JPG to WebP

What is a JPG to WebP converter?

It re-encodes a JPEG photo into the WebP format. Both are lossy formats for photos, so the picture looks the same, but WebP files are normally 25–35% smaller — that is why almost every modern website serves images as WebP.

Why convert JPG to WebP?

• Faster pages. Smaller images load quicker and use less bandwidth; Google uses page speed as a ranking signal.
• Better Core Web Vitals. Lighter images improve Largest Contentful Paint, the metric most affected by images.
• Same look, less weight. At equal visual quality WebP wins on size for photos.

How to use

• Drop one or more JPG/JPEG files.
• Set the quality (0.80–0.90 is a good balance) and convert.
• Download the WebP files and see how much weight each one lost.

JPG vs WebP at a glance

• JPG — maximum compatibility, supported literally everywhere.
• WebP — smaller files, plus optional transparency, supported by all current browsers.

Keep JPG for print and legacy apps; use WebP for anything you put on a website.

Good to know

• Some very old software cannot open WebP — if you need a universal file, stay with JPG.
• Everything runs locally in your browser: no upload, no account, no watermark, up to 30 MB per file.

FAQ

Is WebP smaller than JPG?

Which quality should I pick?

0.90 keeps photos looking identical to the eye. Use 0.80–0.85 for big galleries or web pages where a few KB matter; use 1.0 only if you plan to re-edit the file.

Can I convert many files at once?

Yes. Select or drop multiple JPG files; each is converted in order and listed with its own download link.
