Why convert JPG to WebP?

Convert JPG to WebP to make images load faster on a website or blog. WebP files are typically smaller than JPG at similar visual quality, which helps page speed, and all current major browsers display WebP.

Quality setting: WebP is lossy, so use the quality slider to trade file size against sharpness. 85–90% is a good default for photos.

JPG vs WebP

JPG (also written JPEG) is the most widely supported image format. It uses lossy compression, which keeps photos small by discarding detail the eye barely notices, but it has no transparency.

WebP is a format developed by Google that supports both lossy and lossless compression plus transparency. WebP images are typically smaller than equivalent JPG or PNG files, and all current major browsers support them, but some older software, editors, and upload forms still do not accept WebP.

Frequently asked questions

How much smaller is WebP than JPG?
It varies by image, but WebP files are often noticeably smaller at similar visual quality. Compare the before and after sizes shown for each file.
Will WebP images work everywhere?
All current major web browsers support WebP. Some older software, email clients, and upload forms do not, so keep a JPG copy if you need maximum compatibility.
What quality should I choose?
Start around 80–90% and check the result. Lower values give smaller files with more visible artifacts.
