WebP quality
84%
Higher quality keeps more detail. Lower quality usually creates a smaller WebP.
WebP output
Transparent PNG pixels can remain transparent. JPG and JPEG sources convert as flattened photo images.
Upload a PNG, JPG, or JPEG image, choose the WebP quality, then generate the WebP file.
The output keeps the original pixel dimensions and runs locally in your browser, so it works well for product images, blog graphics, and website assets.
WebP supports transparency, so transparent PNG pixels can stay transparent in the converted file.
JPG and JPEG files are already flattened images, so the WebP output will keep the visible photo pixels without adding transparency.
A quality value around 80 to 88 is a good starting point for most web images.
Use a higher value for UI screenshots, sharp text, or logos. Use a lower value when smaller file size matters more than perfect detail.
The browser decodes the source image, draws it onto a canvas, and saves the result as a WebP file.
No. The conversion runs locally in your browser with Canvas APIs. Your PNG, JPG, or JPEG image is not sent to a server by this tool.
Yes. If the source is a transparent PNG and your browser encodes WebP correctly, transparent pixels can remain transparent in the WebP output.
WebP usually creates smaller web-ready images while supporting both photo compression and transparency, which makes it useful for modern websites.
