or — multiple files welcome. Nothing is uploaded; conversion happens on your device.
Files are processed entirely in your browser — never uploaded, never stored. Large photos convert in about a second each; the first HEIC file loads a small decoder module.
How it works
Swapping JPGs for WebP is typically a 25–35% size cut at identical visual quality — one of the last easy page-speed wins on image-heavy stores and blogs.
- Drop your JPGs above.
- Keep quality at 85% for a like-for-like conversion, or lower it to compress and convert in one step.
- Download and replace on your site; keep JPG copies for email, which still handles WebP poorly.

Frequently asked questions
How much smaller is WebP than JPG?
Typically 25–35% smaller at equivalent visual quality. On an image-heavy page that compounds into meaningfully faster loads — one of the cheapest performance wins available.
Is WebP supported everywhere?
All modern browsers, WordPress, Shopify, and every major CDN support it. The stragglers are older desktop software and some email clients — keep JPGs for email.
Are my images uploaded to a server?
No. Conversion runs entirely in your browser using its built-in image engine — files never leave your device, which also makes it faster than upload-based converters and safe for private photos.
