Re-encoding JPGs as WebP is the quickest bandwidth win for a website: the same visual quality at roughly a third the size, supported by every modern browser and invisible to visitors. Because WebP re-compresses the photo, start from the best-quality JPG you have rather than one that has already been saved many times. The whole batch is processed locally in your browser, with nothing uploaded.
How to use the jpg to webp converter

Frequently asked questions
Should I use WebP for email attachments or documents?
Not yet — many email clients and older Office versions still handle WebP poorly. For attachments and documents, stick with JPG or PNG; reserve WebP for images you publish on the web.
Will converting an already-compressed JPG to WebP hurt quality?
Re-encoding always discards a little detail, but at high-quality WebP settings it is usually imperceptible. Convert from your best original rather than a heavily re-saved copy to keep the result clean.
Are my JPG files uploaded anywhere?
No. The conversion uses your browser's built-in image engine (the Canvas API), so your JPG never leaves your computer. You can verify it by loading this page, going offline, and converting anyway — it still works.
Can I convert several JPG files at once?
Yes — select or drop multiple JPG images and each one is converted to WebP and listed separately for download, all locally on your device.
