JPG to WebP converter

WebP is the modern image format developed by Google. For photographic content, it produces files that are 25–35% smaller than JPG at the same visual quality — sometimes more. For graphics with flat colors, the savings can exceed 50%.

This converter turns your JPG files into WebP in your browser, with full quality control. All major browsers now support WebP natively, including Safari (since 2020), so it's safe to use across the web.

How JPG to WebP conversion works

Why WebP beats JPG

WebP was designed specifically to address JPG's age (it was standardized in 1992). It uses smarter compression techniques that produce smaller files for the same visual quality:

• Smaller files, same quality. For typical web photos, WebP produces files 25–35% smaller than JPG at the equivalent quality level. The savings compound across an entire website.
• Faster page loads. Smaller images mean faster page loads, which matters for SEO (Google factors page speed into rankings) and user experience.
• Better browser support than you think. WebP works in Chrome (since 2010), Edge, Firefox, Opera, Safari (since iOS 14), and every modern browser. Coverage is effectively 100% of modern web traffic.
• Lossless mode also available. Unlike JPG, WebP supports lossless compression for screenshots, diagrams, and graphics where every pixel matters.
• Transparency support. WebP has full alpha-channel support, unlike JPG — useful when you don't need pure PNG but want a transparent background.

When to use this tool

JPG to WebP conversion is especially valuable in these scenarios:

• Optimizing a website. Convert all your product images, hero photos, and content images to WebP and watch your page weight drop dramatically.
• Reducing storage costs. For services that store millions of user-uploaded JPGs, WebP can cut storage and bandwidth costs by a third or more.
• Email attachments. Most modern email clients (Gmail, Outlook, Apple Mail) display WebP inline. Smaller attachments = faster send.
• Mobile apps. Smaller image downloads on mobile means less data, faster screens, happier users.

When you don't want WebP: if you need backwards compatibility with old systems (Internet Explorer, ancient Android), or if the receiving system specifically requires JPG.

Choosing quality settings

WebP quality works similarly to JPG quality — a number from 0 to 100 controlling compression aggressiveness:

• 90–100%: near-lossless. Best for archives. Files still smaller than JPG at the same setting.
• 80–90%: the standard for high-quality web use. Visually identical to the source.
• 70–80%: aggressive optimization, suitable for most web images. Faint artifacts only on close inspection.
• 50–70%: for thumbnails and previews where speed matters more than quality.

Default to 85% if you're not sure. It's the right choice for ~95% of web images.

Convert without uploading

Other JPG-to-WebP services upload your files to their servers. We don't. The entire conversion happens in your browser using the native Canvas API.

This is especially valuable when you're converting product photos, design comps, or anything else you wouldn't want sitting on someone else's server. Our approach also means there's no rate limit, no file size cap based on our bandwidth, and no waiting for upload progress.
