Convert images to WebP
The WebP Converter turns JPG and PNG images into the modern WebP format, with an adjustable quality slider and a live view of the size savings. WebP usually produces much smaller files than JPG or PNG at the same visual quality, which speeds up your website. Everything runs in your browser, so your images are never uploaded.
Why WebP?
WebP is a modern image format from Google that offers superior compression — typically 25–35% smaller than JPG and far smaller than PNG for the same quality. Smaller images mean faster page loads, better Core Web Vitals, and lower bandwidth. WebP is now supported in every major browser, making it the go-to format for web images.
How to use it
- Upload a JPG or PNG image.
- Adjust the quality and watch the size savings.
- Download the optimized WebP file.
WebP vs JPG vs PNG
| Format | Strength |
|---|---|
| WebP | Best compression; supports transparency & quality control |
| JPG | Universal, good for photos, larger files |
| PNG | Lossless & transparent, but large for photos |
Choosing quality
For most web images, 75–85% WebP quality looks excellent while dramatically cutting file size. Lower it further for thumbnails where size matters more than detail. Compare the preview to judge the sweet spot — WebP often looks better than a JPG of the same file size.
Private by design
Conversion happens locally using your browser's canvas, so your images never leave your device. There's no upload wait and no server ever sees your files — ideal for personal photos and confidential graphics.
Private and free
The converter is completely free with no sign-up and no watermarks. Convert as many images as you like.
