Frequently Asked Questions

What is WebP?

WebP is an image format developed by Google that achieves smaller file sizes than JPG or PNG while maintaining similar image quality. It's widely used to improve website loading speeds.

How much smaller will my files be after converting to WebP?

Typically around 25–35% smaller than JPG and over 26% smaller than PNG. The exact savings depend on the image content, but it's highly effective for web optimization.

Should I choose lossy or lossless compression?

For photos with rich colors, lossy compression will reduce the file size more. For logos, icons, and images with text where sharpness matters, choose lossless compression.

Do all browsers support WebP?

Yes, all modern browsers — including Chrome, Firefox, Safari (since 2020), and Edge — support WebP. Older versions of Internet Explorer do not.

Does transparency in a PNG image stay intact when converting to WebP?

Yes, WebP supports transparency (alpha channel). Converting a PNG with a transparent background to WebP will preserve the transparency.
