Why WebP for website photos
Images are the largest part of a typical home page by weight, according to the HTTP Archive Web Almanac 2025. WebP compresses them more efficiently than JPG, so you can keep the same visual quality and send fewer bytes, which helps both your visitors and your page speed scores. Every current browser shows WebP, so there is little reason to serve large JPG files anymore.
Size first, then format
A 4000-pixel-wide camera photo stays heavy in any format if the page shows it 1200 pixels wide. Resize the photos to the largest width they will appear at with the image resizer, then convert them here. If a platform does not accept WebP, the image compressor makes JPG files smaller while keeping the format. Keep your original JPG files, since converting back from WebP adds a second round of compression.
A simple workflow
- 1Resize your photos to their display width.
- 2Drop them here with the quality at 80, and check one or two at full size.
- 3Download the batch as a ZIP and upload the WebP files to your site in place of the JPGs.
Have PNG graphics too? The PNG to WebP converter keeps their transparent backgrounds.
Frequently asked questions
Does converting JPG to WebP make my website faster?
Usually, yes. Google measured lossy WebP images 25 to 34 percent smaller than comparable JPG images, and lighter images mean faster loading, especially on phones. Google's Lighthouse, which also powers PageSpeed Insights, flags images that could be smaller and suggests modern formats like WebP and AVIF.
What quality should I pick?
Around 80 is a good start for photos on a website. Look at a few images at full size: if you see blur or blotches in skin or skies, raise it to 85 or 90. Lower values save more bytes, but artifacts get easier to spot.
Can every browser show WebP?
Every current browser can display WebP, including Safari on iPhone and Mac. If you must support very old browsers, keep the JPG as a fallback.
Is the camera data kept?
No. The WebP contains only the picture, without EXIF data such as GPS location or camera model. For web images that is usually what you want.
Are my photos uploaded?
No. Your browser converts the photos on your device. To create WebP files, use Chrome, Edge or Firefox, because Safari cannot save WebP from a web page.
