This free JPEG to WebP converter creates smaller WebP versions of .jpeg and .jpg images directly in your browser. It is built for website owners, SEOs, developers, bloggers, and anyone preparing images for fast pages.
Drop your JPEG files above, choose a quality level, and download WebP output in seconds. Your images never leave your device.
JPEG to WebP vs JPG to WebP
JPEG and JPG refer to the same image format. Some files use the .jpeg extension and others use .jpg. This converter supports both, so you can use it for either extension. If you prefer the shorter keyword page, see JPG to WebP.
Why Convert JPEG to WebP?
WebP usually produces smaller files than JPEG at similar visual quality. That makes it useful for:
- Blog images and article thumbnails
- Product photography
- Hero banners and landing pages
- Portfolio galleries
- WordPress, Shopify, Webflow, and custom websites
Smaller images improve perceived load speed and can help Core Web Vitals, especially Largest Contentful Paint. Learn more in our WebP SEO guide.
How to Convert JPEG to WebP Online
- Upload JPEG images — drag files into the converter or click to browse.
- Pick a quality setting — Balanced (80%) is a strong default.
- Review savings — after conversion, compare original size, WebP size, dimensions, and savings.
- Download WebP files — save individually or download all converted files.
Everything runs locally with browser APIs. There is no waiting for a server queue and no upload privacy risk.
Best JPEG to WebP Quality Settings
| Image type | Starting quality |
|---|---|
| Blog images | 78–82% |
| Product photos | 82–86% |
| Hero images | 84–88% |
| Small thumbnails | 72–78% |
Use the lowest quality that still looks good at the display size you need. Large original photos often remain visually sharp after meaningful compression.
Tips Before Uploading to Your Website
- Resize oversized camera images before publishing if your layout only displays them at smaller dimensions.
- Use descriptive filenames such as
product-name.webp. - Add useful
alttext in your CMS. - Keep original JPEG files as backups.
- Test page speed after switching large JPEG assets to WebP.

Frequently Asked Questions
Common questions about WebP conversion and privacy.
Is WebP better than JPG?
WebP generally produces smaller files than JPEG at the same visual quality. It also supports transparency, which JPEG does not. For photographs on the web, WebP is usually the better choice.
What quality setting should I use?
For most web use, a quality setting of 75–85 provides an excellent balance between file size and visual quality. Lower values reduce file size further; higher values preserve more detail.
Are my images uploaded to a server?
No. All conversions happen entirely in your browser using the Canvas API. Your images never leave your device, making this tool fully private and secure.
How does WebP improve SEO?
Smaller images load faster, which improves Core Web Vitals metrics like Largest Contentful Paint (LCP). Google uses page speed as a ranking factor, so optimized images can help your SEO.
Do all browsers support WebP?
WebP is supported by all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. If you need compatibility with very old browsers, keep a JPEG fallback.
Can I convert multiple images at once?
Yes. Drag and drop multiple files or select them using the file picker. Each file is converted individually and you can download them one by one or use Download All.
