What is JPG (JPEG)?
The most widely used photo format, with lossy compression. Photos, email, social media.
What is WebP?
A modern Google image format – smaller files than JPG and PNG. Website images, faster page loads (SEO).
When to choose JPG to WebP
WebP was designed for web pages: the same image is usually noticeably smaller than a JPG, so pages load faster. If you run a website or shop with many photos, this is one of the simplest ways to cut the amount of data transferred.
Common problems and fixes
- An older program or email client will not open WebP – current browsers support it, but some old editors and print-shop systems do not. In that case keep the JPG.
- Quality looks worse – raise the quality slider. Converting from an already compressed JPG adds a new loss on top of the old one.
- The file did not shrink – an already heavily compressed JPG may shrink only a little.
Quality tips
Try a few quality values and compare the result with the original before uploading to a site. Whenever possible, convert from the original rather than a picture that has already been re-compressed.
