Free JPG to WebP Converter
SmarterSources's JPG to WebP converter transforms your JPEG images into Google's modern WebP format directly in your browser. WebP delivers 25-35% smaller file sizes than JPG at equivalent visual quality, making it the ideal format for websites, apps, and anywhere performance matters.
Why Convert JPG to WebP?
WebP was developed by Google specifically for the web. It uses advanced compression techniques that produce significantly smaller files than JPEG while maintaining the same perceived quality. Switching from JPG to WebP means faster page loads, lower bandwidth costs, and better Core Web Vitals scores — all of which directly impact SEO rankings and user experience.
How It Works
Drop your JPG files into the converter, adjust the quality slider to balance file size and visual fidelity, and click Convert All. The tool reads each image using the browser's built-in decoding, draws it to an off-screen canvas, and re-encodes it as WebP at your chosen quality level. Everything happens locally — your images are never uploaded to any server.
Batch Conversion
Need to convert an entire folder of JPG images? Drag and drop multiple files at once. Each file is converted individually with its own size comparison, and you can download results one at a time or all together. This makes it easy to migrate an entire image library to WebP in minutes.
Privacy Guarantee
SmarterSources converts your JPG images entirely within your browser. No files are uploaded to any server. Your images never leave your device, making this the most private JPG to WebP converter available online.
Frequently Asked Questions
What is WebP and why should I use it?
WebP is a modern image format developed by Google that provides superior lossy and lossless compression for web images. It typically produces files 25-35% smaller than JPEG at equivalent visual quality. All major browsers — Chrome, Firefox, Safari, and Edge — fully support WebP, making it safe to use across the web.
Do all browsers support WebP?
Yes. As of 2024, all modern browsers including Chrome, Firefox, Safari (14.1+), Edge, and Opera fully support WebP. Global browser support exceeds 97%. The only browsers that don't support it are Internet Explorer and very old versions of Safari, which represent a negligible share of web traffic.
Will converting JPG to WebP reduce image quality?
At the default quality setting of 0.80, the visual difference between the original JPG and the resulting WebP is virtually imperceptible to the human eye. WebP's compression algorithm is simply more efficient than JPEG's, so it can achieve smaller file sizes without additional quality loss. You can adjust the quality slider to find the perfect balance for your needs.
How much smaller are WebP files compared to JPG?
WebP files are typically 25-35% smaller than equivalent-quality JPEG files. The exact savings depend on the image content and the quality setting you choose. Photographs with lots of detail tend to compress especially well. You can see the exact savings for each file after conversion.
Can I convert multiple JPG files at once?
Absolutely. Drag and drop as many JPG files as you need, or use the file picker to select multiple files. Each image is converted with the same quality setting, and you can download them individually or all at once. There's no limit on the number of files you can convert in a single batch.
