The format

About JPG and WebP

WebP is a modern image format Google introduced in 2010 to be a smaller, more efficient alternative to JPG. For photographic content it compresses roughly 25-35% better at the same perceived quality, which is exactly why Lighthouse keeps nagging you to adopt it. Converting JPG to WebP is the single easiest way to speed up an image-heavy website or app without visibly degrading quality. Because the entire conversion runs inside your browser via Canvas, nothing is uploaded, nothing is logged, and large batches don't wait in a queue — your own device is the compute.

The questions

Frequently asked

How much smaller will my file be?

Typically 25-35% smaller than the source JPG at default (85%) quality, with no visible difference. On already-highly-compressed JPGs the saving may be less, but it is almost always a reduction.

Where does WebP work?

All modern browsers (Chrome, Safari 14+, Firefox, Edge), most CMSes (WordPress, Shopify, Webflow), and native apps on recent macOS, iOS and Android. Older software like Photoshop CS6 or legacy Office won't open WebP.

Will quality drop?

Not visibly at the 85% default. WebP is designed to match or beat JPG quality at the same perceptual level while using less space.

Why would I convert JPG to WebP?

Smaller files mean faster-loading websites, happier Lighthouse scores, cheaper CDN bills, and quicker uploads to messaging apps that don't re-compress.

Are my files uploaded?

No. The browser's Canvas API decodes and re-encodes each JPG locally. No file ever reaches our servers.

Can I batch convert?

Yes. Drop multiple JPGs — each is converted locally and downloaded individually or as a single .zip.
