JPG to WebP

Shrink JPG photos into modern WebP files for faster websites — right in your browser, nothing uploaded.

Why WebP for the web

Images are usually the heaviest part of a web page, and page speed directly affects bounce rates and search rankings. WebP typically delivers the same visual quality as JPG in 25–35% fewer bytes, which means faster loads with no visible change for your visitors. Converting your existing JPG library is one of the cheapest performance wins available.

How it works

This page mounts the WebP converter with WebP output pre-selected. Your JPGs are decoded and re-encoded by the browser’s canvas API — locally, with nothing uploaded. Pick a quality level, run the batch, and compare the before/after sizes shown on each result. Up to 20 files per batch, downloadable individually or as a ZIP.

Choosing a quality level

Remember the source was already a lossy JPG, so you are re-encoding compressed data. High quality keeps the damage invisible; aggressive settings compound artifacts.

Compatibility notes

Measure the win

After converting, compare the total bytes before and after — most photo libraries shrink by a quarter to a third. Multiply that by your monthly image bandwidth and you have the business case. Serve WebP with JPG fallback via the <picture> element and every visitor gets the best format their browser supports, with zero downside.

Private by design

Conversion happens entirely on your device. No uploads, no queues, no watermarks.

Frequently asked questions

How much smaller is WebP than JPG?

Typically 25–35% smaller at equivalent visual quality for photographs. The exact saving depends on image content — smooth gradients compress best.

Will WebP images work on all browsers?

All modern browsers (Chrome, Edge, Firefox, Safari 14+) display WebP. If you must support very old clients, keep a JPG fallback.

Does converting JPG to WebP lose quality?

JPG is already lossy, and WebP re-encodes it, so technically yes. At the High quality setting the difference is invisible in practice.

Can I batch convert?

Yes: up to 20 files per batch, 20 MB each, 80 MB total, with a single ZIP download.

What if my browser can’t encode WebP?

You need a recent version of Chrome, Edge, Firefox or Safari. Older browsers may lack a WebP encoder entirely.

Are my images uploaded?

No. The canvas API encodes everything locally in your browser tab.
