WebP Converter — Make Your Images Smaller and Faster
Convert your JPG and PNG images to WebP, Google’s modern image format that typically reduces file size by 25–35% with no visible quality loss. Smaller images mean faster page loads, better Core Web Vitals, and improved SEO. Everything happens in your browser — your images are never uploaded.
Why WebP?
- Smaller files: WebP compresses better than JPG and PNG at the same quality
- Faster pages: lighter images load quicker, improving user experience and search ranking
- Wide support: all modern browsers (Chrome, Firefox, Safari, Edge) support WebP
- Transparency + animation: WebP supports both, unlike JPG
How to use it
- Drop a JPG or PNG image, or click to browse
- Adjust the quality slider — 75–85% is a great balance of size and quality
- See the before/after size comparison update live
- Download your optimized WebP file
Quality tips
- Photos: 75–85% quality usually looks identical to the original at a fraction of the size
- Graphics with sharp edges: use higher quality (90%+) to keep lines crisp
- Watch the preview: lower the quality until you notice a difference, then step back up
Browser support note
This tool uses your browser’s built-in canvas WebP encoder. It works in all modern browsers. The visual quality of the WebP output may vary slightly between browsers, but the file will be a valid WebP everywhere.
Privacy
Your image never leaves your device. All conversion happens locally using the HTML canvas — nothing is uploaded to any server.
