When WebP is useful
WebP is useful for web delivery when the destination accepts it. Conversion preserves pixel dimensions and may reduce bytes, but a detailed or already optimized JPG can occasionally produce a larger result.
- Changing format cannot restore source detail.
- Check destination compatibility before replacing a JPG workflow.
- Conversion stays in the browser.

Does JPG to WebP reduce quality?

Will WebP always be smaller?
No. Content and prior optimization affect the measured result.
Is the photo uploaded?
No. Conversion happens in your browser.
