About the JPG to WebP converter
Swapping JPEG for WebP is one of the cheapest page-speed wins available: the same image at the same apparent quality, at roughly two thirds the bytes.
Support is universal in current browsers, so for web delivery there is very little reason not to.
The file is decoded, redrawn on a canvas and re-encoded by your browser. Nothing is uploaded, so there is no queue, no size cap imposed by a server, and no copy of your image left behind on someone else’s disk.
Picking a quality
WebP at quality 80 is roughly comparable to JPEG at 85 in perceived quality while being meaningfully smaller. The default of 82 is a good starting point for photographs on a website.
You are re-encoding an already lossy image, so avoid going very low — artefacts compound.
Frequently asked questions
Should I keep the original JPEG?
Yes, as a fallback source and as your master copy. Re-encoding from the JPEG each time compounds loss.
Is my image uploaded to a server?
No. The conversion runs in your browser using the canvas API. The file never leaves your device.
