When to use JPG to WebP
WebP is supported by modern browsers and can reduce photo size for websites. Converting from JPG re-encodes the image, so fine detail may change; compare the result before replacing the original.
Quality and file size
A WebP result is not guaranteed to be smaller than its JPG source. This tool checks whether the browser can encode WebP and stops with a clear message if it cannot.
Frequently asked questions
Will WebP always be smaller than JPG?
No. The size depends on image content and the browser encoder.
Does conversion change image quality?
WebP encoding is lossy here and may change fine detail. Keep the JPG original.
What if my browser cannot encode WebP?
The tool detects this and disables conversion with a message to use a supported browser.
Are my photos uploaded?
No. Decoding and encoding happen in this browser tab.
