How It Works
Drop your JPG files
Drag and drop or select JPG/JPEG images from your device. Batch conversion is supported — add as many files as you need.
Canvas renders the image
Each JPG is decoded by your browser's native JPEG decoder and rendered onto an HTML Canvas element at full resolution. No data leaves your device.
VP8 WebP encoding at 80%
The Canvas exports the image as WebP using the browser's built-in VP8 encoder at 80% quality. This achieves 25-35% smaller files compared to the JPG source with no visible quality difference.
Download smaller WebP files
Your optimized WebP files are ready. Use them on your website for faster loads, better Core Web Vitals, and lower bandwidth costs.
// under the hood
JPG uses DCT (Discrete Cosine Transform) lossy compression, while WebP uses Google's VP8 codec which achieves better compression at equivalent quality. Our converter renders the JPG onto an HTML Canvas element and exports via toBlob with 'image/webp' MIME type at 80% quality. The browser's native VP8 encoder handles the compression, producing files typically 25-35% smaller than the JPG source.

Frequently Asked Questions
- What is WebP and why is it better than JPG?
- WebP is a modern image format developed by Google that uses VP8 compression. It delivers 25-35% smaller file sizes than JPG at equivalent visual quality. WebP is supported by all major browsers and is the recommended format for web images by Google PageSpeed Insights.
- Why convert JPG to WebP?
- WebP files load faster on websites, reduce bandwidth costs, and improve Core Web Vitals scores — a direct SEO ranking factor. If you run a website or web app, serving WebP instead of JPG is one of the easiest performance wins available.
- Does converting to WebP reduce image quality?
- Our converter uses 80% WebP quality, which produces files that are visually indistinguishable from the JPG source for most images. The VP8 codec is more efficient than JPG's DCT compression, so you get smaller files without visible quality loss.
- Can I batch convert multiple JPGs?
- Yes. Drag and drop or select as many JPG files as you need. All files are converted simultaneously in your browser and can be downloaded individually or all at once.
- Are my images uploaded to a server?
- No. Every conversion runs entirely in your browser using the Canvas API. Your images never leave your device — we have zero access to your files. You can even disconnect from the internet and it will still work.
