The WebP result is static and re-encoded at the selected quality, with compatible transparency preserved. A smaller file is not guaranteed; compare the downloaded result with the source.

Practical guide
Prepare JPG photographs as WEBP for a website
WEBP can re-encode JPG photographs with adjustable quality for web delivery. It restores neither detail nor transparency, so the change should be justified by measured size, appearance and support.
Start with an already compressed source
JPG already contains a lossy, opaque representation. WEBP keeps dimensions by default, but blocks, halos and detail removed from the source remain part of the image.
Match quality to publishing size
Compare texture, faces and gradients at the real display size. Lower quality may save bytes, but there is no fixed percentage and another encoding can expose new artefacts.
Confirm support across the delivery path
Check the browser, CMS, CDN and editing tools. Retain JPG as a fallback where WEBP is unsupported and test the full path before replacing every copy.
Avoid circular conversions
Output stays opaque and metadata is removed. Returning to JPG cannot recreate the first file, while repeated conversions only accumulate encoding decisions.
For reverse compatibility see WEBP to JPG; when AVIF is accepted, also compare JPG to AVIF from the same source.
Frequently asked questions
Can WEBP recover detail lost in JPG?
No. It only re-encodes available pixels and cannot reconstruct information discarded by JPG compression.
Will the WEBP have transparency?
No. JPG is opaque, and changing its container cannot create an alpha channel absent from the input.
Is WEBP always smaller than JPG?
No. Compare the actual content, quality and support before replacing the existing resource.
