JPG to WebP Converter
JPG to WebP Converter is a free online tool that turns JPG images into WebP format directly in your browser. JPG (JPEG) is a lossy format optimised for photographs, producing small files at the cost of some detail. WebP is a modern Google format that delivers smaller files than JPG or PNG with support for transparency. Drop your JPG file, adjust the quality, and download the WebP instantly — your file never leaves your device, with no upload, server or sign-up required.
Your files never leave your device. Conversion runs locally in your browser using the HTML canvas API. No upload, no server, no storage.

Frequently Asked Questions
How do I convert JPG to WebP?
Drop your JPG file onto the converter (or click to browse), set the output quality, then click Convert and download your WebP image. Everything happens in your browser — no upload required.
Is my JPG file uploaded to a server?
No. The conversion runs entirely in your browser using the HTML canvas API. Your JPG file never leaves your device and is never sent to any server. You can verify this by opening Chrome DevTools → Network while converting.
Does the WebP keep transparency?
JPG has no transparency to preserve, but the resulting WebP is lossless and can have transparency added later in an image editor.
Can I control the WebP quality and file size?
Yes. Use the quality slider (1–100%) before converting. Lower quality produces a smaller file; 80–90% is a good balance of size and visual quality for most images.
Can I convert several JPG files at once?
Yes. You can add up to 5 JPG files and convert them in one batch, then download each WebP individually or all together.
Is the JPG to WebP converter free?
