80–85% looks the same as the JPG for most photos, at a much smaller size.
How do I convert JPG to WebP?
Select or drop your JPG files and each one is converted to WebP at the quality you choose; 85% suits most photos. The tool shows the actual saving for each file. Safari, and most browsers on iPhone and iPad, can’t create WebP, so convert on a computer or an Android phone.
- Set the WebP quality. 80–85% keeps photos looking the same as the JPG at a smaller size.
- Select or drop one or more JPG or JPEG files. Each one is converted as soon as it is added, with its size before and after.

How much smaller is a phone photo as WebP?
Converting a 12-megapixel photo taken on an iPhone 14 (4032 × 3024 pixels, 3.7 MB) at the default 85% quality gave a 1.86 MB WebP in Chrome: 50% smaller than the JPG, at the same 4032 × 3024 pixels. The phone had saved the original at high quality, so there was more to remove than in a typical web JPG.
Is WebP always smaller than JPG?
Usually, but not always. Google’s own comparison found WebP files 25–34% smaller than JPGs of similar quality. When a JPG has already been compressed heavily, converting it at a high WebP quality can save little, or even make the file larger. Lower the quality a little, or keep the JPG, if that happens.
Converting never brings back detail the JPG already lost, so start from the best copy of the photo you have.
Where WebP works
Every current major browser can display WebP, so it is safe for websites. Some older desktop software, email programs and upload forms don’t accept it; for those, keep the JPG.

Frequently Asked Questions
Why can’t I convert in Safari?
Safari can show WebP images but can’t create them, and most browsers on iPhone and iPad use Safari’s engine, so they can’t either. Convert on a computer or an Android phone with Chrome, Edge or Firefox.
Does WebP support transparency?
Yes, but a JPG has no transparent areas, so the WebP won’t either. To make other images smaller while keeping transparency, use the PNG to WebP converter, which keeps it.
Should I use WebP for upload forms?
Only if the form lists WebP. Many application portals accept only JPG or PNG; for those, use the compress-to-size tools instead.
