How to use it
- Drop in the WebP files.
- If any of them have transparent areas, pick the colour those areas should become. White suits most uses.
- Download the JPGs.
Why so many downloads are WebP now
Most large websites serve WebP because it is noticeably smaller than JPG for the same look, which makes pages load faster. When you right-click and save, you get whatever the site served. Browsers are happy with WebP, but a lot of desktop software, older phones, print kiosks and government or school upload portals still only take JPG or PNG.
Picking the quality
The WebP you downloaded has already been compressed once by the website. Converting to JPG compresses it again, so there is no point going low: small artefacts from the first round get exaggerated by the second. The default of 92% keeps the result very close to what you saw in the browser. Drop to 80% only if the file size really matters.
What happens to transparency and animation
JPG has no transparency, so any see-through parts are filled with the background colour you choose. If you need to keep the transparency, convert to PNG instead. Animated WebP files will come out as a single still JPG of the first frame.

Questions people ask
Why does my WebP file turn black in some converters?
Transparent pixels in a WebP still store a colour value, which is often black. When a converter drops the transparency without filling it, that hidden colour shows. This page fills transparent areas with the background colour you pick.
Can I stop my browser saving images as WebP?
Not reliably. The site decides what format to send. Converting after download is the simplest fix.
Does WebP to JPG make the image bigger?
Usually, yes. WebP is more efficient, so the same picture needs more bytes as a JPG. A 40 to 80 percent increase is common at high quality.
