Frequently asked questions

Are my images uploaded anywhere?

No. The conversion runs locally in your browser using the canvas API — your images never leave your device.

Why convert JPG to WebP?

WebP typically produces 25–35% smaller files than JPG at similar visual quality, which means faster page loads if you're using the image on a website.

Will every site or app accept a WebP file?

Almost all modern browsers and platforms support WebP. A few older tools and some print or upload workflows still expect JPG or PNG — check before relying on it everywhere.
