Converting JPG to WebP is a common web image optimization: smaller files at similar quality and faster page loads. This guide explains how to convert and how to choose quality.
Why is JPG to WebP smaller?
The WebP compression algorithm is more efficient than JPG, typically shrinking size by another 20%–35% at similar quality.
For image-heavy websites, switching everything to WebP often brings a significant speed boost and bandwidth savings.
How to choose the quality parameter?
The web default of 80–90 quality balances size and quality well.
For quality-sensitive content, use 90 or above; for size-sensitive cases (like thumbnails), dropping to around 70 is fine.
After conversion, the tool shows the original size, output size, and savings percentage, so you can adjust the parameter accordingly.
What about compatibility?
All modern browsers support WebP, but if the file will be sent to someone on older software or an older system, WebP may not open — confirm beforehand.
