Convert png to webp when you want a PNG image to load faster on a website without losing the transparent background. This tool turns PNG files into smaller WebP files, keeps transparency, and handles several images in one go. It is free, needs no account, and every file you upload is deleted within an hour.
How to convert PNG to WebP
- Drop your PNG file, or several PNG files, into the box above.
- Wait a few seconds while the box above turns each one into WebP.
- Download the WebP files, either one by one or all together.
When you need WebP instead of PNG
- Your website is slow to load because product photos or logos are saved as PNG.
- You need a transparent logo or icon that weighs less than the PNG version.
- A CMS, ad platform, or app store asks for WebP images specifically.
- You are cleaning up a folder of screenshots or graphics before uploading them.
What you get
Each PNG comes out as a WebP file with the same transparent areas, usually at a noticeably smaller size. Because the tool works on several images at once, you can convert a whole folder of icons or screenshots without doing them one at a time. There is no watermark added, and nothing is saved to an account, since there is no account to sign into.
Limits to know
The files you upload sit on the server only long enough to convert them, then they are deleted within an hour, so do not treat this as storage. WebP is supported by all current browsers, but if you need a file for very old software, keep a PNG copy as well.
