Why WebP for the web
Every photo on a page has to download before visitors can see it. WebP usually stores photos in fewer bytes than JPG at comparable visual quality. Pages load faster as a result, which you notice most on a phone with a weak connection. That’s why PageSpeed Insights flags large JPGs and suggests modern formats like WebP.
All current browsers display WebP. WordPress has accepted WebP uploads since version 5.8, and many shop systems and site builders handle the format too.
How much smaller will it get?
There’s no fixed number. It depends on the subject, the image dimensions and how heavily the JPG was already compressed. The results list shows the new size of every file. If the WebP is barely smaller, or even larger, the JPG was probably compressed hard already. In that case, lower the quality a little or keep the JPG.
Start from the original
JPG and WebP are both lossy, so converting compresses the image a second time. Use the original from your camera or phone if you can. A JPG that has been edited and saved several times has already lost quality. Quality 85 keeps photos clean for the web in almost every case. For large header images, try a slightly lower value and compare the results on screen.
What happens to photo data
The WebP contains no EXIF data. Capture date, camera model and GPS location won’t end up on your website, which is usually what you want when publishing. It also makes the result a poor archive format, since the capture date is gone. Hold on to your original JPGs.
Phones often record portrait orientation only as an EXIF flag. The converter rotates the pixels first, so your WebP doesn’t end up lying on its side.
Formats and limits
Good to know
- This page expects JPG and produces WebP. PNG, WebP and HEIC files are accepted as well.
- WebP quality defaults to 85. The slider goes from 1 to 100 and applies to every file you add after changing it.
- Photos in wide color spaces such as Display P3 are converted to sRGB. Very saturated colors may look slightly flatter as a result.
- EXIF orientation is applied to the pixels. All other EXIF data, including GPS, is left out of the WebP.
- Each image can have up to 50 megapixels, or up to 16 megapixels on iPhone and iPad. Larger images are rejected with a notice.
- All converted images together can be up to 512 MB, or up to 192 MB on iPhone and iPad. The same limit applies to the ZIP file.
How much smaller will my photo be as WebP?
That depends on the image, so there's no honest percentage to promise. Check the size in the results list. If the WebP isn't noticeably smaller, lower the quality a bit or stick with the JPG.
I changed the quality, but the result looks the same. Why?
The slider applies to files you add after changing it. Images that are already converted stay as they are. Just add the photo again.
Can I upload WebP images to WordPress?
Yes, WordPress has supported WebP since version 5.8. For WordPress to generate resized versions, the image library on your server has to support WebP as well.
Does this work on an iPhone?
Yes. If your browser can't create WebP files itself, which is currently the case with Safari, the converter loads its own WebP encoder for the first image. That encoder runs on your device too, so the first image just takes a moment longer.
Should I convert my photo library to WebP?
Probably not. You'd lose the capture date, camera details and location, and every extra round of compression costs some quality. WebP is meant for images that appear on a website. Keep your originals as JPG.
