JPG to WebP Converter

Convert JPEG photos to smaller WebP images — private, in your browser

Turn JPEGs into lighter WebP images

WebP is the modern image format built for the web: it keeps photos looking the same as JPEG while making the files noticeably smaller — usually 25–35% lighter at matching quality. Smaller images mean faster-loading pages, less bandwidth and better Core Web Vitals scores, which is why WebP is now the default export on most performance-focused sites. This converter turns your JPG or JPEG files into WebP without uploading a thing.

Drop one photo or a whole batch, nudge the quality slider until the preview looks right, and download a single WebP or a ZIP of all of them. The before/after file size is shown for every image so you can see exactly what you are saving.

How to convert JPG to WebP

  1. Drop your JPG/JPEG files into the box above (or click to choose them).
  2. Set the quality slider — 80–90 keeps photos visually identical while still shrinking the file.
  3. Check the live preview and the before/after size readout.
  4. Click Download WebP (or Download all (ZIP) for a batch).

Why choose WebP over JPG?

Smaller files, same quality

WebP's compression is more efficient than JPEG's, so at a given visual quality the file is smaller. For image-heavy pages that adds up to real load-time savings.

One format for photos and graphics

Unlike JPEG, WebP also supports transparency and animation, so a site can standardise on a single modern format instead of juggling JPG and PNG.

Private by design

Every conversion runs locally through your browser's canvas engine. Your JPGs are never sent to a server, so this is safe for personal photos, client work and anything unpublished.

Frequently Asked Questions

Are my images uploaded to a server?

No. The conversion happens entirely in your browser — your JPG files never leave your device.

How much smaller is WebP than JPG?

Typically 25–35% smaller at the same visual quality. The tool shows the before/after file size for each image so you can see the exact saving.

Will I lose quality converting JPG to WebP?

You control it with the quality slider (10–100). Around 80–90 keeps photos visually identical; lower values trade quality for a smaller file.

Can I convert several JPGs at once?

Yes — add multiple files and download them all as a single ZIP of WebP images.

Do all browsers support WebP?

Chrome, Edge, Firefox, Opera and Safari 14+ all display WebP. It is the standard format for fast-loading sites today.
