What Is JPG to WebP Conversion?

WebP is Google's modern image format built for the web. At equivalent visual quality it typically produces files 25–34% smaller than JPEG, which means faster pages and lower bandwidth. Converting JPG to WebP is one of the easiest wins for website performance and Core Web Vitals.

100% private: every image is converted right inside your browser using the Canvas API. Your files are never uploaded to a server.

Common Use Cases

Faster Websites

Lighter images speed up page loads and improve SEO scores.

Save Bandwidth

Smaller files cut hosting and CDN transfer costs.

Bulk Optimize

Convert a whole folder of JPGs to WebP in one batch.

How to Convert JPG to WebP

1

Add Your JPG Files

Drag and drop your JPG images onto the upload zone, or click to browse. You can add up to 20 files at once.

2

Set the Quality

Move the quality slider (10–100) to balance WebP file size against visual sharpness. The default of 85 suits most images.

3

Automatic Conversion

Conversion starts the moment your files are added — no extra button to press. Each JPG image is rendered to WebP in your browser.

4

Download Your WebP Files

Save each WebP file individually, or click Download All (ZIP) to grab the whole batch in one archive.

Features & Format Details

WebP keeps photos looking sharp while cutting weight, and it is supported by all modern browsers. The quality slider lets you fine-tune the balance between size and clarity for each batch of images.

Frequently Asked Questions

Do all browsers support WebP?

Yes. All current versions of Chrome, Firefox, Safari, and Edge display WebP. It is now a safe default for the web; for very old browsers you can keep a JPG fallback.

Are my images uploaded to a server?

No. Conversion runs entirely in your browser with the Canvas API, so your JPG files are never sent anywhere. This makes the tool safe even for private or confidential images.

How many files can I convert at once?

You can add up to 20 images at a time. After conversion you can download each WebP file separately or all of them together as a ZIP archive.

Is this converter really free?

Yes. It is completely free with no account required, no watermarks added to your images, and no limit on how many conversions you can do.
