Will the WebP look worse than the JPG?

At 80% or above most people cannot see a difference. Compare both at full size if the image will be shown large.

Should I keep the original JPG?

Yes. Keep originals for editing and printing, and use the WebP copies on your website.

Is the conversion private?

Yes. The HTML5 Canvas API converts the image locally, so nothing is uploaded to a server.

Will converting to JPG lose quality?

JPG and WebP are lossy. Use the quality slider (90%+ is visually near-identical). PNG is lossless but larger.

What happens to transparency?

JPG has no transparency, so transparent areas are filled with a colour you choose (white by default). PNG and WebP keep transparency.

Which format should I pick?

Use PNG for logos and screenshots, JPG for photos, and WebP for the smallest web-ready files.

About JPG to WEBP

When to use it

Swapping JPG photos for WebP is a quick way to cut page weight with little visible change.

What to know

Both formats are lossy, so each re-encode can add artefacts. Convert from the original JPG, not an already converted copy.

Pro tip

Quality around 80% often looks the same as the JPG at a smaller file size.

JPG to WebP: same photo, smaller file

Converting JPG photos to WebP cuts file size with little visible change, which helps page speed, hosting costs and mobile data use. At about 80% quality, a WebP is often a third smaller than the JPG it came from.

Always convert from the best original you have. Both formats are lossy, so converting a JPG that has already been compressed several times stacks the artefacts. Starting from a camera original or a high-quality export gives the cleanest WebP.

The conversion runs on your device with the browser canvas, so even large batches of photos are never uploaded. Metadata such as camera model and GPS location is removed in the process.
