JPG to WebP Converter

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.
