 to 35 percent smaller than the same JPGs. The exact figure depends on the picture: smooth skies, skin and soft backgrounds compress very well, while photos full of fine texture, like foliage or gravel, save a little less. Either way the saving adds up quickly on a page with many images.
The conversion here uses a quality setting chosen to look the same as the original on screen. The size of each WebP is shown next to the original size, so you can see the saving for every photo before you download.
Converting a JPG that has already been compressed heavily gives a smaller saving, because much of the detail WebP would encode efficiently is already gone. For the best results, convert from the original photos rather than from copies that have been saved several times.
On a typical blog post with ten photos, that saving can mean several megabytes fewer for every visitor, which is noticeable on a phone. Smaller images also reach the screen sooner, so the page feels faster even before it has finished loading.
Where WebP works and where to keep JPG
Every modern browser displays WebP, including Chrome, Safari, Firefox and Edge, and most website builders and content systems accept it. That makes WebP the right format for anything you publish online. Keep JPG for photos you send to people, print, or open in older software, because a few older apps and some email programs still do not open WebP files.
A simple rule: JPG for sharing and printing, WebP for the web. If you ever need a JPG back from a WebP, converting the other way takes the same few seconds.
Because the conversion runs in your browser, nothing is uploaded, which is useful when the photos are unreleased product shots or client work you are not allowed to share.
If your platform only accepts JPG, compressing the JPGs is the next best step: you keep the format and still make the files lighter.
