Convert JPG to WebP

Add your JPG files below — WebP is already selected as the output format. WebP files are typically 25–35% smaller than JPEGs of the same visual quality, which makes pages load faster and helps Core Web Vitals.

All modern browsers display WebP. Everything runs on your device — nothing is uploaded — and you can resize to your site's display size in the same pass for even smaller files.

Batch-compress, resize, crop, rotate, watermark, and convert formats — right in this tab.

JPEG · PNG · WebP · HEIC · AVIF (where supported) — your photos never leave this browser tab

Nothing here yet — add photos above to get started.

Only helps if your background is already one plain color (e.g. a wall) — this is color-distance math, not real subject cutout, so it won't do anything useful against busy or textured backgrounds.

You'll crop it to the exact aspect ratio next.

Frequently asked questions

Why convert JPG to WebP?

Smaller files at the same visual quality mean faster page loads and lower bandwidth — the main reason WebP is recommended by page-speed tools.

Do all browsers support WebP?

Every current version of Chrome, Edge, Firefox and Safari does. Some older software, email clients and government forms still expect JPG — keep a JPG copy for those.

What quality setting should I use?

Between 70 and 85 looks indistinguishable from the original for most photos. Use Max file size mode if you have a byte budget per image.

Can I convert back to JPG later?

Yes — use the WebP to JPG converter.
