The saving is consistent
WebP's lossy compression is meaningfully more efficient than JPEG's, delivering roughly 25 to 35 percent smaller files at equivalent perceived quality. On an image-heavy page that is one of the cheapest performance wins available, because nothing about the layout or code has to change.
Two lossy encodes in sequence
Converting an existing JPEG re-encodes content that was already lossy, so a second round of loss occurs. It is usually invisible at quality 80 to 85, but it is real. Where you still have the original camera file or design export, encode WebP from that rather than from the JPEG, and the result is both smaller and cleaner.
Do not raise the quality to compensate
A common mistake is converting at quality 95 to avoid loss, which produces a WebP larger than the JPEG it replaced. That defeats the entire purpose. Quality 80 to 85 preserves the appearance and delivers the saving.
Serve both, do not replace blindly
The robust pattern is a picture element with a WebP source and a JPEG fallback, so any client that cannot handle WebP still gets an image. In practice every current browser handles WebP, but the fallback costs nothing and covers feed readers, older email clients and unusual user agents.
Metadata is dropped
Browser-based conversion strips EXIF, including camera model, timestamp and GPS coordinates. That is usually desirable before publishing. If you need copyright or attribution metadata preserved, use a tool that carries EXIF across, because this conversion will not.

Frequently Asked Questions
How much smaller is WebP than JPEG?
Typically 25 to 35 percent at equivalent perceived quality. On an image-heavy page it is one of the cheapest performance improvements available, since nothing else has to change.
Does converting an existing JPEG lose quality?
A second round of lossy encoding occurs, usually invisible at quality 80 to 85. Where you still have the original camera file or design export, encode from that instead for a smaller and cleaner result.
Should I use a high quality setting to be safe?
No. Converting at quality 95 often produces a WebP larger than the JPEG it replaced, which defeats the purpose. Quality 80 to 85 preserves appearance and delivers the saving.
Do I still need a JPEG fallback?
Every current browser supports WebP, but a picture element with a JPEG fallback costs nothing and covers feed readers, older email clients and unusual user agents.
Is EXIF metadata preserved?
No. Browser conversion strips it, including camera model, timestamp and GPS location. That is usually desirable before publishing, but use a different tool if you need copyright metadata carried across.
