    What is PNG?

    PNG is a lossless format that keeps every pixel and supports transparent backgrounds. It is ideal for logos, screenshots and graphics, but photos saved as PNG are large.

    Why convert to WebP?

    WebP is a modern web format from Google. It is usually 25–35% smaller than JPG at the same quality and supports transparency, but some older apps and editors can’t open it.

    Private and free

    Your images are converted by your own browser and never uploaded to a server. There’s no sign-up, no watermark and no limit on how many times you use it.

    Frequently asked questions

    How do I convert PNG to WebP?

    Drop your PNG files onto the box above or click to choose them. They are converted to WebP straight away; press Download for each one, or Download all to get a ZIP. You can change the output format or quality in the settings at any time.

    What happens to transparent areas?

    JPG doesn’t support transparency, so transparent areas are filled with a background color, white by default. You can pick another color in the settings. WebP and PNG keep transparency.

    Can everyone open WebP files?

    All modern browsers (Chrome, Edge, Firefox and Safari) display WebP, and so do recent versions of Windows, macOS, Android and iOS. Some older software and print services don’t, so keep a JPG copy for those.

    Are my images uploaded to a server?

    No. The conversion happens inside your browser on your own device, so your photos are never uploaded, stored or seen by anyone. It also works offline once the page has loaded.

    Is there a limit on file size or number of images?

    You can convert up to 50 images at a time. There is no file size limit beyond what your device’s memory can handle; very large photos (over 50 megapixels) may be slow on older phones.
