What is WebP and why is it better than JPG or PNG?

WebP is a modern image format tailored for the web. It offers superior lossless and lossy compression, meaning your images will be 25-34% smaller than comparable JPGs or PNGs without visible quality loss. This makes websites load significantly faster.

Is this WebP Converter free to use?

Yes, this tool is 100% free and open for everyone. There are no daily limits, paywalls, or hidden costs. You can convert as many images as you need.

Is there a file size or count limit?

No, explicitly not. Because the conversion runs entirely in your browser (client-side), we don't impose arbitrary limits on file size or the number of images you can upload at once.

Does this tool support transparency (alpha channel)?

Yes! If you convert a PNG with a transparent background to WebP, the transparency will be preserved in the output file.

Are my images uploaded to the server?

No. Your privacy is our top priority. All processing happens locally in your web browser. Your photos never leave your device.

What is the best quality setting for WebP?

We recommend a quality setting between 75% and 85%. This range typically offers the best balance, reducing file size significantly while keeping the image looking sharp to the human eye.

How it Works

Our tool uses the browser's native Canvas API and built-in image encoders to convert your files. When you upload an image, we draw it onto an offscreen canvas and then export it using modern compression algorithms.

WebP Technology

Developed by Google, WebP uses predictive coding to encode images, creating smaller files that look identical to JPGs and PNGs at much lower bitrates.
